Basically, it's a rip-it-all-down-and-start-over way of restarting the
connection, and is also useful for fixing queues that are misbehaving.
It's a little old-fashioned, taken from the ixgbe example, but is
effective when there isn't an actual "restart auto-negotiation" command
in the firmware.
I'll try to make it a little more evident.
