Subject: [dts] [PATCH V1 2/2] test_plans/multiprocess: add 2 cases
Date: Tue, 27 Dec 2022 15:20:51 +0000	[thread overview]
Message-ID: <20221227152051.504672-2-songx.jiale@intel.com> (raw)
In-Reply-To: <20221227152051.504672-1-songx.jiale@intel.com>

in DPDK multiprocess, all operations done by the secondary process on the hardware are invalid.
so action 'port stop' and 'port reset' only work in primary process. 
add 2 cases to test it.

+TestCase : test_multiprocess_port_stop
+======================================
+Subcase 1: secondary_port_stop
+------------------------------
+test steps
+~~~~~~~~~~
+
+1. Launch the app ``testpmd``, start primary process and secondary process with the following arguments::
+
+   ./dpdk-testpmd -l 1,2 --proc-type=auto -a 0000:17:00.0  --log-level=ice,7 -- -i --rxq=8 --txq=8  --num-procs=2 --proc-id=0

+
+2. stop fwd in secondary process and start fwd in primary process::
+
+    secondary process:
+      testpmd> port stop 0
+
+    primary process:
+      testpmd> set fwd rxonly
+      testpmd> set verbose 1
+      testpmd> start
+
+3. send 1 packet from scapy::
