[V2,1/2] test_plans/vf_offload: add test cases for tunneling packets
Commit Message
DPDK will support outer checksum offload and tunneling TSO in release
22.11, this commit is intended to cover the new scenario of test these
features.
Added new case HW tunneling checksum offload check, covering tunnel
packets for HW checksum offload.
Added new packets to TSO prerequisites and added new case csum fwd
engine, use tunnel TSO, covering tunnel packets for HW TSO.

+Test Case: HW tunneling checksum offload check
+==============================================
+Start testpmd and enable checksum offload on rx port.
+
+Setup the ``csum`` forwarding mode::
+
+ testpmd> set fwd csum
+ Set csum packet forwarding mode
+
+Enable the IPv4/UDP/TCP/SCTP HW checksum offload on port 0::
+
+ testpmd> port stop all
+ testpmd> csum set ip hw 0
+ testpmd> csum set tcp hw 0
+ testpmd> csum set udp hw 0
+ testpmd> csum set sctp hw 0
+ testpmd> csum set outer-ip hw 0
+ testpmd> csum set outer-udp hw 0
+ testpmd> csum parse-tunnel on 0
+ testpmd> port start all
+ testpmd> set promisc 0 on
+ testpmd> start
+ csum packet forwarding - CRC stripping disabled - packets/burst=32
+ nb forwarding cores=1 - nb forwarding ports=10
+ RX queues=1 - RX desc=128 - RX free threshold=64
+ RX threshold registers: pthresh=8 hthresh=8 wthresh=4
+ TX queues=1 - TX desc=512 - TX free threshold=0
+ TX threshold registers: pthresh=32 hthresh=8 wthresh=8

+Send packets with incorrect checksum on outer IPv4, outer UDP (if exists), inner
+IP, inner L4, verify dpdk can rx it and report the checksum error,
+verify that the same number of packet are correctly received on the traffic
+generator side. And IPv4 checksum, TCP checksum, UDP checksum, SCTP checksum need
+be validated as pass by the tester.

+The IPv4 source address will not be changed by testpmd.
