[RFC] Remove Kernel Network Interface (KNI)

[Thomas Monjalon]

13/01/2023 06:03, Stephen Hemminger:
> The Linux special network driver for kernel networking has been
> a long term problem for DPDK. The performance benefits of KNI
> are available via virtio-user and XDP, and the simpler kernel
> interface via TAP is also available.
> 
> This driver has required lots of effort to keep up with the
> kernel API changes. And the overall architecture of the driver
> is fundamentally insecure and has unfixable locking and data
> race problems. No developer has been willing to do extensive
> tests or be the maintainer.
> 
> In short, the time has come to do some early spring cleaning
> and remove KNI from DPDK 23.03.

In doc/guides/rel_notes/deprecation.rst it is announced
to be removed in 23.11. Let's keep this RFC for later :)
