Networking uses reverse-christmas tree ordering for variables. Please
swap the order of these.
Also, I think this would be better:
unsigned long *supported = phydev->supported;
You don't actually need a separate mask.

For the above four, s/phydev->supported/supported/

Drop this linkmode_or().
You'll then be modifying phydev->supported directly, which is totally
fine.
