I wasn't aware until now that there was a public implementation!

Thanks for digging this up.  It's not in any branch that I know of.  I'm
about to go on vacation, but I'll look at it when I get back.  I would
appreciate it if someone would refresh the patch against current ethtool
(preferably reusing some of the functions added for the RX n-tuple
operations).
