The generic analog switch routine is not correct for LP-PHY according
to the latest specs. Implement the proper analog core switch routine.

The spec says:
Else if this in an LP PHY 
     a. If argument "on" is zero 
             1. OR PHY Register 0x43C with 7 
                
             2. OR PHY Register 0x43B with 7

This stuff is executed when on is true (ie. anything else than zero)

You have the if branches swapped. (Don't add a ! in front of the on. Swap the branches).
