Add support for network flow classifier rules

This patch series implements the user-space portion of network flow classifier rules. The original patches were applied to the kernel a couple of years ago, but the user-space side was never applied. As such I have gone though and updated the original patch from Santwona Behera to make it applicable to the current ethtool git tree.

In addition this updates the network flow classification rules to handle displaying the same fields as ntuple filters due to the fact that ntuple display functionality had some serious issues, and provided no means for a driver to display rules if they are stored internally.

The formatting of the man page and the help text may still need some work. I was having difficulties determining the best way to layout the class-rule-add and flow-type help instructions since they are mutually exclusive but both contain a large number of possible options.

Finally there was one minor change adding ESP hashing as a separate option to Rx-hashing that was contained in the original patch that I have moved out into a separate patch.
