When running l3fwd with vPMD, there is one thing to note.
In the configuration, ensure that port_conf.rxmode.hw_ip_checksum=0.
In the configuration, ensure that DEV_RX_OFFLOAD_CHECKSUM in port_conf.rxmode.offloads is NOT set.
Otherwise, by default, RX vPMD is disabled.

As in the case of l3fwd, set configure port_conf.rxmode.hw_ip_checksum=0 to enable vPMD.
As in the case of l3fwd, to enable vPMD, do NOT set DEV_RX_OFFLOAD_CHECKSUM in port_conf.rxmode.offloads.
In addition, for improved performance, use -bsz "(32,32),(64,64),(32,32)" in load_balancer to avoid using the default burst size of 144.
