OK, I just saw another thread (phylib: reset mii bus only if reset handler
is registered) which raises a question in my head as to how I should
provide PHY support for a brand-spakin' new driver

Is there any documentation on how I should build a new MAC and PHY driver
from scratch (i.e. what is the official network driver API)
