[dpdk-users] DPDK i40evf problem in receving packet

[dpdk-users] DPDK i40evf problem in receving packet

[Saurabh Mishra]

Hi,

I'm seeing two problems:

1)  when use our kernel '3.10.88-8.0.0.0.6', we only receive first packet
but not subsequent ones at all after that. However, when I use centos7.0,
then l2fwd is able to receive all the packets.

2) I've also seen that on centos7.0, symmetric_mp itself is not working.
dev start fails with 280 error.

i40evf is giving us lot of headache. The i40evf kernel driver works without
any problem. Host is a centos7 KVM. I've already upgraded firmware to
latest.

[Xu, Qian Q]

What's your current firmware info, can u run ethtool -i port_interface to check? 

Thanks

Re: [dpdk-users] [dpdk-dev] DPDK i40evf problem in receving packet

[Saurabh Mishra]

Hi,


*i40e card is :*


00:09.0 *Ether*net controller: Intel Corporation XL710/X710 Virtual
Function (rev 01)

00:0a.0 *Ether*net controller: Intel Corporation XL710/X710 Virtual
Function (rev 01)

firmware-version: f4.40 a1.4 n04.53 e80001dc0

Is there any extra verbose/debug in DPDK which we can enable to find out
why RX does not receive any packet after first one?

Thanks,
/Saurabh
