As far as I know, there is nothing wrong. Your kernel must have
been compiled with multicast support, and it is trying to "subscribe"
to the general multicast group.
I believe the multicast RFC(s) mandates this. Win9x clients do this
also.
To get rid of these packets, just compile your kernel without
the multicast option.
Hope it helps.
