           Summary: [dpdk-20.11]
                    loopback_virtio_user_server_mode/Basic_test_for_packed
                    _ring_server_mode: loopback throughput is zero
           Product: DPDK
           Version: 20.11
          Hardware: All
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: vhost/virtio
          Assignee: [email protected]
          Reporter: [email protected]

Target Milestone: ---

DPDK version:

    DPDK commit: 46697431adcba206fd5222361bc73c5cf9042a86
    DPDK Comment: test/ring: enhance debug info in failure cases
    DPDK Version: 20.11.0-rc0

OS: Ubuntu20.04.1 LTS (Focal Fossa)/5.4.0-47-generic
Compiler: gcc version 9.3.0
Hardware platform: Intel(R) Xeon(R) Platinum 8280M CPU @ 2.70GHz

Test Setup:
Steps to reproduce:
0, Build DPDK with meson & ninja
CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib -Dc_args='-DRTE_LIBRTE_PMD_PCAP=1' --default-library=static x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc -j 110

Test Case 1: Basic test for packed ring server mode
===================================================
1. Launch virtio-user as server mode::

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-2 -n 4 --no-pci

--file-prefix=virtio \

--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=1,packed_vq=1 -- -i --rxq=1 --txq=1 --no-numa

Quoted 2 lines

set fwd mac
start

2. Launch vhost as client mode::

    ./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 3-4 -n 4 --no-pci
--file-prefix=vhost \
    --vdev 'net_vhost0,iface=/tmp/sock0,client=1,queues=1' -- -i --rxq=1

--txq=1 --nb-cores=1

Quoted 2 lines

set fwd mac
start tx_first 32

3. Run below command to get throughput,verify the loopback throughput is not zero::
testpmd>show port stats all

Show the output from the previous commands:

      dut.10.240.183.214_vhost: show port stats all
      dut.10.240.183.214_vhost:

######################## NIC statistics for port 0 ########################
RX-packets: 0 RX-missed: 0 RX-bytes: 0
RX-errors: 0
RX-nombuf: 0
TX-packets: 0 TX-errors: 0 TX-bytes: 0

Throughput (since last show)

  Rx-pps:            0          Rx-bps:            0
  Tx-pps:            0          Tx-bps:            0

############################################################################

[Expected result]
lookback throughput should not be zero.

net/virtio-user: support vhost status setting

This patch adds support for VHOST_USER_SET_STATUS request. It is used to make the backend aware of Virtio devices status update.

It is useful for the backend to know when the Virtio driver is done with the Virtio device configuration.
