Right, so you do not have a static IP address setup for your Ethernet connection (enp2s0)
Also your WIFI overlaps the 192.168.1 range so you would be better off using the 10.10.10.10
address on the 7I80.

The hm2_eth manual page describes setting up a static IP address via the interfaces file

man hm2_eth

The ping results are not complete in above post. I have been trying to do this on 2 computers.
This is the result:

Start over from the beginning, read the Mesa manual, wire the card properly directly to the PC ( it is not connected to the PC you are testing with), set up the WIRED network, not wireless, use different IP range for Mesa.

With Mint you can use the GUI to setup the interface, no need to edit any files.

Thanks, I will do that.

This is result after disabling wireless on the pc that is wired directly to the board.
Am I on the right path?

This looks like you have set your PC ip Address to 10.10.10.10. That is the Mesa ip address. Change the PC to 10.10.10.1 and ping again...
