[dpdk-dev] pci_unbind.py failure

[Vladimir Medvedkin]

Hi all,

I have faced with similar problem on my real environment with 82599 nic.
Looks like in some cases rte_eth_dev_count() return 0 instead of real
number of igb_uio binded ports. After restarting app several times
rte_eth_dev_count() return real number of ports and continue execute
normaly.
