I need an answer

Also note:

Intel MACS need to have IRQ coalescing disabled

This is described in the hm2_eth man page

Thanks for your reply, understand I am a newbie with Linuxcnc. After searching the web (and search here) to seem if I could understand the IRQ coalescing disable.
You had suggested using the command sudo ethtool -C enp0s25 rx-usecs 0 to see if that cleared up the problem. I understand that is not a real fix, just a test. I will do that, also other info talks about disabling
vitualization in the BIOS of the PC may help as a fix
If I am incorrect please elaborate

Yes,

sudo ethtool -C enp0s25 rx-usecs 0

will only change the IRQ setting until the next reboot

But it should improve network latency, which you can test by pinging the FPGA card
before and after the ethtool command

To make the fix permanent, you add the command to the interfaces file as described
in the hm2_eth manual page

There seems to be no change in the ping times, left after boot and right after command installed.
 

 

Those ping times suggest that you are not pinging the FPGA card but the host itself
(that is you have the host IP address set to 10.10.10.10 rather than say 10.10.10.100)

 Ok how and where do I change it  I am a fish out of water
 

In the IPV4 tab, set the IP address to 10.10.10.X
Where  X is not 0, 1, 10, or 255

Also disable IPV6 addressing

 

Do I need to remove and enter it as a new connection???

No, you edit the existing connection

it dose not change the numbers in the box. I have change them in IPv4 and click apply and nothing happens  thanks for hanging with me on this 
I understand how hard it is to remote troubleshoot, I have done it many times, just not with Linuxcnc
