Since the update from linux 3.2.1 to 3.2.2, dhcp stopped working on
some APs on my laptop with an AR9285 Wireless card.

dhcp works fine on an open wifi network but receives no response on a
wep network I use. I haven't been able to test it on a third network
for now.
Reverting to 3.2.1 solved the issue which is still there in the latest
git revision as of today.

DHCPDISCOVER requests are still sent but no ACK is received (nothing
in Wireshark).

dhcp failure may be one particular instance of the problem but I
haven't been able to connect with a static ip (my ap doesn't like it)
so this is the
only result I know.
