Subject: mac80211: Fix behavior of ieee80211_open and ieee80211_close
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8b393f1dc76acbe65a97a4e51f8144f4a65fa1c9;p=linux-beck.git

mac80211: Fix behavior of ieee80211_open and ieee80211_close

This patch fixes:
- Incorrect calls to ieee80211_hw_config when the radiotap flag is set.
- Failure to actually unset the radiotap flag when all monitors are down.
- Failure to call ieee80211_hw_config after successful interface start.
