To summarise, a WPA-TKIP managed connection stops passing traffic and
the kernel log shows the message "WPA: Group rekeying".  This apparently
doesn't happen if the connection is in heavy use at the time or with
module parameter swcrypto=1.  WPA2 is not affected either.

I think this is due to my patch "iwlagn: rewrite HW crypto" which
accidentally broke key *removal* (of all things), which causes issues
when the first GTK is removed on the second rekeying.

This patch
[...]h=5dcbf480473f6c3f06ad2426b7517038a2a18911

should fix it. Wey has sent it to John

[...]

it's also marked for stable.

Shawn Thompson (cc-ed) tested the patch against 3.2.9 and 3.3-rc6 and
found it to work[1].  What can interested people do to help usher this
into mainline?

(To recap, this was a regression introduced between 3.0 and 3.1,
presumably by v3.1-rc1~24^2~10^2^2~37.)

Thanks,
Jonathan
