If I connect this card up to a 10baseT/UTP hub it will never autoselect. Moreover, if I attempt to force it to media 10baseT/UTP it will never become active, nor will either device see a link. If I force 10baseT/UTP mediaopt full-duplex, then it does get a link and work, but of course every collision becomes an ierr (and a dropped packet) because it's not really a full-duplex connection. >How-To-Repeat: Connect an Intel 21143 chip to a 10baseT/UTP hub. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
