 Check the Rx checksum flags consistent with expected flags.

+Test Case: Hardware Checksum Check L4 RX
+===========================================
+This test involves testing many different scenarios with a L4 checksum.
+A variety of tunneling protocols, L3 protocols and L4 protocols are combined
+to test as many scenarios as possible. Currently, UDP, TCP and SCTP are used
+as L4 protocols, with IP and IPv6 being used at level 3. The tested tunneling
+protocols are VXLAN and GRE.

+Setup the ``csum`` forwarding mode::
+
+  testpmd> set fwd csum
+  Set csum packet forwarding mode
+
+Start the packet forwarding::

+Test Case: Hardware Checksum Check L3 RX
+===========================================
+This test involves testing L3 checksum hardware offload.
+Due to the relative dominance of IPv4 and IPv6 as L3 protocols, and IPv6's
