net/mlx5: enable secondary process to register DMA memory
The Memory Region (MR) for DMA memory can't be created from secondary process due to lib/driver limitation. Whenever it is needed, secondary process can make a request to primary process through the EAL IPC channel (rte_mp_msg) which is established on initialization. Once a MR is created by primary process, it is immediately visible to secondary process because the MR list is global per a device. Thus, secondary process can look up the list after the request is successfully returned. Signed-off-by: Yongseok Koh <yskoh@mellanox.com> Acked-by: Shahaf Shuler <shahafs@mellanox.com>
