Hello,

I'm using dpdk-22.03 in an Ubuntu 20.04 Virtual Machine using VirtualBox.

Two network devices are binded.
./usertools/dpdk-devbind.py --status

Nework devices using DPDK-compatible driver
0000:00:08.0 "8254EM Gigabit........" drv=uio_pci_generic unused=e1000,vfio-pci
0000:00:09.0 "8254EM Gigabit........" drv=uio_pci_generic unused=e1000,vfio-pci

I am testing the pipeline application and the given examples (registers.cli, l2fwd.cli...),
but the pipeline port in / port out commands always fail.

For example, testing
dpdk-pipeline -l0-1 -- -s ./examples/pipeline/examples/registers.cli

mempool MEMPOOL0 buffer 2304 pool 32K cache 256 cpu 0 -> OK

link LINK0 dev 0000:00:08.0 rxq 1 128 MEMPOOL0 txq 1 512 promiscouos on -> OK
link LINK1 dev 0000:00:09.0 rxq 1 128 MEMPOOL0 txq 1 512 promiscouos on -> OK (also checked using "link show")

pipeline PIPELINE0 create 0 -> OK

pipeline PIPELINE0 port in 0 link LINK0 rxq 0 bsz 32 --> port in error
pipeline PIPELINE0 port in 1 link LINK1 rxq 0 bsz 32 --> port in error

pipeline PIPELINE0 port out 0 link LINK0 txq 0 bsz 32 --> port out error
pipeline PIPELINE0 port out 1 link LINK1 txq 0 bsz 32 --> port out error
 
rte_swx_ctl_pipeline_port_in_config(p->p, port_id,"ethdev",&params) returns -22 (EINVAL) incorrect values

The same happens testing l2fwd_mac_swap_pcap.cli which uses "source" and "sink" types.

Thanks in advance
