From: Michael Baum
> These patches add support to external Rx queues.
> External queue is a queue that is managed by a process external to PMD, but
> uses PMD process to generate its flow rules.
>
> For the hardware to allow the DPDK process to set rules for it, the process
> needs
> to use the same PD of the external process. In addition, the indexes of the
> queues in hardware are represented by 32-bit compared to the rte_flow indexes
> represented by 16-bit, so the processes need to share some mapping between
> the indexes.
>
> These patches allow the external process to provide devargs which enable
> importing its context and PD, instead of prepare new ones. In addition, an
> API is
> provided for mapping for the indexes of the queues.
>
> v2:
> - Rebase.
> - Add ABI exception for common/mlx5 library.
> - Correct DevX flag updating.
> - Improve explanations in doc and comments.
> - Remove teatpmd part.
