Hi Neil,
Thanks for taking the time to reflect on my ideas.

This does seem like an excellent position. It is succinct, it sets
expectations for users, and it tells developers how to resolve trade-offs
(performance takes priority over FOO, for all values of FOO). I agree that
this niche will always be there and so it seems like there is a permanent
place in the world for DPDK.
This focus on performance also makes DPDK useful as a reference for other
projects. People making trade-offs between performance and other factors
(portability, compatibility, simplicity, etc) can use DPDK as a yardstick
to estimate what this costs. This benefits everybody doing networking on
x86.
I suppose that a separate discussion would be how to increase participation
from people who are using DPDK as a reference but not as a software
dependency. That is perhaps a less pressing topic for the future.
OVS is a great example here. If we can make it easy for them to use DPDK

I will be interested to see how this plays out.
I agree it is a great opportunity for DPDK and a chance to take it
mainstream.
I also think it is fundamentally a missed opportunity of the kernel. OVS
would be just fine with a kernel data plane that performs adequately. OVS
users don't seem to be in the "maximum performance at any cost" niche
defined above. Many of them benefit a lot from the kernel integration.
However, if the kernel can't promise the meet their performance
requirements then DPDK does seem like a knight in shining armour.
It's an exciting time in open source networking :-)
Cheers,
-Luke
