Hey Folks,

I see the following message when I attempt to attach pdump to the testpmd sample application:

Pdump output:
EAL: Failed to hotplug add device
EAL: Error - exiting with code: 1
  Cause: vdev creation failed:create_mp_ring_vdev:695

Testpmd output:
Reached maximum number of Ethernet ports
EAL: Driver cannot attach the device (net_pcap_rx_0)
EAL: Failed to hotplug add device on primary

The primary and secondary applications were run using the following commands:

Primary: sudo ./dpdk-testpmd --proc-type=primary --file-prefix=test -d /path/to/pmd
Secondary: sudo ./dpdk-pdump --proc-type=secondary --file-prefix=test -d /path/to/pmd -- --pdump 'port=0,queue=1,rx-dev=./rx.pcap,tx-dev=./tx.pcap'

DPDK version: 22.11.1

Is this a known issue? Is there any known fix for this?

Thanks
Sameer Vaze
