Hi,

08/01/2018 15:37, Remy Horton:
> Port Representors provide a logical presentation in DPDK of VF (virtual

Extending control plane ability of DPDK has been discussed
multiple times.
The current agreed policy is:
"
The primary goal of DPDK is to provide a userspace dataplane.
Managing VFs from a PF driver is a control plane feature and developers
should generally rely on the Linux Kernel for that.
"
http://dpdk.org/doc/guides/contributing/design.html#pf-and-vf-considerations

If we relax this policy, I think the representor solution should be
a real port, not only "for the purposes of control and monitoring".
It has been asked several times as replies to this series,
but it is kindly ignored, saying it will be thought later.

I don't see a general agreement on this series so far.
