We likely need some mutual coordination here between the patches I've
already posted for PCS support and these patches.

As I've said, we can't deal with multiple ethernet PHYs connected to
one MAC, the patches I've posted cope with that, but likely will need
changes for this.  Conversely, these patches will need changes for my
work.
