mac80211: fix BSS info reconfiguration
When reconfiguring an interface due to a previous hardware restart, mac80211 will currently include the new IBSS flag on non-IBSS interfaces which may confuse drivers. Instead of doing the ~0 trick, simply spell out which things are going to be reconfigured. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
