I think people use it - why do you think it isn't supportable?
Why would it need to be any different from something like SGMII? One
can implement a "phylink_pcs" that responds appropriately when in RGMII
mode (which I believe is what others have done.)
Note that Marvell net drivers always register a PCS no matter what
interface mode is being used - I believe the hardware has the ability
to read the RGMII in-band and in that case it's just the same
registers that one has to read to get the status as SGMII.
