So you have the MAC-MAC connection? No back to back PHYs in the
middle. If there is no PHY, linux will not do anything with EEE. What
happens will depend on the reset defaults of the switch. For the FEC
phy_eee_init() will return false, so i expect EEE is disabled.

Handling EEE in the mv88e6xxx driver is something on my todo list. But
i don't expect it to happen soon. And before it will happen we
actually need to decide how the user API should work.
