[Bug 580753] Re: ath9k module causing MIC challenge failures

[Jouni Malinen]

It looks like the issue is in ath9k reporting a one of the received
broadcast data frames (likely the first one after the group keys have
been set or are in the process of being set) as a decrypted frame even
when the data is not really correctly decrypted. mac80211 will then
process the frame and verify the Michael MIC value. This validation
fails because of bogus data in the frame.

ath9k key configuration and RX processing needs some further research to
figure out whether there is a clear issue somewhere or whether some kind
of workaround is needed to avoid reporting incorrect frames as decrypted
when a frame is received at the same time as the key is set.
