With some buggy switches and other hardware you actually *want* to
bounce the link to get them to properly renegotiate. I can also see
wanting to power off and on a single-PoE-port NIC to restart whatever
device is at the other end, although I don't know if any such devices
exist. Currently the tg3 driver turns the PHY off and on during down/
up on a few of my systems, which I use to make a buggy no-name switch
recognize STP changes properly.

Cheers,
