Hi Robert

You should probably post the driver for review. A well written driver
should not even need to care about any of this. phylib and the netdev
driver code does all the work. It only gets interesting when you don't
have a PHY, e.g. a stacked device, like bonding, or a virtual device
like tun/tap.
