Dear All,

I put multicast-capability on 3com509 by making very small
modification on i386/isa/if_ep.c. I checked the function by receiving
NASA shuttle Mission with vic-2.6. Also mrouted3.4 works on the card
correctly.

There are two modifications:

1. Add IFF_MULTICAST flag in epattach(),
2. Add SIOCADDMULTI and SIOCDELMULTI handling in epioctl().

I included the context-diff file at the end of this mail. 

Best regards,

Masayuki Yanagiya
