2013-10-29iwlwifi: mvm: BT Coex fix NULL pointer dereferenceEmmanuel Grumbach
When we disassociate, mac80211 removes the station and then, it sets the bss it unsets the assoc bool in bss_info. Since the firwmware wants it the opposite (first set the MAC context as unassoc, and only then, remove the STA of the API), we have a small period of time in which the STA in firmware doesn't have a valid ieee80211_sta pointer. During that time, iwl_mvm_vif->ap_sta_id, is still set to the STA in firmware that represent the AP.

2013-10-23wlcore: save last regdom configuration on stopEliad Peller

2013-10-23wlcore: fix started_vifs calculationEliad Peller
wlcore configures different dwell times according to number of active interfaces (in order to prevent hurting VO during scan). However, determining active vif only according to bss_conf->idle is not explicit enough, and might result in non-started vifs being counted as started as well (e.g. unassociated sta during sta). Fix it by checking for explicit conditions according to the vif type. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <luciano.coelho@intel.com>
2013-10-23wlcore: wakeup from ELP before starting recoveryBarak Bercovitz
Make sure the FW is awake when entering recovery. This is useful for reading the FW panic log and also some FW registers giving us crash report stats. We must do this before interrupts are disabled since we rely on an interrupt to complete the wakeup. If the wakeup fails, continue recovery normally. All read/writes will be blocked and won't do any harm.

2013-10-23wlcore: Allow stopping fw log in recoveryBarak Bercovitz
