As I've already said, this conflicts with work that I have in progress,
which will remove the serdes support from this driver _if_ we can get
forward progress on the PCS bits from Mohd - that has become dependent
on sorting out the MDIO bus clock which seems to have been totally
broken in this driver for quite some time so that we can have confidence
that any testing that is done is actually being done on a setup which is
running within correct specification (and not running the MDIO bus at
some insane speed that may lead to data corruption.)

FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
