Re: [Etherboot-developers] About multicast

It's not as visible :-)
Usually it is just one byte or so sent to the network device telling it that
it should not only accept unicast packets to its own address and broadcast,
but also multicast packets. There are not many drivers up to now AFAIK, but
it's no great job to implement this single output. The rest is handled inside
etherboot which examines all incoming (and accepted) packets and sees they
are multicast if their address is something like 225.0.0.1 or so.
Really, for the nic specific stuff, there's not much to see.

If you don't get it yourself for your board, tell me which model (etherboot
driver, linux driver will probably do) you have and I can have a look at it.
