net80211/driver LORs: http://wiki.freebsd.org/WiFiDebugging

.. so the first LOR is between node table lock and comlock - the
former in ieee80211_timeout_stations() and the latter in
ieee80211_set_tim().

So, something is holding the comlock when the node table lock is being
grabbed. Where is that happening? Would someone like to tackle that
particular issue?

Eg, what about printing out a witness backtrace if the comlock is held
when the node table lock is held? And vice versa? Just to try and
figure out who is holding things incorrectly?
