2013-04-03iwlwifi: mvm: set keepalive period regardless of PM stateAlexander Bondar2-3/+11
The firmware starts sending nulldata frames for keepalive immediately after association, regardless of power management state. The driver thus needs to configure keep alive period unconditionally.

2013-04-03iwlwifi: mvm: always send power table commandAlexander Bondar1-14/+12
The driver distinguishes between power management and device's power down enablement. Power management enablement depends both on driver's module power parameters and mac80211 decision. The device's power down depends only on driver's module power parameters. Change the driver to always send Power Table command to enable or disable both power management and device's power down.

2013-04-03iwlwifi: mvm: don't disable power management due to P2P deviceAlexander Bondar2-5/+17
Currently power management is supported only when only a single virtual interface is present. The driver verifies number of created interfaces and disables power management when multiple interfaces present. However, this rule does not extend to a P2P device that is handled differently in the firmware. If a P2P device is added power management can remain enabled.

mac80211 tells us when we need to dump the frames from the AGG queue instead of releasing them as single MPDUs. Being able to differentiate between the different cases (IEEE80211_AMPDU_TX_STOP_*) allows us to handle races better. When the station is removed, mac80211 asks to flush and removes the station right away. This allows to avoid a case where we still have frames in AGG queues, but the station has been remove already. Note that we can have frames on the shared queues, but this is not a problem: the station in the fw will be kept until all the frames on the shared queues have been drained.

2013-03-06iwlwifi: mvm: free AGG queue when we STA is removedEmmanuel Grumbach1-3/+3
When we stop an AGG session, we need to look at the sequence numbers in in the private area of the ieee80211_sta struct. This allows us to know is the queue is empty. To get access to this private area, we use fw_id_to_mac_id that maps sta_id (index of the STA in fw table) to ieee80211_sta. When the STA exists in fw, but not in mac80211, we set an ERR ptr in fw_id_to_mac_id. But if we first set an ERR ptr to fw_id_to_mac_id, and only then flush the queues, then we won't be able to access the sequence numbers in ieee80211_sta from the reclaim flow. This means that we will never be able to release an AGG queue when a station is deleted. So first, flush the queue. That will let the reclaim flow call iwl_mvm_check_ratid_empty which will disable the AGG queue as needed, and only then, remove the mapping in fw_id_to_mac_id.
