Add a Fixes tag.

The runtime impact of this is just that ethtool will report things
incorrectly, right?  It's not 100% from the commit message.  Could you
please edit the commit message so that an ignoramous like myself can
understand it?

Why is this an RFC instead of just a normal patch which we can apply?
