i40e: Add Energy Efficient Ethernet ability for X710 Base-T/KR/KX cards
Add "EEE: Enabled/Disabled" to dmesg for supported X710 Base-T/KR/KX
cards. According to the IEEE standard report the EEE ability and the
EEE Link Partner ability. Use the kernel's 'ethtool_keee' structure
and report EEE link modes.
Example:
dmesg | grep 'NIC Link is'
ethtool --show-eee <device>
Before:
NIC Link is Up, 10 Gbps Full Duplex, Flow Control: None
Supported EEE link modes: Not reported
Advertised EEE link modes: Not reported
Link partner advertised EEE link modes: Not reported
After:
NIC Link is Up, 10 Gbps Full Duplex, Flow Control: None, EEE: Enabled
Supported EEE link modes: 100baseT/Full
1000baseT/Full
10000baseT/Full
Advertised EEE link modes: 100baseT/Full
1000baseT/Full
10000baseT/Full
Link partner advertised EEE link modes: 100baseT/Full
1000baseT/Full
10000baseT/Full
