net: fec: add eee mode tx lpi support
The i.MX8MQ ENET version support IEEE802.3az eee mode, add
eee mode tx lpi enable to support ethtool interface.
usage:
1. set sleep and wake timer to 5ms:
ethtool --set-eee eth0 eee on tx-lpi on tx-timer 5000
2. check the eee mode:
~# ethtool --show-eee eth0
EEE Settings for eth0:
EEE status: enabled - active
Tx LPI: 5000 (us)
Supported EEE link modes: 100baseT/Full
1000baseT/Full
Advertised EEE link modes: 100baseT/Full
1000baseT/Full
Link partner advertised EEE link modes: 100baseT/Full
Note: For realtime case and IEEE1588 ptp case, it should disable
EEE mode.
