Add basic flow steering. For now, we support IPv4 and TCP/UDP only.
Patch 1 renames "enum virtchnl2_cap_rss" to a more generic "enum
virtchnl2_flow_types" that can be used with RSS and flow steering.
Patch 2 adds the required flow steering virtchnl2 OP codes and patch 3
adds the required flow steering ethtool ntuple ops to the idpf driver.
