> Subject: [PATCH] common/mlx5: fix MR lookup on slow path
>
> Memory region (MR) was being looked up incorrectly for the data address of
> an externally-attached mbuf.
> A search was attempted for the mempool of the mbuf, while mbuf data
> address does not belong to this mempool in case of externally-attached mbuf.
> Only attempt the search:
> 1) for not externally-attached mbufs;
> 2) for mbufs coming from MPRQ mempool;
> 3) for externally-attached mbufs from mempools
> with pinned external buffers.
