Hi Andrew,

Isn't the serdes interface just a normal PHY - the register set in
Viviens debugfs patch certainly looks like an 88e1545 in one of the
switches I've here (I think on the dev rev B).  Is there a reason why
this PHY isn't visible as a normal PHY, just like we export the other
internal PHYs?
