cfg80211: introduce capability for 4addr mode
It's very likely that not many devices will support four-address mode in station or AP mode so introduce capability bits for both modes, set them in mac80211 and check them when userspace tries to use the mode. Also, keep track of 4addr in cfg80211 (wireless_dev) and not in mac80211 any more. mac80211 can also be improved for the VLAN case by not looking at the 4addr flag but maintaining the station pointer for it correctly. However, keep track of use_4addr for station mode in mac80211 to avoid all the derefs. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
