From c9308b06c049a107edfbd4e5271771564eb6024d Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Wed, 27 Sep 2006 03:50:31 +0100 Subject: [PATCH] ieee80211: Move IV/ICV stripping into ieee80211_rx This patch adds a host_strip_iv_icv flag to ieee80211 which indicates that ieee80211_rx should strip the IV/ICV/other security features from the payload. This saves on some memmove() calls in the driver and seems like something that belongs in the stack as it can be used by bcm43xx, ipw2200, and zd1211rw I will submit the ipw2200 patch separately as it needs testing. This patch also adds some sensible variable reuse (idx vs keyidx) in ieee80211_rx Signed-off-by: Daniel Drake Acked-by: Johannes Berg Signed-off-by: John W.
