Re: DPDK supported processor

It works fine with DPDK at least.

The problem is that OVDK, especially ovs-dpdk command supported by the
OVDK, doesn't work correctly. I tested the DPDK application, l3fwd, in
order to know where the incorrect operation comes from, either DPDK or OVDK
itself. And I know now the issue seems belonging to OVDK. :) In the OVDK,
the physical ports even could not detected...

I have SUPERMICRO A1SRi-2758F mainboard (onboard Atom C2758),
and onboard NICs work fine with DPDK application.

Well, I did think that the NIC in my testing machine may not support DPDK

rather than thinking l3fwd is not working.

I just tested the l3fwd sample application to identify whether the NIC
supports DPDK or not.

Hi

Could you give the details why you think the l3fwd is not working

Hi,

Testpmd is the best application you can use for that.
