Subject: [PATCH] Add ipsec policy test suites with flow director or rss
 accelerated

The test scenario is about two private networks which communication was
protected by ipsec.

The test suites are to show performance impovement about ipsec esp flow
lookup that offloaded by NIC flow director and rss.

Verified on 3n-clx and Intel E810 NIC environment, with 64B ipsec packet
flow, performance improved ~31% with 1C2T, ~110% with 2C4T, ~250% with 4C8T.

+| Documentation | **IPv4 IPsec tunnel mode performance test suite.**
+| ... |
+| ... | - **[Top] Network Topologies:** TG-DUT1-DUT2-TG 3-node circular \
+| ... | topology with single links between nodes.
+| ... |
+| ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 on TG-DUTn, \
+| ... | Eth-IPv4-IPSec on DUT1-DUT2.
+| ... |
+| ... | - **[Cfg] DUT configuration:** DUT1 and DUT2 are configured with \
+| ... | multiple IPsec tunnels which shared same tunnel src and dst ip \
+| ... | address, enabled flow rss action between them.\
+| ... | DUTs get IPv4 traffic from TG, encrypt it and send to another DUT, \
+| ... | where packets are decrypted and sent back to TG.
+| ... |
+| ... | - **[Ver] TG verification:** TG finds and reports throughput NDR (Non \
+| ... | Drop Rate) with zero packet loss tolerance and throughput PDR \
+| ... | (Partial Drop Rate) with non-zero packet loss tolerance (LT) \
+| ... | expressed in percentage of packets transmitted. NDR and PDR are \
+| ... | discovered for different Ethernet L2 frame sizes using MLRsearch \
+| ... | library.
+| ... | Test packets are generated by TG on \
+| ... | links to DUTs. TG traffic profile contains two L3 flow-groups \
+| ... | (flow-group per direction, number of flows per flow-group equals to \
+| ... | number of IPSec tunnels) with all packets \
+| ... | containing Ethernet header, IPv4 header with IP protocol=61 and \
+| ... | static payload. MAC addresses are matching MAC addresses of the TG \
+| ... | node interfaces. Incrementing of IP.dst (IPv4 destination address) \
+| ... | is applied to both streams.
+| ... |
+| ... | - **[Ref] Applicable standard specifications:** RFC4303 and RFC2544.
