-vhost-user/virtio-pmd vm2vm test plan
+vm2vm vhost-user/virtio-pmd test plan
=====================================
Description
===========
-Test cases for vhost/virtio-pmd(0.95) VM2VM test with 3 rx/tx paths, includes mergeable, normal, vector_rx.
-Also add vhost/virtio-pmd(1.0) vm2vm mergeable test for performance comparsion with vhost/virtio-pmd vm2vm mergeable.
+This test plan includes vm2vm vhost-user/virtio-pmd(0.95) mergeable ,normal and vector_rx path test, and vm2vm vhost/virtio-pmd(1.0) mergeable ,normal and vector_rx path test. Specially, two mergeable path test check the payload of each packets are valid by using pdump.

+3. On VM1, enable pcap lib in dpdk code and recompile::
+
+ diff --git a/config/common_base b/config/common_base

+4. Bind virtio with igb_uio driver,then run testpmd, set rxonly mode for virtio-pmd on VM1::
+
+ ./testpmd -c 0x3 -n 4 --file-prefix=test -- -i --txd=1024 --rxd=1024 --max-pkt-len=9600

+ ./x86_64-native-linuxapp-gcc/app/dpdk-pdump -v --file-prefix=test -- --pdump 'port=0,queue=*,rx-dev=/root/pdump-rx.pcap,mbuf-size=8000'
+
+6. On VM2, bind virtio with igb_uio driver,then run testpmd, config tx_packets to 8k length with chain mode::
+
+ ./testpmd -c 0x3 -n 4 -- -i --txd=1024 --rxd=1024 --max-pkt-len=9600
+ testpmd>set fwd mac
+ testpmd>set txpkts 2000,2000,2000,2000
+
+7. Send ten packets from virtio-pmd on VM2::
+
+ testpmd>set burst 1
+ testpmd>start tx_first 10
+
+8. Check payload is correct in each dumped packets.
+
+9. Relaunch testpmd in VM1::
+
+ ./testpmd -c 0x3 -n 4 --file-prefix=test -- -i --txd=1024 --rxd=1024
+ testpmd>set fwd rxonly
+ testpmd>start
+

+
+ ./x86_64-native-linuxapp-gcc/app/dpdk-pdump -v --file-prefix=test -- --pdump 'port=0,queue=*,rx-dev=/root/pdump-rx-small.pcap'
+
+11. Relaunch testpmd On VM2, send ten 64B packets from virtio-pmd on VM2::
+
+ ./testpmd -c 0x3 -n 4 -- -i --txd=1024 --rxd=1024 --max-pkt-len=9600
+ testpmd>set fwd mac
+ testpmd>set burst 1
+ testpmd>start tx_first 10
+
+12. Check payload is correct in each dumped packets.
+
+Test Case 7: vm2vm virtio1.1 mergeable path test with payload check
+===================================================================
+
+1. Launch testpmd by below command::
+
+ rm -rf vhost-net*
+ ./testpmd -l 1-3 -n 4 --socket-mem 1024,1024 --no-pci \
+ --vdev 'eth_vhost0,iface=vhost-net,queues=1' --vdev 'eth_vhost1,iface=vhost-net1,queues=1' -- \
+ -i --nb-cores=2 --txd=1024 --rxd=1024
+ testpmd>set fwd mac
+
+2. Launch virtio-user by below command::
+
+ ./testpmd -n 4 -l 7-8 --socket-mem 1024,1024 \
+ --no-pci --file-prefix=virtio1 \
+ --vdev=net_virtio_user1,mac=00:01:02:03:04:05,path=./vhost-net1,queues=1,packed_vq=1,mrg_rxbuf=1,in_order=0 \
+ -- -i --nb-cores=1 --txd=1024 --rxd=1024 --max-pkt-len=9600
+ testpmd>set fwd rxonly
+ testpmd>start
+
+3. Attach pdump secondary process to primary process by same file-prefix::
+
+ ./dpdk-pdump -v --file-prefix=virtio1 -- --pdump 'device_id=net_virtio_user1,queue=*,rx-dev=/root/pdump-rx.pcap,mbuf-size=8000'
+
+4. Launch virtio-user by below command::
+
+ ./x86_64-native-linuxapp-gcc/app/testpmd -n 4 -l 5-6 --socket-mem 1024,1024 \
+ --no-pci --file-prefix=virtio \
+ --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,queues=1,packed_vq=1,mrg_rxbuf=1,in_order=0 \
+ -- -i --nb-cores=1 --txd=1024 --rxd=1024 --max-pkt-len=9600
+ testpmd>set fwd txonly
+
+5. Send large packets from net_virtio_user0::
+
+ testpmd>set txpkts 2000,2000,2000,2000
+ testpmd>set burst 1
+ testpmd>start tx_first 10
+
+6. Check payload is correct in each dumped packets.
