I agree ethtool is not very well documented. However, i would follow
what -s does. You can pass link modes you want to advertise, and you
can turn auto-neg on and off. Does turning auto-neg off and on again
reset the links modes which are advertised? I don't actually know, but
i think the behaviour should be consistent for link modes and EEE
modes.
