Conflicts: MAINTAINERS drivers/net/wireless/iwlwifi/pcie/trans.c The iwlwifi conflict was resolved by keeping the code added in 'net' that turns off the buggy chip feature. The MAINTAINERS conflict was merely overlapping changes, one change updated all the wireless web site URLs and the other changed some GIT trees to be Johannes's instead of John's.

2012-06-11ath9k_hw: Initvals update for AR9462Sujith Manoharan
MSI is enabled by default for most of the 4th generation chips. Add this for AR9462 - this fixes PowerSave operation, the chip was not entering Network-Sleep mode earlier. With proper powering down of the MAC now, power consumption in associated state is reduced considerably. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.

2012-06-11mwifiex: scan less channels per scan command to improve Tx trafficAmitkumar Karwar
Currently 4 channels are scanned per scan command. if scan request is issued by user during Tx traffic, radio will be out of channel for "4 * per_chan_scan_time" for each scan command and will not be able to receive Rx packets. This adds delay in data traffic. We can minimize it by reducing number of channels scanned per scan command in this scenario. We can not always scan 1 channel per scan command due to limitation of number of command buffers. So we add code to decide number of channels scanned per scan command in associated state.

2012-06-11mwifiex: fix simultaneous scan and Tx traffic problemAmitkumar Karwar
If scan operation is started when Tx traffic is already running, driver locks Tx queue until it gets completed. With this logic there is a delay for Tx packets. This patch implements new approach to give Tx path higher priority in this case. Driver internally sends multiple synchronous scan commands to firmware when scan is requested by user. Now we will make sure that Tx queue is empty everytime before sending next scan command. If Tx queue isn't empty scan command will be postponsed by 20msec. This rule will be followed until Tx queue becomes empty or timeout of 1 second happens. In case of timeout scan operation will be aborted.

2012-06-11mwifiex: shorten per channel scan timeBing Zhao
Currently the scan time per channel for active scanning is set to 200ms. It takes quite a while to finsh scanning on all channels, especially with a dual band configuration. Change the per channel scan time settings to the following values: passive scan: 110ms active scan: 30ms specific scan: 30ms Above settings have been tested on x86 and arm platforms.

2012-06-08iwlwifi: don't mess up the SCD when removing a keyEmmanuel Grumbach
When we remove a key, we put a key index which was supposed to tell the fw that we are actually removing the key. But instead the fw took that index as a valid index and messed up the SRAM of the device. This memory corruption on the device mangled the data of the SCD. The impact on the user is that SCD queue 2 got stuck after having removed keys. The message is the log that was printed is: Queue 2 stuck for 10000ms This doesn't seem to fix the higher queues that get stuck from time to time.
