this becomes mandatory now, PMD have no choice. There is no "rte_dev_probe_local".

the requirement for PCAP PMD from pdump is, it need to support data path on secondary process, so the patch enable it.
Btw, I just got validation result, seems the patch only works on PCAP file dump, it still have issue to dump packet to a netdev interface.
So I want to hold this patch, I will submit a v2 to fix that issue.
