Issue Description
By using the in-box 1G NIC adapter, I am unable to connect/ping to DRIVE AGX Orin Developer Kit’s 10GbE, ½ H-MTD double, mgbe0_0, port. (I am successfully using the RJ-45/1000BASE-T and RJ-45/10GBASE-T ports without the adapter.)
Looking with ‘ethtool’ or with ‘ip addr’ I can see that mgbe0_0 shows Link Detected even when there are no cables connected to any of the ethernet ports.

• Should the in-box 1GbE NIC adapter work when connected to this 10GbE port, or do I need the 10GbE NIC adapter?
• Why is the link detected even when there is no cable is connected? Is this expected behavior? If not, how to correct the situation? (I assume this should be fixed before trying the 10G NIC adapter as well.)

Dear @sheinisuo ,
Are you using DRIVE AGX Orin devkit or any other platform? Could you share DRIVE OS release details?

[sheinisuo]

Yes, this is with DRIVE AGX Orin devkit.
Right out the box, booted to Ubuntu 20.04.4 LTS, and no additional FW or SW installed on it.
Should this already have a version of DRIVE OS pre-installed? If so, how to check the version?

[SivaRamaKrishnaNV]

Dear @sheinisuo,
You can check version using cat /etc/nvidia/version-ubuntu-rootfs.txt

Could you share connection pictures and ifconfig output?
