Subject: regression, 3.2.2 stable: ath9k won't associate anymore

Hi,

commit "b4a82a0 ath9k_hw: fix interpretation of the rx KeyMiss flag"
caused my card to stop associating with the router.
Reverting it fixes the issue. Encryption is WEP, if that matters; I
haven't tried others.

The device is "10:00.0 Network controller: Atheros Communications Inc.
AR9287 Wireless Network Adapter (PCI-Express) (rev 01)"

excerpt from dmesg before the revert:

The issue is WEP specific, a fix has been found and confirmed. I'll
submit it for inclusion soon.
