This is one of many modified versions of the driver.
Not generating link beat isn't a usual problem, but we only test
Scyld-released drivers here.

You can try the updated driver at

You need to run
    pci-config -#6

The important detail is if the interface is a powered-down state (D1 D2 or
D3 instead of D0).
