I don't have a strong preference, although where I come from, all new
NXP networking drivers are still labeled as "freescale" even though
there is no code reuse. There are even less commonalities with
Microchip (ex-Micrel, if I am not mistaken) KSZ switches than with the
old vsc73xx. I'll let the ex-Vitesse people decide.
