What kind of bge? Are these the same onboard 5703 on IBM servers for
which Matt Thomas(?)  added support, or something else again?

IIRC, that message (and calling bge_tick for link events) is allegedly
a workaround for a hardware bug/misfeature on the bcm5700 chip: the
hardware link-state FSM is broken and has to be checked in software.
The driver should not be taking that path at all for a 5701 or newer.

That's what you would get if the driver is not applying the correct
PHY/DSP patch for your particular hardware revision. What rev does the
driver claim, and what are the acutal PCI register values?

FWIW,I had no problems (once the DSP patches were correct) with
bcm5700s or 5704s, to Cisco Catalyst or Extreme Summit switches.

It would help to know *exactly* what family and chip is affected
(e.g., bcm 5703, revision a2). If the driver doesn't give that much
detail, we can figure it out from the PCI registers.
