* iwlwifi: mvm: Change the settings of AP beacon timeIlan Peer2013-06-25
| | | | | | | | | | | | | | | | In case that an AP/GO interface is started while there is a station/P2P client associated, need to make sure that the AP/GO beacon time is far enough from the station's one in oder to allow the station to receive the DTIM beacons and the following traffic etc. To resolve this, when the AP is started, check if there is an active station interface, and guarantee that the AP/GO TBTT is far enough from the station one.

* iwlwifi: mvm: don't set the MCAST queue in STA's queue listEmmanuel Grumbach2013-06-11
| | | | | | | | | | The MCAST queue should be enabled after DTIM only. According to fw API, the MCAST must not be attached to any station, but should appear in the mcast_qid of the AP's mac context only.

* iwlwifi: mvm: correctly configure MCAST in AP modeEmmanuel Grumbach2013-06-04
| | | | | | | | | | | | | | | | The AP mode needs to use the MCAST fifo for the MCAST frames sent after the DTIM. This fifo needs to be configured with the same parameters as the VOICE FIFO. A separate SCD queue is mapped to this fifo - the cab_queue (cab stands for Content After Beacon). This queue isn't connected to any station, but rather to the MAC context. This queue should (and is already) be set as the MCAST queue - this is part of the of MAC context command.

* iwlwifi: mvm: Add support for connection monitor offloadHila Gonen2013-05-29
| | | | | | | | | | | | The firmware supports periodic keep alive and beacon monitoring, so advertise connection monitor offload capability by setting IEEE80211_HW_CONNECTION_MONITOR flag. Implement missed beacons notification handler. Call ieee80211_beacon_loss in case of missed beacons, so AP probing by mac80211 can be triggered.

* iwlwifi: mvm: add thermal throttling and CT killEytan Lifshitz2013-05-29
| | | | | | | | | | | | In order to avoid NIC destruction due to high temperature, CT kill will power down the NIC. To avoid this, thermal throttling will decrease throughput to prevent the NIC from reaching the temperature at which CT kill is performed.

* iwlwifi: mvm: Prevent setting assoc flag in MAC_CONTEXT_CMDAlexander Bondar2013-05-16
| | | | | | | | | | | | | | In the normal flow first MAC_CONTEXT_CMD for particular interface is never sent while associated. The exception is fw restart flow when resuming from suspend when WoWLAN is enabled. In this case successive "add" and "modify" MAC_CONTEXT_CMD commands may be sent with assoc flag set what cause FW mal functioning. To prevent this never set assoc flag in MAC_CONTEXT_CMD with action "add".

* | iwlwifi: mvm: don't read system time when modifying AP/GO MACJohannes Berg2013-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | When modifying a MAC, we update its beacon system time which is taken as a base to calculate TBTT. The firmware doesn't use the new timestamp because the time is never used after the MAC and broadcast station were added, but it is safer to not rely on this and avoids the overhead of reading the register every time the MAC is updated.

* iwlwifi: mvm: program DTIM timings properlyJohannes Berg2013-02-18
| | | | | | | | | | For the firmware to know when DTIM beacons arrive we have to program the DTIM time in TSF and system time in the MAC context.

* iwlwifi: mvm: don't delay the association until after beaconJohannes Berg2013-02-12
| | | | | | | | | | | | | If we haven't heard a beacon before we associate we can still start the association process and set the MAC in the firmware to associated only after having received a beacon with DTIM period by reacting to the new change flag (BSS_CHANGED_DTIM_PERIOD) from mac80211.
