I just built a 5.3RELEASE machine out of a Gigabyte GA-8I915P Duo Pro,
which has two BCM5751 chips on board.

These interfaces come up at 1000BaseTX according to the link lights on
my switches, but drop back to 100BaseTX/full-duplex when the bge driver
loads.

ifconfig bge0 media 1000baseTX results in no carrier/no link.

link0 doesn't seem to have any effect.

I'm open to suggestions, the point of this was to build a gigabit
Dummynet box.

Some output follows.
