- *			The PHY cannot wake up on its own.
- *
- *		- energy detect mode
- *			Power consumption: ~160 mW
- *			The PHY can wake up on its own by detecting activity
- *			on the CAT 5 cable.
- *
- *		- energy detect plus mode
- *			Power consumption: ~150 mW
- *			The PHY can wake up on its own by detecting activity
