		expanding needs of 10-Gigabit Ethernet devices, Clause 45 of the
		802.3ae specification provided the following additions to MDIO:

		- Ability to access 65,536 registers in 32 different devices on
		  32 different ports
		- Additional OP-code and ST-code for Indirect Address register
		  access for 10 Gigabit Ethernet
		- End-to-end fault signaling
		- Multiple loopback points
		- Low voltage electrical specification
