As a nitpick, there is a typo in "thier", which should be "their".

But a real question: where does the number 3 come from? It seems rather
arbitrary, at least without any explanatory comments. The MDIO interface can
support up to 31 devices, so perhaps you should allow for that many PHYs?
(Or perhaps a limit configurable with a #define, as it would seem wasteful
to allocate memory for 31 phy_t structures when I doubt there are any boards
that could truly take advantage of that).

Bye for now,
