I guess I've clobbered extended address register. How about
attached one?

There could be other issues in msk(4) for dual port controllers but
let's focus on PHY issue first.

I guess you may have to specify "mediaopt full-duplex" in the

There are a copule of code path that applys to dual port
controllers. For example MSI is not supported even though hardware
actually support that feature. That would be next item to try.
