2008-03-13rt2x00: Add suspend/resume handlers to rt2x00rfkillIvo van Doorn
Add suspend/resume handlers to rt2x00rfkill to have it stop the input-polldev and prevent it from calling rt2x00 during suspend period. This could lead to a NULL pointer fault when rt2x00 suspended, but polldev send a request, because the csr_addr is NULL. Also don't let the rfkill allocation/registration block the initialization of the entire device. Just print a warning and continue as if nothing happened.

2008-02-28rt2x00: Fix rt2x00lib_reset_link_tuner()Ivo van Doorn
rt2x00lib_reset_link_tuner() can be called from within the link tuner itself. This means that it should _not_ call rt2x00lib_stop_link_tuner() since that will cause the thread to hang. Reorder the things that should be done during a link tuner reset and during a link tuner start. Also make antenna tuning the last step of the link tuner since it could possibly reset some statistical information which we need for average calculation.

2008-02-28rt2x00: Don't switch to antenna with low rssiIvo van Doorn
When rssi_a > rssi_b is true and the current antenna was already antenna A, then rt2x00 incorrectly jumped to antenna B. Also don't configure the antenna when there has been no change in the antenna setup. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-02-28rt2x00: Add link tuner safe RX toggle statesIvo van Doorn
This adds 2 new states which both are used to toggle the RX. These new states are required for usage inside the link tuner thread, because the normal RX toggling will stop the link tuner thread. While it is possible that the link tuner thread itself is the caller of the RX toggle (when using software antenna diversity). Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-02-28rt2x00: Fix antenna diversityIvo van Doorn
Fix 2 issues in antenna diversity selection. 1) the following statement will always return true. if ((rssi_curr - rssi_old) > -5 || (rssi_curr - rssi_old) < 5) It is cleaner to check if the absolute value is smaller then 5. 2) Only enable software diversity when default antenna setup indicates support for it.

2008-01-28rt2x00: Fix queue_idx initializationIvo van Doorn
For TX rings the queue_idx should start at IEEE80211_TX_QUEUE_DATA0 and for each followup ring this index needs to be increased. For the RX ring the queue_idx should be set to 0. We don't need to initialize the tx_params. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28rt2x00: Data and desc pointer initializationIvo van Doorn
rt2500usb and rt73usb data and desc pointer initialization was incorrect because it was using uninitialized variables to determine the length. In addition rt2500usb used skb_pull and removed the ieee80211 from each received frame instead of using skb_trim to remove the device descriptor from the frame. Finally this also fixes the descriptor override when 4 byte aligning occured. We still need a completely valid descriptor when using the TX/RX dumping capabilities in debugfs.

2008-01-28mac80211: add unified BSS configurationJohannes Berg
This patch (based on Ron Rindjunsky's) creates a framework for a unified way to pass BSS configuration to drivers that require the information, e.g. for implementing power save mode. This patch introduces new ieee80211_bss_conf structure that is passed to the driver via the new bss_info_changed() callback when the BSS configuration changes. This new BSS configuration infrastructure adds the following new features: * drivers are notified of their association AID * drivers are notified of association status and replaces the erp_ie_changed() callback. The patch also does the relevant driver updates for the latter change.

2008-01-28mac80211: dont use interface indices in driversJohannes Berg
This patch gets rid of the if_id stuff where possible in favour of a new per-virtual-interface structure "struct ieee80211_vif". This structure is located at the end of the per-interface structure and contains a variable length driver-use data area. This has two advantages: * removes the need to look up interfaces by if_id, this is better for working with network namespaces and performance * allows drivers to store and retrieve per-interface data without having to allocate own lists/hash tables Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2008-01-28rt2x00: Correctly initialize data and desc pointerIvo van Doorn
rt2500usb and rt73usb store the descriptor in different places. This means we should move the initialization of the 2 pointers to the driver callback function fill_rxdone(). Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-01-28rt2x00: Move init_txring and init_rxring into rt2x00libIvo van Doorn

2008-01-28rt2x00: Determine MY_BSS from descriptorIvo van Doorn

2008-01-28rt2x00: Cleanup write_tx_desc() argumentsIvo van Doorn

Linville <linville@tuxdriver.com>
2008-01-28rt2x00: Move packet filter flagsIvo van Doorn
The packet filter flags don't belong in the interface structure because they are device based instead of interface based. So move the filter fields out of struct interface and into rt2x00_dev. Additionally we shouldn't change the filter based on the working mode, if such a thing is needed than mac80211 should have done that.

2008-01-28rt2x00: Move start() and stop() handlers into rt2x00lib.cIvo van Doorn
suspend & resume was broken since it called rt2x00mac_start() and rt2x00mac_stop() which would fail to execute because the DEVICE_PRESENT flag was not set. Move the start and stop handlers into rt2x00lib.c which are called from rt2x00mac_start() and rt2x00mac_stop() after they have checked the DEVICE_PRESENT flag, while suspend and resume handlers can directly call those functions.

2008-01-28rt2x00: Only set the TBCN flag when the interface is configured to send beacons.Ivo van Doorn
These flags used to be fixed to one in rt2500pci_config_type, which caused the beacon timer interrupt to fire. This would lead to rt2x00lib_beacondone adding work which called rt2x00lib_beacondone_scheduled which called ieee80211_beacon_get which printed an error about not having any beacon data. With this patch, these interrupts are only generated when the interface is configured to send beacons.

2008-01-28rt2x00: Always call ieee80211_stop_queue() when return NETDEV_TX_BUSYIvo van Doorn
Apparently it was possible that ieee80211_stop_queue() was not full while NETDEV_TX_BUSY was being reported back. I think that is what causing the WARN_ON(). This moves all calls to ieee80211_stop_queue() in rt2x00mac.c where it is easier to determine if the queue should be halted. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-01-28rt2x00: Only update rssi average approximation on receiving beacon frames.Mattias Nissler
Restrict rssi average updating to beacon frames of the bssid the interface is associated with. Without this restriction, strong signals belonging to other BSS, e.g. beacon frames coming from a nearby AP, would cause incorrectly high rssi approximation values. This would then cause the link tuner to reduce sensitivity, resulting in transmissions from the BSS associated to to be missed.

2008-01-28rt2x00: Add TX/RX frame dumping facilityIvo van Doorn
This adds TX/RX frame dumping capabilities through debugfs. The intention is that with this approach debugging of rt2x00 is simplified since _all_ frames going in and out of the device are send to debugfs as well along with additional information like the hardware descriptor.

Add a flag to struct txdata_entry_desc that specifies whether an ack for the frame is to be expected. Use this flag to set the ACK bit in the tx descriptor.

2008-01-28rt2x00: Place mutex around USB register accessAdam Baker
There is a buffer, csr_cache which is used to hold copies of data being passed to the USB stack which can get corrupted if multiple threads attempt to access CSR registers simultaneously. There is also the possibility if multiple threads try to access BBP or RF registers for the multiple USB operations needed to get interleaved leading to incorrect results. This patch introduces a mutex to prevent such simultaneous access. The interleaved access problem may also affect the PCI devices but if so that will be handled in a follow-up patch.
