Subject: Re: [dpdk-dev] rte_eth_dev_count() returns 0

As far as I known, DPDK(1.2.3) only supports the following NICs:

(1) Intel 82576, 82580, I350 chipset based NICs;

(2) Intel 82599, X540T, X520T chipset based NICs;

(3) virtual NICs generated by SR-IOV from (2).

If the NICs on your C220 M3 is one of (2), you can run l2fwdvf OR l3fwdvf successfully with SR-IOV enabled in ESXi.

And I do not know wheather ESXi 5.0 VMM has SR-IOV function or not.

Further more, please reference to DPDK release notes.

Hi dev-dpdk,

 

I am following a Intel DPDK Step by Step Instruction found here: http://www.slideshare.net/hisaki/intel-dpdk-step-by-step-instructions

My Hello app from the DPDK examples runs fine, but I get the following error when running the l2fwd app:

 

“EAL: Error – exiting with code: 1

Cause: no Ethernet ports – bye”

 

The rte_eth_dev_count() call returns 0, I am using a CentOS 6.3 Virtual Machine on VMWare esxi 5.0 on a Cisco UCS C220 M3 which comes with Xeon E5-2600.  

 

I would really appreciate If you could provide some help to solve this issue.

 

Thank you,

Rui
