[dpdk-users] EAL: No probed ethernet devices

[dawid_jurek]

Hello Upendra,

"I have bound Intel 82579V nic with
igb_uio and was working on testpmd application and i am not getting any
ports for testpmd probably beacuse of EAL: No probed ethernet devices
error."

Are you sure this device is supported by dpdk? According to NIC's list coming from: http://dpdk.org/doc/nics Intel 82579V is not supported by any PMD. 
To be 100% sure you may look at dpdk source code - dpdk/lib/librte_eal/common/include/rte_pci_dev_ids.h which doesn't contain 82579V as well.  
Good news is that your second card - Intel 82540EM is supported by e1000 from dpdk.

Regards,
Dawid
