Actually, I'm sure that all of these boards *do* need MAC WOL and *not* PHY WOL.

The only one I'm unsure about is MT2712, but that's an evaluation board and not
a retail product with "that kind of diffusion".

I think you can just fix the bug in the driver without getting new properties
and such. One commit, two lines.

Cheers,
Angelo
