Above support configures 1G to use its PHY normally. 10G can work now
only with the link interrupt mode. Somehow reading of the
string property in fwnode_mdiobus_child_is_phy works only with
DT and cannot cope with 10G PHY nodes as in:

Above root cause will be further checked. In the meantime I will
appreciate any comments or remarks for the kernel patches.

I would like you to figure this out before these changes go in.

Thanks.
