2012-05-22cw1200: Avoid sleeping on TX lock for more than 1.5 sec.Dmitry Tarnyagin
The patch protects against possible timeout in system suspend code. It implements timestamps for TX frames, and do not wait more than 1.5 sec in total since the oldest frame is sent to firmware. Firmware has to reply within this interval, otherwise driver commits suicide by terminating device communication thread.

Fixes a very rare BUG_ON in cw1200_tx by reserving extra queue slots for an overflow scenario. It's possible for a parallel TX to happen when in softap since there are two interfaces (wlan1 and mon.wlan1). Softirq may switch from one thread to another asynchronously. In such a case __ieee80211_tx may call driver tx callback just before a queue is locked.

2012-05-22cw1200: Enable REPORTS_TX_ACK_STATUS HW CAP bit.Dmitry Tarnyagin
High power consumption was reported with a particular AP. 1. IEEE80211_HW_REPORTS_TX_ACK_STATUS bit was not set in the driver, so direct probe responses were used for probing BSS after wakeup instead of more efficient null-frame requests. 2. The AP does not answer to direct probes at all. 3. Both stack (explicitly) and firmware (implicitly) configure IEEE PS after exiting scan. And they were doing it in a right opposite way. Sometimes device entered full-power state instead of IEEE PS state. The fix changes probing policy from probe requests to null frames.

Firmware may report exit of GO absence interval as a start: unicast suspend/resume notification with link id equals to 0. This case was not handled correctly. The patch implements (costly!) solution for that. Start: unicast indication resets power save states of all connected STAs, and driver performs an attempt to deliver buffered frames for them. For STAs in powersave frirmware rejects frames, syncronizing power state. The solution is really costly and can be used as a workaround in short time prospective. It's much better if firmware reports proper link id in the suspend/resume notification.

2012-05-22cw1200: Fixes for multicast delivery in AP/UAPSD mode.Dmitry Tarnyagin
* Powersave state of UAPSD STA must be explicitly forced to "PS", mac80211 stack provides no PS notification for these STAs. * Mcast timeout was wrongly triggered due to wrongly used mod_timer call. * tx_multicast flag was not reset in case of successful mcast delivery. * FW may requeue a multicast frame. To deliver the frame, driver should start a new multicast session: set AID0 and wait for suspend/resume indication. * Due to a race with requeue a multicast-stop work could override a started multicast sequence in progress.
