IB/core: Expose RSS related capabilities
Expose RSS related capabilities, it includes both direct ones (i.e. struct ib_rss_caps) and max_wq_type_rq which may be used in both RSS and non RSS flows. Specifically, supported_qpts: - QP types that support RSS on the device. max_rwq_indirection_tables: - Max number of receive work queue indirection tables that could be opened on the device. max_rwq_indirection_table_size: - Max size of a receive work queue indirection table. max_wq_type_rq: - Max number of work queues of receive type that could be opened on the device.
