idpf: add flow steering support

Browse source

Use the new virtchnl2 OP codes to communicate with the Control Plane to
add flow steering filters. We add the basic functionality for add/delete
with TCP/UDP IPv4 only. Support for other OP codes and protocols will be
added later.

Standard 'ethtool -N|--config-ntuple' should be used, for example:

    # ethtool -N ens801f0d1 flow-type tcp4 src-ip 10.0.0.1 action 6

to route all IPv4/TCP traffic from IP 10.0.0.1 to queue 6.
