Hi Michal
I'm not sure of this. I did not build the ethtool my selves, but used the version that comes with Jammy. When testing different versions of ethtool, I used the deb packages found at 
http://archive.ubuntu.com/ubuntu/pool/main/e/ethtool/ and installed with dpkg. 
I assumed however that pretty dump was enabled.

Are you sure your ethtool was built with pretty dumps enabled?
