2008-07-22netxen: cut-through rx changesDhananjay Phadke
NX3031 supports cut-through operation where ingress packets are directly dma'ed into host buffers to reduce latency. This requires larger dma buffers (2kb) and different alignemnt. The buffer posting logic is changed a bit. The free rx buffers are maintained in linked list, since the received reference handles can be out of order. However rx descriptors are still posted sequentially, indexed by producer. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-07-21mac80211_hwsim.c: fix: BUG: unable to handle kernel NULL pointer dereference ↵Ian Schram
at 0000000000000370 I was looking at this out of interest, but I'm in no way familiar with the code. Looks to me that the error handling code in mac80211_hwsim is awkward. Which leads to it calling ieee80211_unregister_hw even when ieee80211_register_hw failed. The function has a for loop where it generates all simulated radios. when something fails, the error handling will call mac80211_hwsim_free which frees all simulated radios who's pointer isn't zero. However the information stored is insufficient to determine whether or not the call to ieee80211_register_hw succeeded or not for a specific radio. The included patch makes init_mac80211_hwsim clean up the current simulated radio, and then calls into mac80211_hwsim_free to clean up all the radios that did succeed. This however doesn't explain why the rate control registration failed.. build tested this, but had some problems reproducing the original problem.

2008-07-21hdlcdrv: Fix CRC calculation.Micah Dowty
This is a trivial patch against the hdlcdrv module that fixes its CRC calculation. The finished CRC was overwriting the first two bytes of each packet rather than being appended to the end. I've tested this with 2.6.8 and 2.6.10-rc1, but hdlcdrv hasn't changed much recently so it should work with many other kernel versions.

2008-07-21atl1: Do not wake queue before queue has been started.David S. Miller
Based upon a bug report by Alexey Dobriyan, the patch is also tested by him and confirmed to fix the problem.

2008-07-20r8169: avoid thrashing PCI conf space above RTL_GIGA_MAC_VER_06Marcus Sundberg
The magic write to register 0x82 will often cause PCI config space on my 8168 (PCI ID 10ec:8168, revision 2. mounted in an LG P300 laptop) to be filled with ones during driver load, and thus breaking NIC operation until reboot. If it does not happen on first driver load it can easily be reproduced by unloading and loading the driver a few times. The magic write was added long ago by this commit: Author: François Romieu <romieu@fr.zoreil.com> Date: Sat Jan 10 06:00:46 2004 -0500 [netdrvr r8169] Merge of changes done by Realtek to rtl8169_init_one(): - phy capability settings allows lower or equal capability as suggested in Realtek's changes; - I/O voodoo; - no need to s/mdio_write/RTL8169_WRITE_GMII_REG/; - s/rtl8169_hw_PHY_config/rtl8169_hw_phy_config/; - rtl8169_hw_phy_config(): ad-hoc struct "phy_magic" to limit duplication of code (yep, the u16 -> int conversions should work as expected); - variable renames and whitepace changes ignored. As the 8168 wasn't supported by that version this patch simply removes the bogus write from mac versions <= RTL_GIGA_MAC_VER_06.

2008-07-17net: Use queue aware tests throughout.David S. Miller
This effectively "flips the switch" by making the core networking and multiqueue-aware drivers use the new TX multiqueue structures. Non-multiqueue drivers need no changes. The interfaces they use such as netif_stop_queue() degenerate into an operation on TX queue zero. So everything "just works" for them. Code that really wants to do "X" to all TX queues now invokes a routine that does so, such as netif_tx_wake_all_queues(), netif_tx_stop_all_queues(), etc. pktgen and netpoll required a little bit more surgery than the others. In particular the pktgen changes, whilst functional, could be largely improved. The initial check in pktgen_xmit() will sometimes check the wrong queue, which is mostly harmless. The thing to do is probably to invoke fill_packet() earlier. The bulk of the netpoll changes is to make the code operate solely on the TX queue indicated by by the SKB queue mapping. Setting of the SKB queue mapping is entirely confined inside of net/core/dev.c:dev_pick_tx(). If we end up needing any kind of special semantics (drops, for example) it will be implemented here. Finally, we now have a "real_num_tx_queues" which is where the driver indicates how many TX queues are actually active. With IGB changes from Jeff Kirsher. Signed-off-by: David S.

2008-07-17netdev: Allocate multiple queues for TX.David S. Miller
alloc_netdev_mq() now allocates an array of netdev_queue structures for TX, based upon the queue_count argument. Furthermore, all accesses to the TX queues are now vectored through the netdev_get_tx_queue() and netdev_for_each_tx_queue() interfaces. This makes it easy to grep the tree for all things that want to get to a TX queue of a net device. Problem spots which are not really multiqueue aware yet, and only work with one queue, can easily be spotted by grepping for all netdev_get_tx_queue() calls that pass in a zero index.

2008-07-17configfs: Allow ->make_item() and ->make_group() to return detailed errors.Joel Becker
The configfs operations ->make_item() and ->make_group() currently return a new item/group. A return of NULL signifies an error. Because of this, -ENOMEM is the only return code bubbled up the stack. Multiple folks have requested the ability to return specific error codes when these operations fail. This patch adds that ability by changing the ->make_item/group() ops to return ERR_PTR() values. These errors are bubbled up appropriately. NULL returns are changed to -ENOMEM for compatibility. Also updated are the in-kernel users of configfs. This is a rework of reverted commit 11c3b79218390a139f2d474ee1e983a672d5839a. Signed-off-by: Joel Becker <joel.becker@oracle.com>
