I was expecting this patch sooner or later.

Acked-by: Vladimir Oltean <olteanv@gmail.com>

I should take this opportunity and express the fact that it is strange
for MAC drivers to have to sign off all possible copper and fiber
media types in their .phylink_validate method. Sooner or later
somebody is going to want to add 1000Base-T1 too. I don't think it is
going to scale very well. Russell, with your plan to make MAC drivers
just populate a bitmap of phy_modes (MII side), is it also going to
get rid of media side validation?
