>Description:

	bpf.c isn't prepared to deal with detaching from an interface
	that is down

>How-To-Repeat:

	ifconfig foo up
	tcpdump -i foo &
	<leave it running in the background>
	ifconfig foo down
	<kill the tcpdump, panic>

>Fix:
	
	NetBSD fixed this by checking the return value from ifpromisc
	and not panicing on EINVAL.
