IPv6 router solicitation not being received

I have a problem in that the router solicitations are not
	being received by my FreeBSD IPv6 router unless I enable
	promiscuous mode on the tx0 interface.  This causes delays
	to autoconf for other IPv6 boxes on the net until the
	periodic router announcement is sent.

	This leads me to believe that either the multicast hash
	function is wrong or the request for multicast reception
	on the interface is not getting through to the driver.

	"rtadvd tx0" is running so theoretically it should be getting
	through.  Anyone aware of any issues in this area?  Yes the
	kernel is a bit old and needs to be updated.

	Mark

I have had similar problems with tx(4) on FreeBSD 6.0-BETA2, but
unfortunately haven't had time to follow it up yet.

(Just a headsup that this problem may still exist.)

Could you try this patch?  Since I don't have SMC 83c170 card, I
cannot test it by myself.
