Thanks! Applied. Please note that I changes some of driver_ops design
and did various cleanup changes, so it could be a good idea to re-test
this in your setup.

Hmm.. How exactly did you get this working? My tests with mac80211_hwsim
(after making it claim TDLS support) resulted in various kernel panics
(minstral does not exactly like the STA entry with no supported rates)
and cfg80211 rejecting the key configuration for the direct link. The
latter one is now fixed in wpa_supplicant (driver_nl80211.c).
I do have this working with mac80211_hwsim now, i.e., I do see frames
first going with FromDS/ToDS flags and then after TDLS setup without
those and finally after teardown, back to FromDS/ToDS flags and AP path.
However, this requires some kernel fixes (to be discussed on
