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
