I dont think its connected to thunderbolt. But I am not sure.
So, can you let me know how do I figure this out?
Some additional information if that helps

I can use ethernet even after removing thunderbolt module.
Even when loaded, o/p of
$ lsmod | grep -e thunderbolt -e igc
thunderbolt 397312 0
igc 163840 0
I dont have any other platform with the same Ethernet Controller device.
