no joy with 3.3-rel, 3.3-stable or 3.3-current on my PE1650. (2 x em)

if i use some random white-box pc with 2 fxp's it works great. if i
switch my external (ospf-running) interface from my trusty fxp to an
em card, multicast (and ospf) does not work. putting the gig card in
promiscuous mode makes everything happy again, but that's inelegant.

     GDB has a 'break' feature; why doesn't it have 'fix' too?
