" IRQ coalescing is not disabled." How can I do that?

man hm2_eth

for instructions for doing this permanently

to test temporarily:

sudo ethtool -C eno1 rx-usecs 0
 

Hi PCW,
the result with the ethtool is very sufficient:
 

So, do I have to copy this line in my .hal file? Or is there another way to do that permanently? I don't find that clearly in the manual doc. I'm sorry that I'm not a Linux pro but a newbie to all that.
Thanks, Arno

As described in the hm2_eth man page, it involves adding the appropriate text
to the /etc/network/interfaces file, in your case, adding something like:

       auto eno1
       iface eno1 inet static
           address 10.10.10.2
           hardware-irq-coalesce-rx-usecs 0


You need to run the editor as root (with sudo) to edit this file

After editing the file its probably best to re-boot and then check if the
setting works with:

ethtool -c en01



 

Hello PCW,
thank you for your answers! (sorry for delay, I was very busy the last days and couldn't do anything at my machine.)

I tried the lines in /etc/network/interfaces file and  after reboot my internal Intel network was disabled. Just  auto internet with RLT8111 is possible. The file is as follows:
 

Well, internet network is ok. What is the faulty setting here?
 

This is the feedback of ip a without the suggested lines:

And this is ip a with the 4 lines in /etc/network/

valid_lft forever preferred_lft forever

why does it change the altname to enp0s25? that is a conflict with 2. where can I change the altname manually to fix this?
Or should I change the priorities so that eno1 is launched before enp2?

Hmm I tried both, changed priorities eno1 to 1 and auto/enp2 to 0 - no effect.
Then I changed the position of the lines in /etc/network/interfaces - no effect at all.

On what reason ever, the network definitions are faulty.

WTF is going on there?

The only thing that I see is  different is the netmask

you might try

address 10.10.10.2/24

Also ipv6 has been enabled, which is really odd
