[dpdk-dev] [PATCH v5 00/29] Support VFD and DPDK PF + kernel VF on i40e

[Vincent JARDIN]

Thanks John for the kernel support. I'd like to add one thought on this 
need from Joshi:

> Also, the kernel drivers have no concept of passing VF messages to upstream "decision making” (or policy enforcement) software like VFd.

It shall be possible to define some Netlink or policy management 
messages over the PF, so a userland process can police and provide the 
"decision making" in a standard way that would be generic.

Joshi,

John is confirming that the kernel path is possible. Please, if you see 
other requirements, keep listing them.

> However, in theory, this *can* be done through an extra VF as well, so I didn't bring up that particular point as being a deciding factor in this debate.

It remains an important item: it shows that thru the kernel, all 
technical requirements are manageable, including the steering of traffic.

I'll continue the comments on the patch on the v9's thread.
