[dts] [PATCH V1 1/2] Packet capture: upload automation test plan

[yufengmx <yufengx.mo@intel.com>]

Packet capture framework feature support packet capturing on dpdk ethernet devices.
DPDK provides dpdk-pdump tool under app/pdump directory for packet capturing on dpdk.

The  tool is a Data Plane Development Kit (DPDK) tool that runs as
a DPDK secondary process and is capable of enabling packet capture on dpdk ports.
  * The  tool depends on libpcap based PMD which is disabled
    by default in the build configuration files,
    owing to an external dependency on the libpcap development files
    which must be installed on the board.
    Once the libpcap development files are installed, the libpcap based PMD
    can be enabled by setting CONFIG_RTE_LIBRTE_PMD_PCAP=y and recompiling the DPDK.

+  packet capture framework feature
+==================
+
+Packet capture framework feature support packet capturing on dpdk ethernet devices. 
+DPDK provides dpdk-pdump tool under app/pdump directory for packet capturing on dpdk.
+
+The dpdk-pdump application will act as the secondary process. The EAL thread polls for
+packet capture fd. If fd polled matches packet capture fd, it will initiate packet capture 
+processing.
+
+The testpmd application will act as the primary process. The primary process create socket 
+for packet capture connection with the secondary process and registers socket with packet 
+capture epoll event. Packet capture event will be polled as part of interrupt thread.
+
+The primary process creates mempool and two rte_rings for packets duplication and sharing 
+packet info with the secondary process respectively.
+
+Upon receiving packet capture event, the primary process receive either register RX/TX 
+callbacks or remove RX/TX callbacks message from the secondary process on socket.If packet 
+matches, reference count of packet will be incremented and enqueued to second rte_ring for 
+the secondary process to use.
+
+Prerequisites
+=============
+* 2x NICs (2 full duplex ports per NIC) plugged into the available slots on a platform, another 
+two nic ports are linked with cables.
+
+Test cases
+=============
+The testpmd application act as server process with port-topology chained mode, the dpdk-pdump 
+act as client process to dump capture packet with different options setting. Select one port 
+of tester as tx port, another port of tester as rx port, send different type packets from two 
+ports, check pcap files' content dumped by scapy and tcpdump to confirm testpmd working correctly, 
+check pcap files' content dumped by tcpdump and dpdk-pdump to confirm dpdk-pdump working correctly.

+
+port configuration
+--------------------------
+* confirm two NICs physical link on a platform:
+  dut port 0 <---> tester port 0
+  dut port 1 <---> tester port 1
+  
+* Bind two port on DUT::
+ ./tools/dpdk_nic_bind.py --bind=igb_uio <dut port 0 pci address> <dut port 1 pci address>
+
+* On dut, use port 0 as rx/tx port.
+  If dut port 0 rx dump is set, scapy send packet from tester port 0 and tcpdump dumps tester 
+  port 1's packet.
+   
+  If dut port 0 tx dump is set, scapy send packet from tester port 1 and tcpdump dumps tester 
+  port 0's packet.
+
+* If using interfaces as dpdk-pdump vdev, prepare two ports on DUT, which haven't been binded 
+  to dpdk and have been in linked status
