What were you trying to do that didn't work?
Trying to parse the output of the ethtool -l command I notice a difference in missing "headers" in the text output:

It seems this has been fixed in upstream in this commit: https://git.kernel.org/pub/scm/network/ethtool/ethtool.git/commit/?id=b70c928661024cd07914feb49122275daab904ea
What is the impact of this issue to you?
Our test scripts parse this output to ensure proper configuration and deconfiguration, with this change we're unable to run them and would have to implement parsing workarounds for specific versions of ethtool.
