2011-09-20rtlwifi: Combine instances of RTL_HAL_IS_CCK_RATE macros.Larry Finger
Three drivers, rtl8192ce, rtl8192cu and rtl8192de, use the same macro to check if a particular rate is in the CCK set. This common code is relocated to a common header file. A distinct macro used by rtl8192se with the same name is renamed. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2011-09-19mac80211: Fix regression on queue stop during 2040 bss changeRajkumar Manoharan
The commit "mac80211: stop tx before doing hw config and rate update" stops the tx queue and call drv_flush so frequently whenever a beacon got received with 11n htcap. This leads to massive "Failed to stop TX DMA" logspam on embedded hw. So the queue stop and flush should be called if and only if there is a change in the channel type.

2011-09-19iwlagn: do not use interruptible waitsJohannes Berg
Since the dawn of its time, iwlwifi has used interruptible waits to wait for synchronous commands and firmware loading. This leads to "interesting" bugs, because it can't actually handle the interruptions; for example when a command sending is interrupted it will assume the command completed fully, and then leave it pending, which leads to all kinds of trouble when the command finishes later. Since there's no easy way to gracefully deal with interruptions, fix the driver to not use interruptible waits. This at least fixes the error iwlagn 0000:02:00.0: Error: Response NULL in 'REPLY_SCAN_ABORT_CMD' I have seen in P2P testing, but it is likely that there are other errors caused by this.

2011-09-19iwlagn: unmap cmd queue's tfds as BIDIEmmanuel Grumbach
If the driver is unloaded while there is still a host command in flight, its tfd will be freed by iwl_tx_queue_free. This function is called for both types of queues: Tx queues and cmd queue. This didn't take in count the fact that in Tx queues, tfds are mapped as TO_DEVICE (besides the first TB), whereas in cmd queue, all TBs are mapped as BIDI. Hence, tx_queue_free unmapped the second (and higher) TB of each tfd in the cmd queue as TO_DEVICE, whereas they must be freed as BIDI. This means that if a multi TFD is in flight while we unload the driver (which is quite unlikely but can happen), we will get the warning below. This patch fixes this.
