> Subject: [PATCH] doc: abstract the behaviour of rte_ctrl_thread_create
>
> The current expected behaviour of the function rte_ctrl_thread_create is
> rigid which makes the implementation of the function complex.
> Make the expected behaviour abstract to allow for simplified
> implementation.
>
> With this change, the calls to pthread_setaffinity_np can be moved to the
> control thread. This will avoid the use of pthread_barrier_wait and simplify
> the synchronization mechanism between rte_ctrl_thread_create and the
> calling thread.
