> feature
> 
> Modify API mlx5_flow_dev_dump to support the feature.
> Modify mlx5_socket since one extra arg flow_ptr is added.
> 
> The data structure sent to DPDK application from the utility triggering the
> flow dumps should be packed and endianness must be specified.
> The native host endianness can be used, all exchange happens within the
> same host (we use sendmsg aux data and share the file handle, remote
> approach is not applicable, no inter-host communication happens).
> 
> The message structure to dump one/all flow(s):
> struct mlx5_flow_dump_req {
> 	uint32_t port_id;
> 	uint64_t flow_ptr;
> } __rte_packed;
> 
> If flow_ptr is 0, all flows for the specified port will be dumped.
