6.10 removed the "support" (it was never supported [1]) of separate
source and build dirs for out of tree modules.
KNI uses "src=" hack for that purpose.
Instead, copy sources to the build dir and don't rely upon the
unsupported...
Intended esp. for stable/22.11. It should go wherever kni is still in
the tree.

Adding stable@dpdk.org and LTS maintainers as Cc.
It must be merged directly in LTS branches.

Hi Jiri,
Please follow the process described in the "stable release" paragraph at:
https://core.dpdk.org/contribute/
ie, one patch per affected LTS branch must be prepared, tested and
sent individually, and then we'll apply it. Thanks.
