System: NetBSD turion64.naobsd.org 3.99.7 NetBSD 3.99.7 (TURION64) #2: Tue Aug 16 19:43:57 JST 2005 root@turion64.naobsd.org:/usr/obj/amd64/sys/arch/amd64/compile/TURION64 amd64
Architecture: x86_64
Machine: amd64
>Description:
	emac(4) does not set multicast filter in emac_init(). It causes
	multicast table inconsistency between in-kernel and real device.
	(e.g. rtsol(8) at system startup will fail)
>How-To-Repeat:
	# echo ip6mode=autohost >> /etc/rc.conf
	# echo rtsol=YES rtsol_flags="emac0" >> /etc/rc.conf
>Fix:
	I have no time to test this patch, but it should work.
	(I made (maybe) same patch and tested it. But I lost it...)

	Please pull up to release branch.
