[dpdk-dev] rte_eth_dev_count() returns 0

[Rui Vaz (ruvaz)]

Hi Henry,

Thank you very much for your help.

I have a I350 chipset based NIC, can you tell me why I will not be able to run l2fwd or l3fwd successfully with SR-IOV enabled in ESXi?

Thank you,
Rui

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
