Most 3com cards don't have a programmable multicast filter, so to handle multicast you have to put them into promiscuous mode and then do the filtering manually (ie. more software overhead). The new 3c905B does have a real multicast filter, and some of their older hardware (eg. 3c503, 3c505) might have done OK, but the '509 and '589 certainly don't. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
