Bug 2167658

Description of problem:
i40e card: nic partiion performance case run failed on rhel9.2 ctc2 version

Version-Release number of selected component (if applicable):
[root@dell-per730-52 ~]# uname -r
5.14.0-234.el9.x86_64
[root@dell-per730-52 ~]# rpm -qa|grep openvswitch
openvswitch-selinux-extra-policy-1.0-31.el9fdp.noarch
openvswitch3.0-3.0.0-27.el9fdp.x86_64


How reproducible:


Steps to Reproduce:
DUT i40e card <-connect-> Trex i40e card
1. Create two vfs for pf,
echo 2 > /sys/devices/pci0000:00/0000:00:03.2/0000:07:00.0/sriov_numvfs
set the trust to on
[root@dell-per730-52 ~]# ip link show
 enp7s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether 3c:fd:fe:ad:bc:e8 brd ff:ff:ff:ff:ff:ff
    vf 0     link/ether 00:60:2f:20:0c:36 brd ff:ff:ff:ff:ff:ff, spoof checking on, link-state auto, trust on
    vf 1     link/ether 52:54:00:11:8f:ea brd ff:ff:ff:ff:ff:ff, spoof checking on, link-state auto, trust on

2. Bind vf1 to dpdk and add it ovs bridge, add dpdkvhostuserclient0 to ovs bridge.
 driverctl -v set-override 0000:07:02.1 vfio-pci
 ovs-vsctl set Open_vSwitch . 'other_config={}'
 ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init=true
 ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-socket-mem=1024,1024
 ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=0x50000005000000
 ovs-vsctl --no-wait set Open_vSwitch . other_config:vhost-iommu-support=true
 ovs-vsctl add-br ovsbr0 -- set bridge ovsbr0 datapath_type=netdev
 ovs-vsctl add-port ovsbr0 dpdk0 -- set Interface dpdk0 type=dpdk type=dpdk options:dpdk-devargs=0000:07:02.1
 ovs-vsctl add-port ovsbr0 dpdkvhostuserclient0 -- set Interface dpdkvhostuserclient0 type=dpdkvhostuserclient -- set Interface dpdkvhostuserclient0 options:vhost-server-path=/tmp/dpdkvhostuserclient0

3. Put vf0 directly pass through to master1
4. Start master2 with dpdkvhostuserclient0
[root@dell-per730-52 ~]# virsh list --all
 Id   Name      State
-------------------------
 1    master1   running
 3    master2   running

5. Start testpmd inside master1

6. Start testpmd inside master2
[root@localhost ~]# dpdk-testpmd -l 0,1,2 -n4 --socket-mem 1024 --legacy-mem -- --burst=64 -i --rxd=512 --txd=512 --nb-cores=2 --rxq=1 --txq=1 --disable-rss --forward-mode=macswap --auto-start

7. Used Trex to end traffic, dst mac is master1's mac, it work well. 
python3 /mnt/tests/kernel/networking/fd_nic_partition/no-bond/send.py --pkt_size=64 -c 127.0.0.1 -s 3c:fd:fe:ad:bf:c4 -d 00:60:2F:20:0C:36 --speed=14000000

8. Used Trex to send traffic, dst mac is master2's dpdkvhostuserclient0 mac, 
python3 /mnt/tests/kernel/networking/fd_nic_partition/no-bond/send.py --pkt_size=64 -c 127.0.0.1 -s 3c:fd:fe:ad:bf:c4 -d 52:54:00:11:8f:ea --speed=14000000

Actual results:
Step 6 does not work well, it got 0 performance result.
The testpmd cannot got packet inside master2.

Done.


Expected results:
The testpmd can receive packet and it can got normal performance. 
When changed the host from RHEL-9.2.0-20230115.7 to RHEL-9.2.0-20221122.2, it work well.
