2011-10-03libertas: detect TX lockups and reset hardwareDaniel Drake
Recent patches added support for resetting the SD8686 hardware when commands time out, which seems to happen quite frequently soon after resuming the system from a Wake-on-WLAN-triggered resume. At http://dev.laptop.org/ticket/10969 we see the same thing happen with transmits. In this case, the hardware will fail to respond to a frame passed for transmission, and libertas (correctly) will block all further commands and transmissions as the hardware can only deal with one thing at a time. This results in a lockup while the system waits indefinitely for the dead card to respond. Hook up a TX lockup timer to detect this and reset the hardware.

2011-10-03mwifiex: correct AMSDU aggregation checkAmitkumar Karwar
The commit "mwifiex: remove list traversal.."(fcf2176c87..) wrongly modifies AMSDU aggregation check. Due to this even though packet size for iperf traffic is already large, we unnecessarily try to aggregate them which adds some delay. If Tx iperf is started on UUT for 30 seconds, UUT keeps sending Tx packets for few more seconds. That commit is reverted to fix the problem. Also, MIN_NUM_AMSDU check is moved inside the loop to optimize the loop.

2011-09-30mac80211: implement uAPSDJohannes Berg
Add uAPSD support to mac80211. This is probably not possible with all devices, so advertising it with the cfg80211 flag will be left up to drivers that want it. Due to my previous patches it is now a fairly straight-forward extension. Drivers need to have accurate TX status reporting for the EOSP frame. For drivers that buffer themselves, the provided APIs allow releasing the right number of frames, but then drivers need to set EOSP and more-data themselves. This is documented in more detail in the new code itself. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-09-30mac80211: let drivers inform it about per TID buffered framesJohannes Berg
For uAPSD implementation, it is necessary to know on which ACs frames are buffered. mac80211 obviously knows about the frames it has buffered itself, but with aggregation many drivers buffer frames. Thus, mac80211 needs to be informed about this. For now, since we don't have APSD in any form, this will unconditionally set the TIM bit for the station but later with uAPSD only some ACs might cause the TIM bit to be set. ath9k is the only driver using this API and I only modify it in the most basic way, it won't be able to implement uAPSD with this yet. But it can't do that anyway since there's no way to selectively release frames to the peer yet. Since drivers will buffer frames per TID, let them inform mac80211 on a per TID basis, mac80211 will then sort out the AC mapping itself.

2011-09-27iwlagn: fix dangling scan requestJohannes Berg
If iwl_scan_initiate() fails for any reason, priv->scan_request and priv->scan_vif are left dangling. This can lead to a crash later when iwl_bg_scan_completed() tries to run a pending scan request. In practice, this seems to be very rare due to the STATUS_SCANNING check earlier. That check, however, is wrong -- it should allow a scan to be queued when a reset/roc scan is going on. When a normal scan is already going on, a new one can't be issued by mac80211, so that code can be removed completely. I introduced this bug when adding off-channel support in commit 266af4c745952e9bebf687dd68af58df553cb59d.
