Bisected 3.9 regression for iwl4965 connection problem to 1672c0e3

After building 3.9 for my HP/Compaq 2510p laptop, the wireless (iwl4965)
would seemingly no longer connect. Actually, it seems that it *will*
eventually, where that is somewhere between 4 and 21+ retries (from KDE
network manager). Going back to 3.8 (and earlier) and the problem goes
away. (All on Fedora 18, fwiw, but I don't think that's significant).

I bisected the problem to:

commit 1672c0e31917f49d31d30d79067103432bc20cc7
Author: Johannes Berg <johannes.berg@intel.com>
Date: Tue Jan 29 15:02:27 2013 +0100

mac80211: start auth/assoc timeout on frame status

but I can't (easily) revert that in 3.9 (maybe I can in -rc1 or
something? haven't tried that)

What more information is needed from me? I may still mess around with
trying to revert that patch just to nail it down for sure, but two
separate bisection exercises ended up at the same place.

There are a few traps for the unwary if anyone else ends up bisecting
in through here -- the first bisection (3.8 - 3.9-rc1) ran into an IPv6
build error along the way, which I "fixed" by configuring it out --
also, the amount of retries goes from *many* (15-21+) to relatively few
(4) somewhere in there, which confused me and led to the second
bisection (3.8-3.9) ...
