What were you trying to do that didn't work?

Please provide the package NVR for which bug is seen:

4.18.0-513.5.1.el8_9.x86_64

dpdk-21.11-3.el8.x86_64

How reproducible:

always

Steps to reproduce

there are back-to-back topology. Client runs scapy, Server runs dpdk-testpmd

for server

1. create 1 vf on pf, then set spoofchk on and trust on for vf
2. run dpdk-testpmd
3. dpdk-testpmd a 0000:04:00.2   -i --forward-mode=macswap --auto-start
4.  run command inside testpmd>         stop
              > set verbose 9
               >port stop all
               >set promisc all off
               >port start all
               >start
5. after client send traffic,  there are 2 packets captured in testpmd

for client

1. send no tag /tag/qinq traffic separated

python -c 'from scapy.all import *; sendp(Ether(src="0c:42:a1:22:a3:46", dst="f6:2e:92:c3:f1:ae")//IP(src="1.1.1.1", dst="2.2.2.2")/ICMP(), iface="enp4s0f0", inter=1)'   ##dstmac is server vf mac

python -c 'from scapy.all import *; sendp(Ether(src="0c:42:a1:22:a3:46", dst="f6:2e:92:c3:f1:ae")/Dot1Q(vlan=10)/Dot1Q(vlan=20)/IP(src="1.1.1.1", dst="2.2.2.2")/ICMP(), iface="enp4s0f0", inter=1)'   ##dstmac is server vf mac

 python -c 'from scapy.all import *; sendp(Ether(src="0c:42:a1:22:a3:46", dst="f6:2e:92:c3:f1:ae")/Dot1Q(vlan=10)/IP(src="1.1.1.1", dst="2.2.2.2")/ICMP(), iface="enp4s0f0", inter=1)'   ##dstmac is server vf mac

       2. capture packets on enp4s0f0 ,

Expected results

capture 2 packets on client side

Actual results

there is just 1 packet once
