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

["lhffjzh" <lhffjzh@126.com>]

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)?
