System: NetBSD 1.5_ALPHA2 NetBSD 1.5_ALPHA2 (JELLYCAT.pnpbios) #6: Fri Sep 15 02:00:50 BST 2000 jasper@jellycat:/usr/src/sys/arch/i386/compile/JELLYCAT.pnpbios i386

	lo0 under netbsd dosn't have the IFF_RUNNING bit set, it probably
	I'm writing some php + snmp web pages for monitering vairous boxes,
and noticed that ucd-snmp maps IFF_RUNNING to ifAdminStatus and IFF_UP to
ifOperStatus, (which imho is the wrong way round). Since netbsd dosn't set
IFF_RUNNING on lo0 ifAdminStatus is set to down which makes it look like lo0
has been ifconfig'd down.

fwiw both Solaris 2.6 and FreeBSD 3.4-RELEASE have IFF_RUNNING on lo0.

	look at the output of 'ifconfig lo0'
(not tested).
