[dpdk-dev] How to use dpdk ring and mem lib in kernel level?

[GongJinrong]

Hi, guys

   Can dpdk support allocate mempool and create ring in kernel level? I know
dpdk is user space driver, but many application need a channel to transmit
data from kernel to user space without any hardware dependency(just like pf
ring)? Anyone has a sample like this?

Best Regards

[dpdk-dev] Signature filter for virtual function

[Ilan Borenshtein]

Hi,

Is there any other way except of the Flow director to use the different Rx 
queues by a VF ?
Will the next versions support flow director for VF ?

Thanks,
Ilan B

Hi

Flow director is not supported on VF now.
I think this may be the reason why ENOTSUP is returned.
