I Get a solution and i want share it because someone can need this help.
I am trying run my linuxcnc in archlinux with mesa 7i95 board.

for get my connection with mesa board:

I have installed NetworkManager and net-tools

~ sudo pacman -S networkmanager net-tools

next you can use nmcli for see the devices that you have and the status.

~ nmcli device

In my case it will show my device eno2, type ethernet, state connecting (not connected)
so for connect it i need configure the ip

~ ip address add 10.10.10.10/24 dev eno2

next you can execute a ping for see it work now.

~ ping 10.10.10.10

I hope it help someone!!

Hugs!

Looks like you are pinging the interface on your PC, NOT the Mesa card. Read what Tommy said...
