>Description:
	I have an application that attempts to read from a tap device, and
	tunnel 802.11 packets over IP. Unfortunately, 802.11 beacons aren't
	passed to the tap device, so I can't replicate the wireless packets
	on the other side.
>How-To-Repeat:
	ifconfig bridge0 create
	ifconfig tap0 create
	ifconfig tap0 up
	brconfig bridge0 add "${WINTF}"
	brconfig bridge0 add tap0
	brconfig bridge0 -learn "${WINTF}"
	brconfig bridge0 discover "${WINTF}"
	brconfig bridge0 -learn tap0
	brconfig bridge0 discover tap0
	brconfig bridge0 flush
	brconfig bridge0 up

	Then attempt to read from /dev/tap0, notice that you won't see any
	802.11 beacons.
>Fix:
	Not sure yet.
