ethtool: Introduce n-tuple filter programming support
This patchset enables the ethtool layer to program n-tuple
filters to an underlying device. The idea is to allow capable
hardware to have static rules applied that can assist steering
flows into appropriate queues.
Hardware that is known to support these types of filters today
are ixgbe and niu.
