Re: [dpdk-users] testpmd + EAL: No probed ethernet devices + dpdk-17.11.1

["Rosen, Rami" <rami.rosen@intel.com>]

Hi,
You need to bind a device to DPDK before launching testpmd, with the 
usertools/dpdk-devbind.py script. Did you do it? What is the output 
of 
./usertools/dpdk-devbind.py -s
on your host ? do you see any entries under "Network devices using DPDK-compatible driver" when running ./usertools/dpdk-devbind.py -s?

Please take a look in the "Linux Getting Started Guide", section 
4.4: "Binding and Unbinding Network Ports to/from the Kernel Modules"

http://dpdk.org/doc/guides/linux_gsg/linux_drivers.html#binding-and-unbinding-network-ports-to-from-the-kernel-modules

Regards,
Rami Rosen

from the dpdk-setup script, i see there are devices supported by dpdk

Network devices using DPDK-compatible driver ============================================

Other Network devices
=====================
<none>

My understanding is, it should consider the devices under "Network devices using DPDK-compatible driver", but it is not.
The nic that i am using Intel 82599, which is supported by dpdk.

can someone help me to understand what is wrong here?

Thanks,
Venkat
