[ale] Slow connection on Cisco Switch

[James P. Kinney III]

Hey Chris. I was out for a while. Looks like you found the magic trick.

Is there a reason that hd should ever be used (assuming all devices are
fd capable)? It seems to me that other than a few, really old modem
protocols and perhaps frame-relay, hd should go the way of the dodo.
Certainly for ethernet traffic.
