As mentioned in the other thread:

We need to urgently decide if this bug should live on in DPDK 23.11, or if the fix should be included although we are very late in the release process.

Stanislaw, what do you think?

Furthermore, I wonder if it can be backported to stable, and to what extent backporting it would break the ABI/API.
