I don't think it makes sense to add credits for features in ethtool.c
when they're entirely implemented in other source files. I know there
are a lot of these already but I'd guess these date from before those
separate files existed. Put your name and copyright in smsc9420.c, and
in AUTHORS if you like.

Why aren't the PHY register values horizontally aligned while the MAC
and DMA registers are?
