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 o= f (2), you can run l2fwdvf OR l3fwdvf successfully with SR-IOV enabled in E= SXi.
And I do not know wheather ESXi 5.0 = VMM has SR-IOV function or not.

I had trouble getting it to work on a white box ASUS motherboard. It seems the MB didn't support PCIe power management ASPM. And Intel confirmed that was required by Vmware. Linux didn't care if ASPM wasn't available and worked fine with SR-IOV.

SR-IOV needs VT-d enabled and BIOS with _OSC and DMA ACPI tables. The _OSC table is an ACPI control method that the kernel uses to interact with PCIe Active Statep Power Management. Linux just assume no ASPM if table is missing, VMWare ESX 5.1 seems to need it.

Hi Henry,

<= /p>

Thank you very much for y= our help.

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

As far as I known, DPDK(1.2.3) only supports the following NI= Cs:

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

(2) Intel 82599, X540T, X520T chipset based NICs;<= /span>

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

If the NICs on your C220 M3 is one of (2), you can run l2fwdv= f OR l3fwdvf successfully with SR-IOV enabled in ESXi.

And I do not know wheather ESXi 5.0 VMM has SR-IOV function o= r 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 follo= wing 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 Vi= rtual 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.
