Does anyone have any experience with multicast Ethernet?  I would like to
use my 386bsd PC as a network node which receives multicast Ethernet packets.
My Ethernet card is NE2000 compatible (ne0), but there is no code in
the driver (i386/isa/if_ne.c) to support multicast.  I presume I need to
set up the card in some way for it to be able to receive these packets.

After doing this, I intend to add a handler to the incoming-packet switch,
so I can decompose my packet into the appropriate data.  That bit I think
I can cope with, but I have no idea about programming the Ethernet board
to actually receive these packets in the first place.

Help??!
