Hi Andrew,

Thanks for the hint, I will test this, but while reviewing the datasheet,
the port 5 has no PHY, so must only be used as cpu port.

I also have another patchset which fixes 2 setup registers writes and
adds a shiny new mv88e6060.h based on mv88e6xxx.h.
I think the removal of the poll_link in mv88e6060 should be in this patchset.

Neil
