Re: DPDK supported processor

Thank you for the reply.

I tested l3forwarding sample application, and the results were as below:

Anyway, I'll also try to test the testpmd application.

Hello.

I'm now using Intel Atom processor C2758 on the DPDK testing machines,

but

quoted

it seems not working.

Which sample application would be recommended to test the NIC actually
works well with DPDK?

Best regards

Hi,

Testpmd is the best application you can use for that.

Best regards,
Pablo
