Bingo! That's what I was looking for. I thought there must be
an official way to request that info from the driver.

I just need to add a couple lines of code to our Ethernet
driver to fill in a few more fields in the return struct.  Right
now all it fills in are the p->description and p->snmp_chipset
fields.  I'm not exactly sure why -- it could be that it was
that way in the driver that we used as a starting point, or it
could be due to the fact that on our early platforms link
status info wasn't available.
