I guess it's improving the situation, but I've got a system with an ethtool that accepts the --json argument, but silently ignores it for -k (ie `ethtool --json -k $DEV` succeeds but doesn't produce a json output), which will still cause the test to fail later.
And --json was added to -k in Jan 2022, that's pretty long ago. I'm not sure we need this aspect of the patch at all..
Ok. Then maybe a silly idea: for the tests that currently have some form of "$TOOL is too old" check, do we want to remove those after a while? If so, how long after the feature was introduced in $TOOL?
Or should we leave them, but not accept new checks to exclude really-old versions of tools? Do we need to document the cut-off ("we don't support tool versions older than 2 years for networking selftests" [or similar]) somewhere in Documentation/ ?
