Current DPDK 21.11 flow API does not support RTE_FLOW_ITEM_TYPE_RAW for
MLX5.

I need support of RTE_FLOW_ITEM_TYPE_RAW in DPDK flow API to enqueue some
ingress packets by content to GPU with support of GPUDirect RDMA and other
to CPU via distinct HW queues (RTE_FLOW_ACTION_TYPE_QUEUE).

For now RTE_FLOW_ITEM_TYPE_UDP and RTE_FLOW_ITEM_TYPE_IPV4 filtering and
enqueueing with address and ports are supported.

Are there any plans to support RTE_FLOW_ITEM_TYPE_RAW for MLX5?
