   Yes I agree. A while back I proposed a library of phys. It could be
a driver (stack) just as well. Also, we can make all platforms have
access to some code or config that is PHY related.
   Even thought they are more or less standard, there are some models
that can provide an interrupt or other additional data (like detect
cable disconnect).
