IMHO the kernel parts have to be available in a released kernel version.
Otherwise the kernel API/ABI is not stable and there is a possibility of user
confusion.
This needs to stay in "awaiting upstream" state until kernel is released
Sorry, it's a typo. The dependent kernel is 6.12 which is in RC. Do you
think we should wait for it to be released to push the patch to DPDK
upstream?
