RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

How reproducible:
always

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