Those are two separate things, probably should be two separate patches.

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.
