Re coalescing.

will tell you if its supported on your card and list the coalescing parameters if supported.
If not, it will say.
 Operation not supported

 
Is ethtool -c eth0 used with some other command?

Probably needs sudo. Sorry.

My thoughts after  last night's failure where reltek cards are in use is to use the 5.17 kernel (or 5.19 if only supporting the R8125)
This should allow you to download and build the Realtek drivers if it is an issue

Broadcom chips on mac same issues

got smart serial port dolt not cleared from previous, any ideas

Same issue, excessive Ethernet latency.

I decided to look for a non-debian distro and spurred on by Joco's post  below settled on  Arch Linux
forum.linuxcnc.org/9-installing-linuxcnc...nc-2-9-on-arch-linux

There is an installer but I could not get  it to write to the HDD. So I followed this video to install it the long way round
  
Its very comprehensive and includes sections on UEFI and encrypted HDD's which you don't need to watch. Its quite a low level tutorial on Linux,

I've now got an XFCE desktop with Preempt_RT installed. The wifi and network just came up. So I just have to work out how to set a fixed ip address and get on with building linuxcnc which is the easy bit.

I figuured it would be nice to get away from all the Debian issues we've experienced. They say Arch uses plain Linux so hopefully, they leave out the yucky stuff Debian has included. Time will tell.

Well, its taken a while but I now have a RIP instance on ArchLinux with xfce installed and running qtplasmac connected to a 7i76e
I had one hiccup with incorrect permissions on BWidget which prevented linuxcnc from opening. I documented the soluution in the Arch thread here in the forum I shared earlier.
The ping times are significantly faster (around 1 ms)
Initially, I got some errors about smart serial being too slow but after adding isolcpus=2,3 using grub-optimizer, that seems to have gone away.
So I've had quite enough of Linux for one day!

I'll leave this for a few hours but I think the error finishing read is fixed! What a nightmare to get here on this particular PC.
