When I tested commit 6539306b, I did not notice that loading an out-of-tree module turns off lockdep testing in kernel 3.2. For that reason, I missed the kernel WARNING shown below: The solution fixes the warning by partially reverting commit 6539306b.

When there is data available in dongle for driver to fetch, an interrupt will be triggered and both SDIO function 1 and 2 will be flagged by default in bcm4329. These two interrupt flags are identical and only need to be handled once. Since there is no way to turn off one flag from the dongle side, a dummy handler for function 2 interrupt is placed.

Following Rafal request, we verified that on "modern" CPUs using one or more workers is equivalent. Here is patch V3 that addresses the packet loss bug in the dma engine using only one worker. ------- This patch addresses a bug in the dma worker code that keeps draining packets even when the hardware queues are full. In such cases packets can not be passed down to the device and are erroneusly dropped by the code. This problem was already discussed here http://www.mail-archive.com/b43-dev@lists.infradead.org/msg01413.html and acknowledged by Michael. Number of hardware queues is now defined in b43.h (B43_QOS_QUEUE_NUM). Acknowledgements to Riccardo Paolillo <riccardo.paolillo@gmail.com> and Michele Orru <michele.orru@hotmail.it> Signed-off-by:

Scan type derived from IEEE80211_CHAN_PASSIVE_SCAN bit is a boolean flag representing passive scanning. We should not again compare it with driver specific macro MWIFIEX_SCAN_TYPE_PASSIVE to determine passive or active scan. We can also avoid the use of local variable by using the flag directly.

Currently code allows three (HT_AGG_MAX_RETRIES) unanswered addba requests. When this limit is reached aggregation is turned off for given TID permanently. This doesn't seem right: three requests is not that much, some 'blackout' can happen, but effect of it affects whole connection indefinitely. This patch increases number of retries to 15. Also, when there have been 3 or more retries it splits further retries apart by 15 seconds instead of sending them in very short period of time. Signed-off-by:
