Orin PHY AQR113C loopback mode test

Hi nvidia team:

Orin devkit uses marvell aqr113c 10G PHY.
in aqr113c datasheet show supported loopbacks.

How to test PCS loopback mode? set the PHY reg BMCR bit14 1 ?
and how can I test loopback is ok or not?
ifconfig lo down and then ping the ip itself?


Please contact with Marvell for this info.
