[dpdk-dev] [PATCH v1 66/72] net/mlx5/windows: create flow action dest TIR object

[Ophir Munk]

This commit implements mlx5_flow_os_create_flow_action_dest_devx_tir()
API as the Linux rdma-core equivalent. Missing rdma-core parameters are
added to file mlx5_win_defs.h. The action TIR id and type
(MLX5_FLOW_CONTEXT_DEST_TYPE_TIR) are saved in the action struct.  The
action struct will be added to array of actions and will be used later
by the flow creation API.
