mac80211: handle TX power per virtual interface
Even before channel contexts/multi-channel, having a single global TX power limit was already problematic, in particular if two managed interfaces connected to two APs with different power constraints. The channel context introduction completely broke this though and in fact I had disabled TX power configuration there for drivers using channel contexts. Change everything to track TX power per interface so that different user settings and different channel maxima are treated correctly. Also continue tracking the global TX power though for compatibility with applications that attempt to configure the wiphy's TX power globally. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
