mac80211: fix ibss join with fixed-bssid
When fixed bssid is requested when joining an ibss network, incoming beacons that match the configured bssid cause mac80211 to create new sta entries, even before the ibss interface is in joined state. When that happens, it fails to bring up the interface entirely, because it checks for existing sta entries before joining. This patch fixes this bug by refusing to create sta info entries before the interface is fully operational. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.
