[dpdk-dev] Testpmd not recognising device/port even after binding it using the python script

[Aniraj Kesavan]

DPDK version:16.07
OS: Ubuntu 15:04
dual-port Intel X710 10GbE PCI-Express NICs

I have installed the modules, ran the tool to bind them to the NICs,
running gdb over skeleton/basicfwd example shows that rte_eal_init
completes, but it fails at the even number of ports check since
rte_eth_dev_count returns 0. I have tried the examples with and without -w
flags.

Any help is appreciated.

python ./dpdk-devbind.py --status
