The missing patch is shown below. This patch was entitled "[PATCH] bcm43xx: Readd dropped
assignment" and submitted to wireless-2.6 by Daniel Drake on 10/17/06, but it seems to have fallen
through the cracks. It is a fix to a patch entitled "[PATCH] ieee80211: Move IV/ICV stripping into
ieee80211_rx" also submitted by Daniel Drake on 9/26/2006.

NOTE to maintainers: This problem affects BOTH wireless-2.6 and 2.6.19-rcX-mmY. At present, the
"Move IV/ICV" patch has not been incorporated into 2.6.19-rcX and it is OK.

In the patch sent by Daniel Drake under the title "[PATCH] ieee80211: Move
IV/ICV stripping into ieee80211_rx", a needed line was accidentally removed.
As my current copy of wireless-2.6.git does not contain this line, I am
(re)submitting a patch to restore that line.
