Yes and yes

There is already a driver (qca_spi, qcauart) for a similiar Homeplug
device (QCA7000), which also uses IF_PORT_10BASET. Should i change this
too or leave it because of resulting changes to userspace?

AFAIK the device doesn't have any kind of ID register.

@Jimmy Please correct me, if i'm wrong.
