Some occurences are missed by the automatic conversion, those will be handled in a seperate patch. Signed-off-by: Patrick McHardy Signed-off-by: David S.

The minimum frame size that can be received by the hardware is 57 Bytes. A 64 Byte Ethernet frame with the vlan tag and fcs stripped will result in a 56 Byte frame which will lock up the receive engine. The work around is to disable fcs stripping in the hardware which is done with a firmware upgrade. The fixes are - 1. Ensure that the correct firmware version is used. 2.

This will significantly reduce the likelyhood of order:3 allocation failures. This new code adds support for using pages as receive buffers, and the driver will chain multiple pages together to build a jumbo frame for OS consumption. The hardware takes a power of two buffer size and will dump as much data as it can receive into 1 or more buffers. The benefits of applying this are 1) stop akpm's dissing :-) of this lame e1000 behavior [1] 2) more efficient memory allocation (half) when using jumbo frames, which will also allow for much better socket utilization with jumbos since the socket is charged for the full allocation of each receive buffer, regardless of how much is used. 3) this was a feature request by a customer 4) copybreak for small packets < 256 bytes still applies [1] http://lkml.org/lkml/2008/7/10/68 http://article.gmane.org/gmane.linux.network/130986 Signed-off-by: Jesse Brandeburg CC: Andrew Morton Signed-off-by: Jeff Kirsher Signed-off-by: David S.

In fact, before this change, the FCRTH (xoff threshold) is 36864 when the fifo size is only 40000, with 9000 byte MTU. fix it so that we at least have room for one frame after we send the xoff.

Now all commands need to contain all the needed headers, either just cmd headers or both cmd and acx headers. This accomplish to remove the extra copy done for each command. The interfaces are now properly documented as well. Also try to make all commands safe for DMA transfers. I might have missed some, but most of them should be fixed now. And this is not all! As a free bonus you will also get some cosmetic cleanups and code reorganisation. Order today! Signed-off-by: Kalle Valo Signed-off-by: John W.

This is wasteful, as drivers could be building it in there to start with. This patch changes the API so that drivers are expected to pass the RX status in skb->cb, now accessible as IEEE80211_SKB_RXCB(skb). It also updates all drivers to pass the rx status in there, but only by making them memcpy() it into place before the call to the receive function (ieee80211_rx(_irqsafe)).

Store the orinoco_private structure in the new wiphy, and use the net_device private area to store the wireless_dev. This results in a change to the way we navigate from a net_device to the driver private orinoco_private, which we encapsulate in the inline function ndev_priv. Most of the remaining calls to netdev_priv are thus replaced by ndev_priv. We can immediately rely on cfg80211 to handle SIOCGIWNAME, so orinoco_ioctl_getname is removed.

There's no multiplexing like like iwpriv had, and the command is not available by default, it needs to be explicitly enabled in Kconfig and shouldn't be enabled in most kernels. The command requires a wiphy index or interface index to identify the device to operate on, and the new TESTDATA attribute. There also is API for sending replies to the command, and testmode multicast messages (on a testmode multicast group). I've also updated mac80211 to be able to pass through the command to the driver, since it itself doesn't implement the testmode command. Additionally, to give people an idea of how to use the command, I've added a little code to hwsim that makes use of the new command to set the powersave mode, this is currently done via debugfs and should remain there, and the testmode command only serves as an example of how to use this best -- with nested netlink attributes in the TESTDATA attribute. A hwsim testmode tool can be found at http://git.sipsolutions.net/hwsim.git/. This tool is BSD licensed so people can easily use it as a basis for their own internal fabrication and validation tools.

This copy is checked when deciding whether or not to return to sleep in IEEE PS mode but the actual copying back to priv was omitted, which breaks IEEE PS mode with WPA/WPA2 when one issues commands that require temporarily keeping the device awake. This patch introduces the omitted copy-back of the keys so that IEEE PS functions correctly in WPA/WPA2 mode. Thanks to Dan Williams for clearing up the issue. V2: fix typo.

If IEEE PS is enabled, this results in the card being left in IEEE PS mode and subsequent failures to reload the module. The problem is that the surpriseremoved flag is set before calling lbs_remove_card, but that function needs to issue a command to exit IEEE PS mode (the flag blocks the command path). In addition, lbs_stop_card should be called first because it clears out any pending commands. Tested on a GSPI device with V9 firmware by confirming that we can reload the module with or without IEEE PS enabled. Also fix a warning from the wrong uint format in a printk.

With IEEE PS enabled, lbs_remove_card must issue a command to exit IEEE PS mode, however with that flag set the command path is blocked and the card is never taken out of IEEE PS mode. This step is required to ensure that the driver can be reloaded. This patch moves the setting of surpriseremoved after lbs_remove_card is called. Tested with V9 firmware by ensuring that IEEE PS is disabled when the driver is removed. Reloading the driver is not fully tested due to a separate issue with module reload in the SDIO driver, however this patch at least leaves the card in a better state when we bring the driver down.

This change adds a state variable for beaconing in ath5k_beacon_config and handles both enabling and disabling, thus eliminating the need for ath5k_beacon_disable. We also now configure the beacon when any of the beacon parameters change, so ath5k_beacon_reconfig is no longer needed (its mmiowb gets moved to ath5k_beacon_config). Finally, by locking around the whole config function, we don't need to worry about clearing the interrupt mask register before installing the new mask. The upshot is this correctly disables beaconing when the interfaces are taken down, it fixes a potential restarting of beaconing when ath5k_reset() is called, and ensures that updates to the beacon interval take effect immediately.

This doesn't make much sense to encode the pointer in documentation as it prevents proper C type checking from occurring and can easily allow people to use the wrong pointer type.

Set minimum to be 10 to provide for 4 standard TX queues + 1 command queue + 2 (unused) HCCA queues + 4 HT queues (one per AC). We allow the user to change the number of queues used via a module parameter and use this minimum value to check if it is valid. Without this patch a user can select a value for the number of queues that will result in a failing setup.

Not all AP are compatible with the driver(and firmware) yet, so YMMV. A more refined code will definitely need the final HT specification to be available for the public, lots of firmware modification and possibly a redesigned driver just for good measure. Sadly, these conditions won't come true anytime soon... Signed-off-by: Christian Lamparter Signed-off-by: John W.

Running iperf along with p2p traffic on both TX and RX side then stop one side, then stop the other side, then start it up again, eventually the STA gets into a mode that it can not pass data at all. A hardware workaround for invalid RSSI can make FIFO write pointer to jump over read pointer, causing RX data corruption and repeated DMA. Both TX and RX works fine when the workaround is disabled. To replace the original hardware work around, software looks for frames with post delimiter CRC error and mark the RSSI invalid so that the upperlayer will not use the RSSI associated with this frame. So disable the hardware workaround by updating the appropriate registers. Signed-off-by: Senthil Balasubramanian Signed-off-by: John W.

This behavior of the hardware not generating the TX interrupts can be noticed through ath9k debugfs interrupt statistics when heavy traffic is being sent from STA to AP. One can easily see this behavior when the STA is transmitting at a higher rates. The interrupt statistics in the debugfs interface clearly shows that only RX interrupts alone being generated and TX being stuck. TX should be monitored through a timer and reset the chip only when frames are queued to the hardware but TX interrupts are not generated for the same even after one second. Also, we shouldn't remove holding descriptor from AC queue if it happens to be the only descriptor and schedule TX aggregation regarless of queue depth as it improves scheduling of AMPDUs from software to hardware queue.

Replace it with "debug" module parameter to match with original driver and be consistent between them. The "debug50" module parameter can still be used, except that the module parameter is not writable in keeping with its previous state. We currently just mark it as "deprecated" and do not have it in the feature-removal-schedule. Some more cleanup of module parameters needs to be done and can then be entered together. * Only make "debug" module parameters visible if the driver is compiled with CONFIG_IWLWIFI_DEBUG. This will eliminate a lot of confusion where users think they have set debug flags but yet cannot see any debug output. * Make module parameters writable. This eliminates the need for the "debug_level" sysfs file, which can now also be deprecated and added to feature-removal-schedule. This file is in significant use though with many iwlwifi documents and text referring users to it. We can thus not take its removal lightly and keep it around. With iwlcore shared between iwlagn and iwl3945 we really do not need debug module parameters for each but can instead have one debug module parameter for the iwlcore module. The same issue is here as with the sysfs file - a lot of iwlwifi documentation and text (like bug reports) rely on iwlagn and iwl3945 having this module parameter, so changing this to a module parameter of iwlcore will have significant impact and we do not do this for that reason. One consequence of this patch is that if a user is running a system with both 3945 and later hardware then the setting of the one module parameter will affect the value of the other. The likelihood of this seems low - and even if this setup is present it does not seem like an issue for both modules to run with the same debug level.

The main purpose of this is to clean out some redundancy that was introduced due to having multiple ways of setting the receive address registers. Instead of having a specialized function to set one register and one to set all of them it makes more sense to just go through the list calling the function that is needed to set the individual registers.

this patch introduce the Legacy Thermal Management: IWL_TI_0: normal temperature, system power state IWL_TI_1: high temperature detect, low power state IWL_TI_2: higher temperature detected, lower power state IWL_TI_CT_KILL: critical temperature detected, lowest power state Once get into CT_KILL state, uCode go into sleep, driver will stop all the active queues, then move to IWL_TI_CT_KILL state; also set up 5 seconds timer to toggle CSR flag, uCode wake up upon CSR flag change, then measure the temperature. If temperature is above CT_KILL exit threshold, uCode go backto sleep; if temperature is below CT_KILL exit threshold, uCode send Card State Notification response with appropriate CT_KILL status flag, and uCode remain awake, Driver receive Card State Notification Response and update the card temperature to the CT_KILL exit threshold.

this patch introduce the Advance Thermal Throttling: TI-0: system power index, no tx/rx restriction, HT enabled TI-1: power index 5, 1 spatial stream Tx, multiple spatial stream Rx, HT enabled TI-2: power index 5: 1 spatial stream Tx, 1 spatial stream Rx, HT disabled TI-CT-KILL: power index 5, no Tx, no Rx, HT disabled For advance Thermal Throttling, CT_KILL_ENTER threshold and CT_KILL_EXIT threshold are different; uCode will not stay awake until reach CT_KILL_EXIT threshold.

By default, 40MHz is supported if AP can support the function. By echo "1" to "disable_ht40" file, iwlwifi driver will disable the 40MHz support and only allow 20MHz channel.

The result is that if beacon configuration (ops->bss_info_changed) happens before ops->config, we will program the wrong things into the timer registers. Consequently, beacons won't work in AP mode until after a reset (channel change, scan etc.). This is fragile anyway so just program the opmode as soon as mac80211 gives it to us.

This situation will only occur under extreme stress. Although b43 does not crash when this condition occurs, it does generate a WARN_ON and also logs a queue overrun message. This patch recognizes b43 is not at fault and logs a message only when the most verbose debugging mode is enabled. In the unlikely event that the queue is not stopped when the DMA queue becomes full, then a warning is issued. During testing of this patch with one output stream running repeated tcpperf writes and a second running a flood ping, this routine was entered with the DMA ring stopped about once per hour. The condition where the DMA queue is full but the ring has not been stopped has never been seen by me. Signed-off-by: Larry Finger Signed-off-by: John W.

We extend mac80211 to document how the mac80211 workqueue should be used, how it should not be used and finally move raw access to the workqueue to mac80211 only. Drivers and mac80211 use helpers to queue work onto the mac80211 workqueue: * ieee80211_queue_work() * ieee80211_queue_delayed_work() These helpers will now warn if mac80211 already completed its suspend cycle and someone is trying to queue work. mac80211 flushes the mac80211 workqueue prior to suspend a few times, but we haven't taken the care to ensure drivers won't add more work after suspend. To help with this we add a warning when someone tries to add work and mac80211 already completed the suspend cycle. Drivers should ensure they cancel any work or delayed work in the mac80211 stop() callback. Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.

In some cases, the device side seems to set the higher bits, causing us to fail the sanity check unnecessarily. Check only the lower four bits instead.

This situation will only occur under extreme stress. Although b43legacy does not crash when this condition occurs, it does generate a WARN_ON and also logs a queue overrun message. This patch recognizes b43legacy is not at fault and logs a message only when the most verbose debugging mode is enabled. In the unlikely event that the queue is not stopped when the DMA queue becomes full, then a warning is issued. This patch is based on the one used by b43.

This patch allows this existing mechanism to work and will increase the configuration flexibility of DCB mode on Linux. A hierarchy of configuration is: 1. Modifies the ixgbe_select_queue() routine for DCB mode to return the priority value from the VLAN tag. It will normally be zero, unless the egress priority map has modified it. This will get packets into the correct queue and result in the queue_mapping field being set correctly. 2. Any tc filter which modifies queue_mapping will be honored, as the filters are handled after the vlan egress map is handled.

The cause is due to the fact that the ->cb[] area of an skb cannot be used in a network driver's transmit path, as that area belongs to the network protocol. Pktgen hangs, as it sends out the same packet multiple times, and vxge's use of this area of the skb for a temporary list can only add the packet to the temporary list once (while it may be on the queue many times). The fix is to remove this abuse of skb->cb[]. Instead, skb pointers are placed into a temporary stack array, and then free outside of the tx lock. This retains the smp optimization of doing dev_kfree_skb() outside of the tx lock.

It required a lot of change in the FW which implies many changes in the driver to support it. It is now also possible for the driver to use a separate MSI-X vector for Rx and Tx - this also add some to the complicity of this change. All things said - after this patch, practically all performance matrixes show improvement. Though Vladislav Zolotarov is not signed on this patch, he did most of the job and deserves credit for that.

Support for wl1273 should be relatively easy to add. This chipset is designed for embedded devices, with good powersaving capabilities. The wl1271 chipset is the successor of wl1251 and supports the 802.11b/g/n standards, but currently this driver supports only b/g.

Also rename wl1251_spi_mem_{read,write} to indicate its common usage. We still use spi_read internally until SDIO interface is introduced so nothing functional should change here.

In doing so it created a single global debug level for all devices. Some setups do consits of more that one iwlwifi device and in these setups there is a requirement that debug levels should be unique per device. We now re-introduce the per device debugging while maintaining the cleanup effort of the previous patch. The maintain the global debug level and now introduce a per-device debug level that will be used if it (the per-device debug level) is set. The per-device debug level can be controlled via the debug_level sysfs file while the global debug level is controlled by the debug module parameter.

How to display the current logged tx/rx traffic and txfifo and rxfifo read/write point: "cat traffic_log" in /sys/kernel/debug/ieee80211/phy0/iwlagn/debug directory By echo "0" to traffic_log file will empty the traffic log buffer and reset both tx and rx taffic log index to 0.

Unfortunately we hit a problem with it frequently enough to make a 4965 unusable. The problem can be seen in debug log below. What this code attempts is to set runtime ucode up to load, start a timer to wait for the alive response from runtime ucode, and if it times out it tries again. As can be seen below we receive the alive response and wake the waiting task _before_ the tasks starts waiting. The task thus times out as the alive response is not received while it is waiting for it and it restarts the device. This starts the cycle all over again.

Also, mac80211 has a user-visible dynamic sleep feature where we are supposed to stay awake after sending/receiving frames to better receive response frames to our packets, this can be integrated into the sleep command. Currently, and this patch doesn't change that yet, we default to using sleep level 1 if PS is enabled. With a module parameter to iwlcore, automatic adjustment to changing network latency requirements can be enabled -- this isn't yet the default due to requiring more testing. The goal is to enable automatic adjustment and then go into the deepest possible sleep state possible depending on the networking latency requirements. This patch does, however, enable IEEE80211_HW_SUPPORTS_DYNAMIC_PS to avoid the double-timer (one in software and one in the device) when transmitting -- the exact timeout may be ignored but that is not of big concern. Note also that we keep the hard-coded power indices around for thermal throttling -- the specification of that calls for using the specified power levels. Those can also be selected in debugfs to allow easier testing of such parameters. Signed-off-by: Johannes Berg Signed-off-by: Reinette Chatre Signed-off-by: John W.

The oops is caused by one of the following race conditions: * In case of two near calls to set_tim: rt2x00lib_beacondone_iter is cleaning the beacon skb, whereas rt73usb_write_beacon is still using it. * In case of two near updates of beacon: first as the result of set_tim and second as the result of a call from an application (e.g. hostapd). This patch fixes the race condition by rearranging the update logic and guarding rt2x00_intf->beacon->skb with a mutex.

We allocate skbs aligned to the cache line size. This requirement seems to have come from AR5210; when this was not done it seems sometimes we'd get bogus data. I'm also told it may have been a performance enhancement consideration. In the end I can't be sure we can remove this on new hardware so just keep this and start sharing it through ath.ko.

These issues stem from the complexities of managing two different types of packet commands for different hardware. - Unify code handling rx_phy_res in SKB or cached to eliminate redundancy and remove potential NULL pointer accesses - Replace magic number with proper constant - Optimize functions by moving early exit conditions before computation - Comment code and improve some variable names - Remove redundant computation in iwl_pass_packet_to_mac80211 by passing in the correct, already-computed arguments.

The global parameters should be set in iwl_mac_config and the local/varying parameters in iwl_ht_conf. This patch moves the channel width configuration from iwl_ht_conf to iwl_mac_config, and defers further cleanup of the local/global conflation for a later patch.

(mac80211 will correctly remove SGI support from station capabilities if the BSS does not permit it). This patch removes the short GI support bitfield from the global iwl_ht_info struct and properly uses per-station HT capabilities during rate selection.

This patch uses both the per-station GF support flag as well as the current BSS HT operation mode (non-GF stations present flag). Added the "ht_greenfield_support" field to struct iwl_cfg to replace the device-specific check in rs_use_green(). That check has been moved to iwlcore_init_ht_hw_capab().

In several places throughout the driver, this causes incorrect values to be interpreted as lengths when the field is improperly masked. In most situations the improper use is for debugging output, and simply results in an erroneous message, such as: [551933.070224] ieee80211 phy0: I iwl_rx_statistics Statistics notification received (480 vs -1367342620). which should read '(480 vs 484)'. In at least one case this could case bad things to happen: void iwl_rx_pm_debug_statistics_notif(struct iwl_priv *priv, struct iwl_rx_mem_buffer *rxb) { struct iwl_rx_packet *pkt = (struct iwl_rx_packet *)rxb->skb->data; IWL_DEBUG_RADIO(priv, "Dumping %d bytes of unhandled " "notification for %s:\n", le32_to_cpu(pkt->len), get_cmd_string(pkt->hdr.cmd)); iwl_print_hex_dump(priv, IWL_DL_RADIO, pkt->u.raw, le32_to_cpu(pkt->len) ); } EXPORT_SYMBOL(iwl_rx_pm_debug_statistics_notif); Given the rampant misuse of this field without proper masking throughout the driver (every use but one), this patch renames the field from 'len' to 'len_n_flags' to reduce confusion. It also adds the proper masking when this field is used as a length value. Signed-off-by: Daniel C Halperin Signed-off-by: Reinette Chatre Signed-off-by: John W.

=?UTF-8?q?G=C3=A1bor=20Stefanik?= Date: Fri, 14 Aug 2009 00:15:17 +0200 Subject: b43: LP-PHY: Implement channel switching for rev0/1/B2062 radio MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit -Move pdiv from lpphy_2062_init to struct b43_phy_lp. -Add channel table for the B2062 radio. -Add code for tuning the B2062 radio to channel. -Add error handling to op_switch_channel, and use it for both radios. Rev0/1/B2062 will now hopefully show some signs of life, though it won't work at full performance, as calibration is still missing. Signed-off-by: Gábor Stefanik Signed-off-by: John W.

To be able to simplify things, allow configure_filter to sleep, and add a new prepare_multicast callback that drivers that need the multicast address list implement. This new callback must be atomic, but most drivers either don't care or just calculate a hash which can be done atomically and then uploaded to the hardware non-atomically. A cursory look suggests that at76c50x-usb, ar9170, mwl8k (which is actually very broken now), rt2x00, wl1251, wl1271 and zd1211 should make use of this new capability.

This will leave the incorrect rssi in ANI. Having correct rssi in ANI fixes the connection stability at < 30dB rssi range. This patch removes the unncessary computation of average rssi over already valid average rssi. Also removes the redundant macros to find average rssi.

(And on both paths we are guaranteed to be the only user of the skb we are handling.) This allows removing all of the skb clone handling in the tx and tx reclaim paths, and eliminates error checks in both the tx and rx paths, simplifying the code a bit more.

And since waiting for command completion sleeps, we can't use a spinlock anyway. To fix mwl8k firmware command serialisation properly, we have the following requirements: - Some commands require that the packet transmit path is idle when the command is issued. (For simplicity, we'll just quiesce the transmit path for every command.) - There are certain sequences of commands that need to be issued to the hardware sequentially, with no other intervening commands. This leads to an implementation of a "firmware lock" as a mutex that can be taken recursively, and which is taken by both the low-level command submission function (mwl8k_post_cmd) as well as any users of that function that require issuing of an atomic sequence of commands, and quiesces the transmit path whenever it's taken.

If the device doesn't support remote wakeup, simple support based on up/down is provided. If the device supports remote wakeup, additional support for autosuspend while the interface is up is provided. This is done by queueing URBs in an anchor structure and waking the device up from a work queue on sending. Reception triggers remote wakeup. The last busy facility of the USB autosuspend code is used. To close a race between autosuspend and transmission, a counter of ongoing transmissions is maintained. Add #ifdefs for CONFIG_PM as necessary.

So packets take a slow path (lower priority) in firmware reducing performance. Firmware can cache limited number of remote unicast mac addresses for certain interval, if "dynamic mac learning" mode is enabled. Driver needs to enable this "mac learning" mode in firmware. Currently this is done through net device class sysfs entry, possibly this can also be done upon netlink notifications to from bridge.

During normal operation - stations are awake - the firmware refused to transmit broadcast frames and reported P54_TX_PSM_CANCELLED. But everything worked as soon as one station entered PSM. The reason: The stack sets IEEE80211_TX_CTL_SEND_AFTER_DTIM for outgoing broadcast frames as soon as a station is marked as sleeping. This flag triggers a path which will reroute these frames into p54's "content after beacon" queue, which is designed to cope with the demands for psm. This patch restores the old behavior. IEEE80211_TX_CTL_CLEAR_PS_FILT will once again be used to signalize the firmware to ignore the ps canceling for certain frames. Signed-off-by: Christian Lamparter Signed-off-by: John W.

Converted multiple calls to DBG_PRINT to single call form. Removed "s2io:" preface from DBG_PRINTs. The DBG_PRINT macro now emits a log level and is surrounded by a do {...} while (0) All s2io log output is now prefaced with KBUILD_MODNAME ": " via pr_fmt.

First, note that HT rates in the mac80211 rate table do not provide valid indices when ieee80211_get_tx_rate is called; the check to see if we could to abort a transmission early in iwl_tx_skb() would thus occasionally read invalid memory and occasionally stall transmission (if the erroneous byte was 0xff). We remove that code; the check wasn't valid anyway. Second, iwl_tx_cmd_build_rate() also called ieee80211_get_tx_rate to be used for sending management packets, which do not use the uCode station table. This patch refactors that function and adds comments to enhance legibility, replaces the call to ieee80211_get_tx_rate() with a direct lookup, and adds error handling in case the table entry is invalid.

However, iwl_hwrate_to_plcp_idx takes the MCS number and reduces it down to the range 0-8 (6 to 60 Mbps), removing the bits that signify multiply streams, HT40 Duplicate mode, or unequal modulation. This version is used for various internal purposes through the driver. Add the function iwl_hwrate_get_mac80211_idx, an alternate version which takes the rate and the band and returns the mac80211 index (MCS, for HT packets, and PLCP rate, for legacy packets).

So let's convert to use a succession of sleep levels when requesting to go to deeper sleeps (which can only happen with large DTIM intervals), using the succession values from power level three, which have the benefit of also having been tested extensively already. As a result, the automatic sleep level adjustment will now be mostly equivalent to power level three, except for the RX/TX timeouts and possibly using smaller sleep vectors to account for networking latency.

The entire function was being abused because it had multiple functions and the header length argument was somtimes used to align the header instead of the payload. Additionally there was a bug when inserting L2 padding that only the payload was aligned but not the header. This happens when the header wasn't aligned properly by mac80211, but rt2x00lib only moves the payload. A secondary problem was that when removing L2 padding during TXdone or RX the skb wasn't resized to the proper size. Split the function into seperate functions each handling its task as it should.

This consequently allows us to dynamically turn FCoE offload feature on or off upon incoming calls to ndo_fcoe_enable/disable. When this happens, FCoE offload features are enabled/disabled accordingly, and this is regardless of whether DCB being turned on or not.

Enabling VLAN filters (VFE) when the primary interface is brought up (per commit 78ed11a) has caused problems for some users who manage their systems using IPMI over a VLAN. This is because when the driver enables the VLAN filter, this same filter table is enabled for the management channel, and the table is initially empty, which means that the IPMI/VLAN packets are filtered out and not received by the BMC. This is a problem only on e1000 class adapters, as it is only on e1000 that the filter table is common to the management and host streams. With this change, filtering is only enabled when one or more host VLANs exist, and is disabled when the last host VLAN is removed. VLAN filtering is always disabled when the primary interface is in promiscuous mode, and will be (re)enabled if VLANs exist when the interface exits promiscuous mode. Note that this does not completely resolve the issue for those using VLAN management, because if the host adds a VLAN, then the above problem occurs when that VLAN is enabled. However, it does mean the there is no problem for configurations where management is on a VLAN and the host is not. A complete solution to this issue would require further driver changes. The driver would need to discover if (and which) management VLANs are active before enabling VLAN filtering, so that it could ensure that the managed VLANs are included in the VLAN filter table. This discovery requires that the BMC identifies its VLAN in registers accessible to the driver, and at least on Dell PE2850 systems the BMC does not identify its VLAN to allow such discovery. Intel is pursuing this issue with the BMC vendor. Signed-off-by: Dave Graham Signed-off-by: Jeff Kirsher Tested-by: Krzysztof Piotr Oledzki Signed-off-by: David S.

This can create a race in the DCB hardware blocks, and potentially hang the arbiters. Also, the Tx descriptor arbiter shouldn't be disabled when applying configuration changes; disabling this arbiter can cause a Tx hang.

When there is no link we first setup the link at 10G & 1G and then try to re-establish the link at highest speed 10G and thereby changing autoneg_advertised value to highest speed 10G. After connecting back the cable to a 1G link partner we never try 1G as autoneg advertised value is changed to link at 10G only. The following patch fixes the issue by properly initializing the autoneg_advertised value just before exiting from link setup routine.

While it is impossible for one function to interface with the wrong phy, that function still needs to know which MDIO bus address to use when interfacing with its own phy. This patch adds code to determine which MDIO bus address to use. Signed-off-by: Matt Carlson Reviewed-by: Benjamin Li Signed-off-by: David S.

If the high byte of the length has a different value than the dropped KISS byte users of clones of the skb may observe this as corruption. This was observed with by running listen(8) -a which uses a packet socket which clones transmit packets. The corruption will then typically be displayed for as a KISS "TX Delay" command for AX.25 packets in the range of 252..508 bytes or any other KISS command for yet larger packets. Fixed by using skb_cow to create a private copy should the skb be cloned. Using skb_cow also allows us to cleanup the old logic to ensure sufficient headroom in the skb. While at it, replace a return of 0 from bpq_xmit with the proper constant NETDEV_TX_OK which is now being used everywhere else in this function. Affected: all 2.2, 2.4 and 2.6 kernels.

Currently, FCoE has multiple Rx queues available, along with a redirection table, that helps distribute the I/O load across multiple CPUs based on the FC exchange ID. To make this the most effective, we need to provide the same layout of transmit queues to match receive.

We can do that defining rtnl_link_ops method, get_tx_queues(), called from rtnl_create_link() This new method gets num_tx_queues/real_num_tx_queues from lower device. macvlan_get_tx_queues() is a copy of vlan_get_tx_queues(). Because macvlan_start_xmit() has to update netdev_queue stats only (and not dev->stats), I chose to change tx_errors/tx_aborted_errors accounting to tx_dropped, since netdev_queue structure doesnt define tx_errors / tx_aborted_errors.

A0 parts are not production, but there are enough of these parts in the wild in test setups to warrant including workaround. A1 revision ASIC parts fix erratum.

Since firmware will be shared by all PCI functions that have different class drivers (NIC or FCOE or iSCSI), explicit hardware based serialization is required for initializing firmware. o Used global scratchpad register to maintain device reference count. Every probed pci function adds to ref count. o Implement timer (delayed work) for each pci func that checks firmware heartbit every 5 sec and detaches itself if firmware is dead. Last detaching function reloads firmware. Other functions wait for firmware init, and re-attach themselves. Heartbit is not supported by NX2031 firmware.

Internal clock is used for direct DTE-DTE connections and when the DCE doesn't provide it's own clock. This also depends on the oscillator frequency. Intel seems to have calculated the clock register settings for 33.33 MHz (66.66 MHz timer base). Their settings seem quite suboptimal both in terms of average frequency (60 ppm is unacceptable for G.703 applications, their primary intended usage(?)) and jitter. Many (most?) platforms use a 33.333 MHz oscillator, a 10 ppm difference from Intel's base. Instead of creating static tables, I've created a procedure to program the HSS clock register. The register consists of 3 parts (A, B, C). The average frequency (= bit rate) is: 66.66x MHz / (A + (B + 1) / (C + 1)) The procedure aims at the closest average frequency, possibly at the cost of increased jitter. Nobody would be able to directly drive an unbufferred transmitter with a HSS anyway, and the frequency error is what it really counts. I've verified the above with an oscilloscope on IXP425. It seems IXP46x and possibly IXP43x use a bit different clock generation algorithm - it looks like the avg frequency is: (on IXP465) 66.66x MHz / (A + B / (C + 1)). Also they use much greater precomputed A and B - on IXP425 it would simply result in more jitter, but I don't know how does it work on IXP46x (perhaps 3 least significant bits aren't used?). Anyway it looks that they were aiming for exactly +60 ppm or -60 ppm, while <1 ppm is typically possible (with a synchronized clock, of course). The attached patch makes it possible to set almost any bit rate (my IXP425 533 MHz quits at > 22 Mb/s if a single port is used, and the minimum is ca. 65 Kb/s). This is independent of MVIP (multi-E1/T1 on one HSS) mode. Signed-off-by: Krzysztof Hałasa Signed-off-by: David S.

This removes usage of the irq_lock spinlock, but introduces a new hardirq_lock, which is _only_ used for the PCI/SSB lowlevel hard-irq handler. Sleeping busses (SDIO) will use mutex instead.

After testing from James Ledwith it appeared that the calculated values caused a high amount of TX failures, and the values from the Legacy drivers were the most optimal to prevent TX failure due to excessive retries. The symptoms of this problem: - Rate control module always falls back to 1Mbs - Low throughput when bitrate was fixed Possible side-effects (not confirmed but highly likely) - Problems with DHCP - Broken connections due to lack of probe response This should fix at least: Kernel bugzilla reports: [13362], [13009], [9273] Fedora bugzilla reports: [443203] but possible some additional bugs as well.

It should be noted I have been told some FullMAC devices may not have worked with the SoftMAC driver but to date we have yet to recieve a single bug report regarding this.

Most prominent are WiFi and WiMAX based devices. However for userspace application it is important to classify these devices correctly and not only see them as Ethernet devices. The daemons like HAL, DeviceKit or even NetworkManager with udev support tries to do the classification in userspace with a lot trickery and extra system calls. This is not good and actually reaches its limitations. Especially since the kernel does know the type of the Ethernet device it is pretty stupid. To solve this problem the underlying device type needs to be set and then the value will be exported as DEVTYPE via uevents and available within udev. # cat /sys/class/net/wlan0/uevent DEVTYPE=wlan INTERFACE=wlan0 IFINDEX=5 This is similar to subsystems like USB and SCSI that distinguish between hosts, devices, disks, partitions etc. The new SET_NETDEV_DEVTYPE() is a convenience helper to set the actual device type. All device types are free form, but for convenience the same strings as used with RFKILL are choosen. Signed-off-by: Marcel Holtmann Signed-off-by: David S.
