Do you have any idea why the new one is AN, and previous one is EN?  I
just like consistent naming, or an explanation why it is not
consistent.

EN EcoNet that was then absorbed by Airoha (AN). Hence it's the same
thing. Airoha is suggesting to use AN for new submission. So it's just
about timing.

Is there any documentation about the ID, and the lower nibble. Given
it is 0, i'm wondering if PHY_ID_MATCH_EXACT() is correct.

I will check this but I doubt there is any explaination. These are internal
to the switch so my theory is that no exact logic was applied.
