System: NetBSD argo.mewburn.net 1.6T NetBSD 1.6T (ARGO from GENERIC-$Revision: 1.558 $) #0: Wed May 14 19:27:36 EST 2003 lukem@argo.mewburn.net:/var/obj/i386/usr/src/sys/arch/i386/compile/ARGO i386

>Description:
	"ifconfig -l -b" is documented as:
		 -b (only list broadcast interfaces)

	However, this is implemented by skipping interfaces with the
	POINTTOPOINT or LOOPBACK flags set, not by only including
	interfaces with the BROADCAST flag set.  This means we get
	interfaces such as "stripN" in the "-b" output.

>How-To-Repeat:
	Run "ifconfig -lb" on a GENERIC system and notice that strip0
	appears.

>Fix:
	Change the tests in ifconfig(8) from
		(ifa_flags & IFF_POINTTOPOINT|IFF_LOOPBACK)
	to
		! (ifa_flags & IFF_BROADCAST)
	?
