Thanks a lot for persevering with this, Alexander.

I've applied this series with minor changes to the last patch.  I
abbreviated the version history in the commit message, and I deleted a
blank line in the manual page additions which made the indentation wrong
for the -U option.  I also recorded the author as you, since you've
largely rewritten it!  The commit message credits Santwona Behera.

You managed to uncover a bug in the sfc driver, which is that
set_rx_ntuple can return a positive value.  Previously ethtool accepted
any non-negative return value as successful, so I made a separate commit
to restore that behaviour.  Of course I'll fix the driver too.

Ben.
