I was expecting this patch sooner or later.

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?

You're touching on a concern I've had for some time that the link modes
mix together several different parameters: speed, duplex, and media.
What we actually want for a MAC is to know which speeds and duplexes
they support for each interface mode, and then translate that to the
ethtool link modes as appropriate. That isn't a problem I've addressed
yet, but something that could be addressed.
I've just updated my net-queue with a bunch of stuff that's been
sitting in other branches (some published, some not), which includes
the PHY_INTERFACE_MODE bitmap changes - everything from and including
"net: mvpp2: add port support helpers" concerns the bitmap stuff.
At the moment, it has to support both the new bitmap solution and the
legacy solution, but hopefully in time we can drop the legacy solution.

Applied to net-next, thank you.
