How reproducible:
always

Steps to Reproduce:
Server and Client is connected back to back
Server side :
1. bind 2 ice ports to vfio-pci

1. driverctl list-overrides
   0000:6c:00.2 vfio-pci
   0000:6c:00.3 vfio-pci
   2.start testpmd with command :
   dpdk-testpmd --lcores 2-10 -a 0000:6c:00.2 -a 0000:6c:00.3 – -i --auto-start
   3.use the following commands in testpmd
   testpmd>stop
   testpmd>port stop all
   testpmd>set verbose 9
   testpmd>rx_vxlan_port add 4789 0
   testpmd>rx_vxlan_port add 4789 1
   testpmd>port start all
   testpmd>start

Client Side:
start scapy, sent packets
send_pkt_num = 10
size = 64
pkt = Ether()/IPv6(src="3000::100",dst="3000::200")/UDP()/VXLAN()
pkt.dst = 'Client_nic2_mac'
payload = 10 * 'x'
pkt.add_payload(payload.encode())
pkt.show()
sendp(pkt,count=send_pkt_num,inter=1,iface='Client_nic1_name')

Actual results:
There is no packet captured in testpmd

Expected results:
There should be 10 packets in testpmd, And the Client nic2 should receive 10 packets

Additional info:
send ipv4 traffic ,match the expected results.
