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..
