	I have two bce interfaces which are aggregated using lagg and LACP
	to a CISCO switch. The above commit stops this working - the
	machine appears to come up fine, and the interfaces are in the
	usual state of ACTIVE,COLLECTING,DISTRIBUTING, but no network
	communication with the machine is possible.


	A csup of the code with date=2009. works, a csup
	with date=2009. does not, and the only difference
	is the bce commit. I am using the following lines in rc.conf

	network_interfaces="lo0 bce0 bce1 lagg0"
	ifconfig_lagg0="laggproto lacp laggport bce0 laggport bce1"

	I have not found a way to make this work.
