Given a system is set up with OVS and DPDK configured on an E830 card on RHEL 9. A VM is set up to forward packets with testpmd in I/O forwarding mode,
When a packet-forwarding test is initiated within the testpmd environment,

Then the testpmd instance should successfully receive and forward packets.
