--- Comment #16 from Eric Joyner <erj at freebsd.org> ---
We identified a bug in ixl(4) where multicast frames weren't being received in
tcpdump because the driver wasn't setting a multicast promiscuous setting
correctly. The fix (along with other updates) should be going into HEAD for
that shortly, but that doesn't fix the issue with the multicast addresses not
being in the filter list.

Does anyone know if something adds them to the interface's multicast address
list in struct ifnet? If nothing does that, then the driver might have to just
add them to filter list by default...
