So you have XGMII between the MAC and the PHY. That should support
2.5G, 5G and 10G. What i don't know is if you can also do 10/100/1000
over XGMII?
How are you currently connecting your 1G PHY to the MAC? XGMII is a
big parallel bus, where as SGMII is a small serial bus.
I would say, before this patchset goes anywhere, you need to test
10/100/1000/2.5G/10G, with at least one PHY.
Alternatively, take out support for 2.5G/10G and C45, and post patches
for just > 1G and C22. That you can test and you know works. You can
add the rest later.
