Hi Florinel

This is still a PHY device. I don't remember any discussions which
resolved the issues of if at the end of the backplane there is another
PHY.

It makes little sense to repost this code until we have this problem
discussed and a way forward decided on. It fits into the discussion
Russell and Ioana are having about representing PCS drivers. Please
contribute to that.
