* iwlwifi: mvm: Implement CQM offloadingAndrei Otcheretianski2013-08-16
| | | | | | | | | | | | Use beacon statistics notification to track RSSI. Notify mac80211 when the tresholds are crossed. The roaming treshold is configured to be equal to cqm_thold. If the beacon filtering command is not supported by fw fall back and use mac80211 mechanism.

* iwlwifi: mvm: refactor resume from WoWLAN codeJohannes Berg2013-08-16
| | | | | | | | | | | To be able to add more logic to the resume code, refactor it a bit, moving some status checking/reporting logic into a new function. The locking becomes a bit odd (one of the new functions now unlocks the mutex) but this will be required to call new mac80211 APIs in there later.

* iwlwifi: mvm: fix debugfs restart if fw_restart is disabledEran Harary2013-07-31
| | | | | | | | | | | | | | If fw_restart is disabled, using the fw_restart debugfs file will enable fw_restart and then send the failing command, but this still frequently fails restart because it resets fw_restart afterwards and is thus racy.

* iwlwifi: mvm: reprobe device on firmware error during restartJohannes Berg2013-07-31
| | | | | | | | | | | | | | | If we get a firmware error during restart, we currently abandon any hope and simply fail, getting stuck until the driver is reloaded. Unfortunately, there isn't really much else we can do since restart will likely continue to fail, and asking mac80211 for disconnection just causes more error. To allow the user to at least set up the device again completely from scratch, reprobe the device and in doing so completely destroy any mac80211/driver state.
