EEE 1000BASE-T Resolution

This bit returns the status of the resolution of EEE 1000BASE-T mode. If this bit is set, PHY and remote receiver
have auto-negotiation enabled, and both PHY and link partner advertise EEE 1000BASE-T mode. If this bit is
cleared, either the local or remote PHY does not have auto-negotiation enabled, or local or remote PHY does
not advertise EEE capability in 1000BASE-T mode.

EEE 100BASE-TX Resolution

This bit returns the status of the resolution of EEE 100BASE-TX mode. If this bit is set, PHY and remote receiver
have auto-negotiation enabled, and both PHY and link partner advertise EEE 100BASE-TX mode. If this bit is
cleared, either the local or remote PHY does not have auto-negotiation enabled, or local or remote PHY does
not advertise EEE capability in 100BASE-TX mode.
