From: Ulrich Kunitz <kune@xxxxxxxxxxxxxx>
The ZD1211 supports the delivery of packets with a wrong CRC value
to the host. We switched that feature on in monitor mode, so that
incomplete packets were delivered.
This problem has been reported to bugzilla.kernel.org as bug 8152.
This patch fixes it for the mac80211 stack.
