Subject: [dts] [PATCH V2 2/2] test_plans/rxtx_offload: add tx offload multi_segs setting plan
Date: Wed, 25 Aug 2021 11:11:48 +0800	[thread overview]
Message-ID: <1629861108-30497-3-git-send-email-yux.jiang@intel.com> (raw)
In-Reply-To: <1629861108-30497-1-git-send-email-yux.jiang@intel.com>

vector path doesn't support multi-segment packet transmit,
only normal path supports multi-segment packet transmit.
Use 'port config 0 tx_offload multi_segs on' or
"--tx-offloads=0x00008000" parameter to enable multi segment offload.

    so this case is just only for i40e.

+Test case: Tx offload multi_segs setting
+======================================================
+
+1. Start testpmd with "--tx-offloads=0x00008000" to enable tx_offload multi_segs ::
+
+    ./testpmd -c 0xf -n 4  -- -i --tx-offloads==0x00008000
+    testpmd> show port 0 tx_offload configuration
+    Tx Offloading Configuration of port 0 :
+      Port : MULTI_SEGS
+      Queue[ 0] : MULTI_SEGS
+
+2. Set fwd to txonly, Set the length of each segment of the TX-ONLY packets, Set the split policy for TX packets, then start to send pkgs::
+
+    testpmd> set fwd txonly
+    testpmd> set txpkts 64,128,512,2000,64,128,512,2000
+    testpmd> set txsplit rand
+    testpmd> start
+
+3. Check TX-packets will not hang and continue to increase::
+    Wait 30s or more, check TX-packets will continue to increase and can be more than 100K

+4. Start testpmd again without "--tx-offloads", check multi-segs is disabled by default::
+
+    ./testpmd -c 0xf -n 4  -- -i
+    testpmd> show port 0 tx_offload configuration
+    No MULTI_SEGS in Tx Offloading Configuration of ports
+
+5. Enable tx_offload multi_segs ::
+    testpmd> port stop all
+    testpmd> port config 0 tx_offload multi_segs on
+    testpmd> port config 1 tx_offload multi_segs on
+    testpmd> port start all

+    Tx Offloading Configuration of port 0 :
+      Port : MULTI_SEGS
+      Queue[ 0] : MULTI_SEGS
+
+6. Set fwd to txonly, Set the length of each segment of the TX-ONLY packets, Set the split policy for TX packets, then start to send pkgs::

+    testpmd> set txpkts 64,128,256,512,64,128,256,512
+    testpmd> set txsplit rand
+    testpmd> start
+
+7. Check TX-packets will not hang and continue to increase::
+    Wait 30s or more, check TX-packets will continue to increase and can be more than 100K
