[dpdk-dev] Debugging EAL PCI / Driver Init

I am running into a problem where Eth driver init works fine in a sample app
and finds my NICs, and the NICs appear in rte_eal_pci_dump(stdout) but they
don't show up in rte_eth_dev_count() even after rte_eal_pci_probe() is called
the same as the sample apps, so my app won't boot.
I have a lot of experience using the older versions of the DPDK where you had
to call the PMD init functions manually but no experience with the later
versions where the DPDK is supposed to init the PMDs itself automatically.
What do I have to do to dump the most possible debug output on why the driver
list for my PCI devices always seems empty? Any places I should look to see
the issue? Maybe I didn't link it together with the right DPDK libs? I used
the combined DPDK static lib libintel_dpdk.a to make things simpler as I had
seen recommended in various places.
