This patch adds new HCA capability related to hairpin RQs. This new capability, hairpin_data_buffer_locked, indicates whether HCA supports locking data buffer of hairpin RQ in ICMC (Interconnect Context Memory Cache). Struct used to define RQ configuration (RQ context) is extended with hairpin_data_buffer_type field, which configures data buffer for hairpin RQ. It can take the following values: - MLX5_RQC_HAIRPIN_DATA_BUFFER_TYPE_UNLOCKED_INTERNAL_BUFFER - hairpin RQ's data buffer is stored in unlocked memory in ICMC. - MLX5_RQC_HAIRPIN_DATA_BUFFER_TYPE_LOCKED_INTERNAL_BUFFER - hairpin RQ's data buffer is stored in locked memory in ICMC.
