DPDK does not have PMD to support veth. I guess you might want to try to run
DPDK in container, right?
If that is the case, you have to assign a NIC's PF or VF to container to be
driven by DPDK PMD.

Looks like you used a pretty new kernel version with new socket options that
old kernel like my 3.12 does not support. When I tried this patch, it just
cannot build, and compiler complains like below. Which Linux distribution does
this patch work for? How to ensure it works for old kernels?

Tried on 3.12, both of them are undefined. Anyway, will comment them out and
see what performance it could achieve.

KNI is mainly designed for exception path or control plane packets that need to
be pushed
to Linux TCP/IP packets in the kernel. You can push all the packets that DPDK
PMD received
in the user space via KNI to kernel, but majority of them will be dropped for
two reasons: 1) skb

Have you insmod hwmon.ko on your system? Also, you may want to build the DPDK
on your system as KNI kernel module depends on local kernel source code.

The V6 "Interrupt PMD" patch has been sent out to DPDK.org 2 months ago, and V7
is under development with changes
to include more generic APIs that could support all kinds of interrupts (e.g.
HW Rx interrupt and SW ring interrupt).
Stay tuned.

You can do it but it will not sync with DPDK. In current KNI implementation,
the devices'
I/O address spaces are mapped to both userspace DPDK and kenrelspace KNI, so one
can control the NIC device independently(using ethtool for KNI and ethdev APIs
for DPDK)
without synchronization.
In theory,
Thanks for comments and please see my answers inline.

Hello Danny,

It will be always good if you can submit the RFC patch in terms of KNI
optimization.
On the other hand, do you have any perf. data to prove that your patchset could
improve
KNI performance which is the concern that most customers care about? We
introduced
multiple-threaded KNI kernel support la
have plan to
support MP/MC in kernel part of KNI as well?
