2011-07-11rtlwifi: rtl8192cu: Fix duplicate if testLarry Finger
A typo causes routine rtl92cu_phy_rf6052_set_cck_txpower() to test the same condition twice. The problem was found using cppcheck-1.49, and the proper fix was verified against the pre-mac80211 version of the code.

2011-07-11libertas: fix handling of command timeout, completion and interruptionDaniel Drake
When commands time out, corruption ensues. As lbs_complete_command() is called without locking, the command node is mistakenly freed twice. Also fixed up locking here in a few other places. The nature of command timeout may be that the card didn't even acknowledge receipt of the request. Detect this case and reset dnld_sent so that other commands don't hang forever. When cmdnodes are moved between the free list and the pending list, their list heads should be reinitialized. Fixed this. Sometimes commands are completed without actually submitting them or removing them from cmdpendingq. We must remember to remove them from cmdpendingq in these cases, so handle this in lbs_complete_command(). Harmless signals generated during suspend/resume were interrupting lbs_cmd. Convert to an uninterruptible sleep to avoid this. lbs_thread must be woken up every time there is some new work to do. I found that when 2 commands are queued, ther completion of the first command would not wake up lbs_thread to submit the second. Poke lbs_thread at the end of lbs_complete_command() to fix this.

2011-07-11iwlagn: Enable/disable PS poll based on RSSI and BT coex traffic stateMeenakshi Venkataraman
WiFi throughput drops drastically when BT is turned on, BT and WiFi are simultaneously transmitting/receiving traffic. This is particularly true when BT has higher priority over WiFi, and hence the device defers TX frames. The AP assumes that the channel is bad and reduces the data rate, implying longer airtime, which exacerbates the problem further, resulting ultimately in what is popularly called the "death-spiral" phenomenon. The use of PS-poll in such scenarios guarantees a low but consistent throughput. Since the death-spiral phenomenon is observed only when the RSSI is low, use PS-poll only when RSSI is low and disable when high, with a known hysterisis. This feature specifies the high and low thresholds and implements the callbacks registered with mac80211, which will be called when threshold events occur. iwlwifi: dynamic pspoll: optimize rssi monitor code Signed-off-by: Meenakshi Venkataraman <meenakshi.venkataraman@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.
