Actually I think the ethtool mention doesn't really apply to the
in-kernel driver. I think I just carried that over from the check-in
for our out of tree driver which hadn't been updated when you added
the code to cleanup the rx ntuple filters.  Also for the driver I'm
not too worried about what the status of it was before since there are
blatant errors in bit/byte ordering and mask bit values in the code
that from what I can tell would have significantly diminished the
usability of the filters.

Thanks,

Alex
