Subject: [PATCH] p54: fix beacon template dtim IE corruption
Date: Sat, 4 Jul 2009 18:24:07 +0200	[thread overview]
Message-ID: <200907041824.07655.chunkeey@web.de> (raw)

This patch fixes a regression that sneaked in with 
"[PATCH] p54: re-enable power save feature".
When p54_beacon_format_ie_tim was divided up
and rewritten to use skb_* macros.
