> Subject: [PATCH v3] net/mlx5: handle MPRQ incompatibility with external
> buffers
>
> Multi-Packet Rx queue uses PMD-managed buffers to store packets.
> These buffers are externally attached to user mbufs.
> This conflicts with the feature that allows using user-managed externally
> attached buffers in an application.
> Fall back to SPRQ in case external buffers mempool is configured.
> Add the corresponding limitation to MLX5 documentation that MPRQ and
> external data buffers cannot be used together.
