Connecting the Xavier Ethernet MAC to a carrier board Host MAC using direct RGMII connection question

Is it possible to connect the Ethernet MAC of Xavier to Ethernet MAC of host FPGA on carrier board using a direct connection via the RGMII pins? I assume I will need to supply clocks and connect RXD–>TXD as well as force connection speed.
Can anyone confirm that they have successfully connected the Xavier MAC this way using a similar set-up?

It works in theory, but not verified on Xavier yet. Hope someone has such experience can share.
