Subject: [PATCH] hush noisy ieee80211 CCMP printks

From: Jason Lunz <[email-masked]>
Date: Sun, 4 Jun 2006 20:12:09 -0400

Don't swamp syslog with
CCMP: decrypt failed: STA=00:12:17:3a:e2:c7
and 
CCMP: replay detected: STA=00:12:17:3a:e2:c7 previous PN 000000000004 received PN 000000000004
messages.

These both seem to be completely normal in regular use, especially
'decrypt failed' whenever another wpa-using station on the same AP is
within range.

These events are still being counted in the statistics.
