[V2,2/2] test_plans/rxtx_offload: add tx offload multi_segs setting plan
Checks
Commit Message
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.

Note 1: there is no tx_offload per_queue parameter in ixgbe driver,
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
+
+ testpmd> show port stats all

+
+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
+ testpmd> show port 0 tx_offload configuration
+ 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 fwd txonly
+ 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
