Humm. I don't really like this. These SERDES registers are in a complete different address space to the port, globalX registers. I would suggest adding a new file, 'phy', which allows access to all the phy registers, and SERDES at 0x0f. This also makes it simpler to deal with devices which don't have indirect access to the PHYs via Global 2 offset 0x18 and 0x19. For such chips, the debugfs file should not be created.
