Use kcalloc or kzalloc rather than the combination of kmalloc and memset. Thanks coccicheck for detecting this. (http://coccinelle.lip6.fr/) Signed-off-by:

The scan code has a race that Michael reported he ran into, but it's easy to fix while at the same time simplifying the code. The race resulted in the following warning: ------------[ cut here ]------------ WARNING: at net/mac80211/scan.c:310 ieee80211_rx_bss_free+0x20c/0x4b8 [mac80211]() Modules linked in: [...] [<c0033edc>] (unwind_backtrace+0x0/0xe0) from [<c004f2a4>] (warn_slowpath_common+0x4c/0x64) [... backtrace wasn't useful ...] Reported-by:

It seems ath5k has issues receiving broadcast packets (ARPs) when using multiple STA interfaces associated with multiple APs. This patch ensures the NIC is always in PROMISC mode if there are more than 1 stations associated. Signed-off-by:

Usually H/W generate statistics notify once per about 100ms, but sometimes we can receive notify in shorter time, even 2 ms. This can be problem for plcp health and ack health checking. I.e. with 2 plcp errors happens randomly in 2 ms duration, we exceed plcp delta threshold equal to 100 (2*100/2). Also checking ack's in short time, can results not necessary false positive and firmware reset, for example when channel is noised and we do not receive ACKs frames or when remote device does not send ACKs at the moment. Patch change code to do statistic check and possible recovery only if 99ms elapsed from last check. Forced delay should assure we have good statistic data to estimate hardware state. Signed-off-by:

Now that all accesses to the data_queue structures is done via the specialized rt2x00queue_get_tx_queue function or via direct accesses, there is no need for the rt2x00queue_get_queue function anymore, so remove it. Signed-off-by:

In the spirit of optimizing the code to get the queue structure of TX queues, also optimize the code to get beacon queues. We can simply use the bcn queue field of the rt2x00_dev structure instead of using the rt2x00queue_get_queue function. Signed-off-by:

The ATIM queue is considered to be a TX queue by the drivers that support the queue. Therefore include support for the ATIM queue to the rt2x00queue_get_tx_queue function so that the drivers that support the ATIM queue can also use that function. Add the support in such a way that drivers that do not support the ATIM queue are not penalized in their efficiency. Signed-off-by:

Current code for the atim queue is strange, as it is considered in the rt2x00_dev structure as a second beacon queue. Normalize this by letting the atim queue have its own struct data_queue pointer in the rt2x00_dev structure. Signed-off-by:

The PCI device irqmask is locked by a spin_lock. Currently spin_lock_irqsave is used everywhere. To reduce the locking overhead replace spin_lock_irqsave in hard irq context with spin_lock and in soft irq context with spin_lock_irq. Signed-off-by:

When setting up multiple BSSIDs in AP mode on an rt2800pci device we previously used the STAs AID to select an appropriate key slot. But since the AID is per VIF we can end up with two STAs having the same AID and thus using the same key index. This resulted in one STA overwriting the key information of another STA. Fix this by simply searching for the next unused entry in the pairwise key table. Also bring the key table init in sync with deleting keys by initializing the key table entries to 0 instead of 1.

ieee80211_get_tx_rate is not valid for HT rates. Hence, restructure the TX desciptor creation to be aware of MCS rates. The generic TX desciptor creation now cares about the rate_mode (CCK, OFDM, MCS, GF). As a result, ieee80211_get_tx_rate gets only called for legacy rates. Acked-by:

HT and no-HT rt2x00 devices use a partly different TX descriptor. Optimize the tx desciptor memory layout by putting the PLCP and HT substructs into a union and introduce a new driver flag to decide which TX desciptor format is used by the device. This saves us the expensive PLCP calculation fOr HT devices and the HT descriptor setup on no-HT devices. Acked-by:

Newer devices like rt2800* own a hardware sequence counter and thus don't need to use a software sequence counter at all. Add a new driver flag to shortcut the software sequence number generation on devices that don't need it. rt61pci, rt73usb and rt2800* seem to make use of a hw sequence counter while rt2400pci and rt2500* need to do it in software.

This special case shouldn't happen very often. Only if a frame that is not intended to be aggregated ends up in an AMPDU _and_ was intended to be sent at a different MCS rate as the aggregate. Hence, using unlikely is justified. Signed-off-by:

In some cases (tx path for example) we don't need to check for non-tx queues in rt2x00queue_get_queue. Hence, introduce a new method rt2x00queue_get_tx_queue that is only valid for tx queues and use it in places where only tx queues are valid. Furthermore, this new method is quite short and as such can be inlined to avoid the function call overhead. This only converts the txdone functions of drivers that don't use an ATIM queue and the generic tx path. Signed-off-by:
