It think we will.

The other thing is, drivers/net/phy is becoming a little cluttered -
we have approaching 100 files there.

Should we be thinking about drivers/net/phy/mdio/ (for mdio*),
drivers/net/phy/lib/ for the core phylib code or leaving it where
it is, and, hmm, drivers/net/phy/media/ maybe for the PHY and PCS
drivers?  Or something like that?
