2011-04-26ath9k_hw: Fix Tx IQ Calibration hang issue in AR9003 chipsRajkumar Manoharan
On AR9003 chips, doing three IQ calibrations will possibly cause chip in stuck state. In noisy environment, chip could receive a packet during the middle of three calibrations and it causes the conflict of HW access and the eventual failure. It also causes IQ calibration outliers which results in poor Tx EVM. The IQ Cal procedure is after resetting the chip, run IQ cal 3 times per each cal cycle and find the two closest readings and average of two. The advantage of running Tx IQ cal more than once is that we can compare calibration results for the same gain setting over multiple iterations. Most of the cases the IQ failures were observed after first pass. For the AR9485 and later chips, Tx IQ Calibration is performed along with AGC cal. But for pre-AR9485 chips, Tx IQ cal HW has to be separated from the rest of calibration HW to avoid chip hang. After all calibrations are done in HW, we can start SW post-processing. By doing this way, we minimize the SW difference among all chips. The order of calibration (run IQ cal before other calibration) is also needed to avoid chip hang for chips before AR9485. This issue was originally observed with AR9382. During the issue kernel log was filled with following message ath: timeout (100000 us) on reg 0xa640: 0x00000001 & 0x00000001 != 0x00000000 ath: timeout (100000 us) on reg 0xa2c4: 0x00158dd9 & 0x00000001 != 0x00000000 ath: Unable to reset channel (2412 MHz), reset status -5 ath: Unable to set channel Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.

We need not wake up the chip even before mutex lock is acquired and also that it is required only if we are going to drain the txq.

2011-04-25mac80211: tear down BA sessions properly on suspendJohannes Berg
Currently, the code to tear down BA sessions will execute after queues are stopped, but attempt to send frames, so those frames will just get queued, which isn't intended. Move this code to before to tear down the sessions properly. Additionally, after stopping queues, flush the TX queues in the driver driver to make sure all the frames went out.

2011-04-25mwl8k: Reserve buffers for tx management framesNishant Sarmukadam
Since queues are not stopped anymore, management frames would be dropped if the corresponding tx queue is full. This can cause issues say when we want to setup an ampdu stream and action frames i.e addba requests keep getting dropped frequently. Fix this by reserving some buffers to allow management frames to go through in queue full conditions.

2011-04-25mwl8k: Do not stop tx queuesPradeep Nemavat
This is in preparation to support life time expiry of packets in the hardware to avoid head-of-line blocking where a slow client can hog a tx queue and affect the traffic to a faster client from the same queue. Time stamp the packets in driver to allow dropping them in the hardware if they are queued for more than 500ms. If queues are stopped, packets will be queued up outside the driver. Since we will be able to timestamp the packets only after they hit the driver, the timestamp will be less accurate since we cannot consider the time the packets spent in queues outside the driver. With this commit, to achieve accurate timestamping, the tx queues will not be stopped in normal conditions. The only scenarios where the queues will be stopped are when firmware commands are executing or if the interface is brought down. Now, we need to be prepared for a situation where packets hit the driver even after the tx queues are full. Drop all such packets in the driver itself.
