127. vhost PMD Xstats Tests restart test plan

127.1. Description

This test plan will cover the basic vhost pmd xstats test with each path of split ring and packed ring, includes split virtqueue in-order mergeable, in-order non-mergeable, mergeable, non-mergeable, vector_rx path test and packed virtqueue in-order mergeable, in-order non-mergeable, mergeable, non-mergeable path, also cover a stability case. Note IXIA or Scapy packes includes 4 CRC bytes and vhost side will remove the CRC when receive packests.

127.2. Test flow

TG –> NIC –> Vhost –> Virtio–> Vhost –> NIC –> TG

127.3. Test Case 1: xstats test with packed ring mergeable path

  1. Bind one port to vfio-pci, then launch vhost by below command:

    rm -rf vhost-net*
./testpmd -n 4 -l 2-4  --socket-mem 1024,1024 --legacy-mem \
--file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=2,client=0' -- -i --nb-cores=2 --rxq=2 --txq=2
testpmd>set fwd mac
testpmd>start

  2. Launch virtio-user by below command:

    ./testpmd -n 4 -l 5-7 --socket-mem 1024,1024 \
--legacy-mem --no-pci --file-prefix=virtio \
--vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,queues=2,packed_vq=1,mrg_rxbuf=1,in_order=0 \
-- -i --tx-offloads=0x0 --enable-hw-vlan-strip --rss-ip --nb-cores=2 --rxq=2 --txq=2
>set fwd mac
>start

  3. Let TG generate send 10000 packets for each packet sizes(64,128,255, 512, 1024, 1523).

4. On host run “show port xstats 1”, and check the statistic type and number is correct. For example: send 1000 packets with 1028B size(includes 4 CRC bytes), the statistic number of tx_size_1024_to_1522_packets and rx_size_1024_to_1522_packets should both 1000.

  1. Let TG generate send 10000 packets for each different types (broadcast, multicast, ucast).
