Anything running half duplex or 10 Mbps will congest the switch by requiring it to use buffers to store and forward packets. (It can do cut-through switching if there's no speed difference.) We want to save the buffers to relieve congestion if it happens. How about the 3Com Fast Etherlink ISA? The part number is 3C515-TX. --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
