ethtool, ixgbe: Move RX n-tuple mask fixup to ethtool
The ethtool utility does not set masks for flow parameters that are not specified, so if both value and mask are 0 then this must be treated as equivalent to a mask with all bits set. Currently that is done in the only driver that implements RX n-tuple filtering, ixgbe. Move it to the ethtool core. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
