cfg80211/mac80211: allow any interface to send channel switch notifications
For multi-vif channel switches, we want to send NL80211_CMD_CH_SWITCH_NOTIFY to the userspace to let it decide whether other interfaces need to be moved as well. This is needed when we want a P2P GO interface to follow the channel of a station, for example. Modify the code so that all interfaces can send CSA notifications. Additionally, send notifications for STA CSA as well. Signed-off-by: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
