Subject: RFC: ieee80211: Spamming of log resulting from packets with ExtIV  not set
Date: Fri, 06 Apr 2007 18:53:34 -0500	[thread overview]
Message-ID: <4616DD7E.6010606@lwfinger.net> (raw)

Using bcm43xx-softmac, my log gets full of messages that look like:

Are there any objections to the following patch to eliminate these messages from TKIP and CCMP?
