> Subject: [PATCH] crypto/ipsec_mb: fix allocating mb_mgr in session
>
> When configuring the session, use the queue pair mb_mgr that was already
> allocated if possible. If this doesn't exist, then allocate a new mb_mgr.
>
> This reduces unnecessary cycles creating an mb_mgr for every session
> configured.
