mac80211: Reset MBSSID parameters upon connection
[ Upstream commit86af062f40
] Currently MBSSID parameters in struct ieee80211_bss_conf are not reset upon connection. This could be problematic with some drivers in a scenario where the device first connects to a non-transmit BSS and then connects to a transmit BSS of a Multi BSS AP. The MBSSID parameters which are set after connecting to a non-transmit BSS will not be reset and the same parameters will be passed on to the driver during the subsequent connection to a transmit BSS of a Multi BSS AP. For example, firmware running on the ath11k device uses the Multi BSS data for tracking the beacon of a non-transmit BSS and reports the driver when there is a beacon miss. If we do not reset the MBSSID parameters during the subsequent connection to a transmit BSS, then the driver would have wrong MBSSID data and FW would be looking for an incorrect BSSID in the MBSSID beacon of a Multi BSS AP and reports beacon loss leading to an unstable connection. Reset the MBSSID parameters upon every connection to solve this problem. Fixes:78ac51f815
