Subject: Re: [dpdk-dev] Why only rx queue "0" can receive network packet by i40e NIC

Hi Thomas,

Thanks very much for your reminder, you give me many help in this mail list.

The issue with detailed information just as below. but I don't know 
who is the dpdk i40e maintainers? is maintainers@dpdk.org?

Hardware list:
    2 i40e 40G NICs
    Xeon E5-2670 v2(10 cores)
    32G memory

I loopback 2 i40e NICs by QSFP cable, one NIC send UDP network packet by
DPDK,
and another for receiving. I bind 4 processor's logical cores with 4 rx
queue
"0,1,2,3" on receiving NIC, when I start to send packet, only rx queue "0"
can receive
the UDP packet, the others queue always receive nothing. but it is work well
on ixgbe 
10G NICs, I can receive network packet from all rx queues. does anyone
kindly know why?


Regards,
Haifeng

It's possible that you don't have any answer for 2 reasons:
- you replied in a thread dedicated to Cisco enic questions
- you didn't describe your usage enough to understand your problem

I suggest to use the button "new email" instead of "reply all" to
start a new question with enough details.

Did you noticed you put some Cisco guys in CC instead of putting the
Intel responsible for i40e (see MAINTAINERS file)?
