[dpdk-dev] [PATCH 2/3] i40e: make sport and dport of sctp flow involved in match

[Jingjing Wu <jingjing.wu@intel.com>]

Due to the NIC's firmware update, the input set of sctp flow is changed
to source IP, destination IP, source port, destination port and
Verification-Tag. This patch adds the sport and dport in the programming
packet of flow director.
