net/i40e: support MARK and RSS flow action

Browse Source 
Currently, i40e Flow Director action parser only allows following nine
action combinations: (QUEUE, PASSTHRU, DROP, QUEUE + MARK, PASSTHRU +
MARK, DROP + MARK, QUEUE + FLAG, PASSTHRU + FLAG, DROP + FLAG)

Using the existing Cloud Filter profile on the NIC, it is possible to
add support for two more combinations as: (MARK + RSS, MARK + FLAG +
RSS)

Addition of these new combinations would allow more applications to
utilize DPDK rte_flow to implement hardware flow offloads with Intel
Ethernet 700 series network adapters, including but not limited to the
existing OVS DPDK partial hardware flow offload feature.
