@dalias @astraleureka @r @mirabilos @cr1901 @pinskia @joe @nilix No that's not what the doc says. it says "All mac80211 drivers". mac80211 is only for softmac devices.

fullmac devices (which are very common) typically do not support 4-addr mode. In fact, with a rapid grep, I could only find one fullmac driver (qtnfmac) that supports 4-addr, and only in STA mode.
