mac80211: clean up eapol handling in TX path
The previous patch left only one user of the ieee80211_is_eapol() function and that user can be eliminated easily by introducing a new "frame is EAPOL" flag to handle the frame specially (we already have this information) instead of doing the (expensive) ieee80211_is_eapol() all the time. Also, allow unencrypted frames to be sent when they are injected. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
