[patch 03/48] mac80211: restrict to AP in outgoing interfaceheuristic

[Greg KH]

2.6.28-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Johannes Berg <johannes@xxxxxxxxxxxxxxxx>

commit f1b33cb1c25ac476cbf22783f9ca2016f99648ed upstream.

We try to find the correct outgoing interface for injected frames
based on the TA, but since this is a hack for hostapd 11w, restrict
the heuristic to AP mode interfaces. At some point we'll add the
ability to give an interface index in radiotap or so and just
remove this heuristic again.
