[MAC80211]: get STA after tx radiotap snipped
Johannes Berg noticed that in __ieee80211_tx_prepare() we try to get the STA from addr1 of the ieee80211 header when the radiotap header is actually still at the front of the packet. This patch defers doing that until the radiotap header is gone. Signed-off-by: Andy Green <andy@warmcat.com> Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
