On module ethernet controller/PHY property - Energy Efficient Ethernet

We have designed our own carrier board and used Microchip KSZ9031RNX PHY for on module Gigabit ethernet interface realized via RGMII.

I wanted to know if we have Energy Efficient Ethernet is supported or not? AGX Xavier has anything to do with it or it is purely Gigabit Ethernet Transceiver property? In the datasheet I could not find any info on EEE support.

we have 2 Ethernet interfaces one from above RGMII(eth0) and another using I210(eth1). and get below result when checked for EEE
test@hm:~$ ethtool --show-eee eth1
EEE Settings for eth1:
EEE status: enabled - active
But if I run on eth0 I see an error:
test@hm:~$ ethtool --show-eee eth0
Cannot get EEE settings: Operation not supported

Hi, Looks like it is ethernet transceiver. The Energy Efficient Ethernet (EEE) feature is not supported in KSZ9031. However it is available in the KSZ9131 variant.

Yes, that’srelated with ethernet transceiver. Thansk for your confirmation.
