OK for Intel Ethernet chips, you must disable RX IRQ coalescing
This is typically done in the interfaces file

man hm2_eth

for instructions

Also you can try this temporary fix:

sudo ethtool -C eno1 rx-usecs 0

and then try the ping test / LinuxCNC again

(this fix will only last until you reboot)

           hardware-irq-coalesce-rx-usecs 0

to /etc/network/interfaces
