Before: if you set ifconfig fxp0 media 100baseTX mediaopt full-duplex, the driver stopped responding to the link probes.. Switches would assume 100-half duplex. If you set the fxp to 'media autoselect', it would correctly get both ends in 100-full. Now, the switch gets it right all the time, even when you have wired the connection and taken it off autoselect. The amount of heartache this has caused here is considerable. I am very very glad it is finally over and fixed... Especially with unmanaged switches that you *cannot* wire the ports. If we plugged in a box that came from a production environment with the speeds wired, there would *always* be a mismatch in the duplex. *THANK YOU*!!! :-) Cheers, -Peter -- Peter Wemm - peter@FreeBSD.org; peter@yahoo-inc.com; peter@netplex.com.au "All of this is for nothing if we don't go to the stars" - JMS/B5 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
