[dpdk-dev] 82599ES NIC support

> Can you check if your PCI device ID is listed in "lib/librte_eal/common/
include/rte_pci_dev_ids.h"?

82599ES is not listed in lib/librte_eal/common/
include/rte_pci_dev_ids.h

On the other hand, 82599EB (which works okay with DPDK) is not listed there
either.

using "tools/pci_unbind.py" (maybe renamed to tools/igb_uio_bind.py)?

Yes:

$ sudo pci_unbind.py --status

Network devices using IGB_UIO driver
====================================
0000:07:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection' drv=igb_uio

I enabled debugging as you said, and run testpmd app.

It ends with an error "Cause: No probed ethernet devices - check that
CONFIG_RTE_LIBRTE_IGB_PMD=y and that CONFIG_RTE_LIBRTE_EM_PMD=y and that
CONFIG_RTE_LIBRTE_IXGBE_PMD=y in your configuration file"

Here is the detailed debug output:
