IB/core: Convert core to use bitfield for caps
Remove query_protocol callback Use the new Core Capability bits for: rdma_protocol_* rdma_cap_ib_mad rdma_cap_ib_smi rdma_cap_ib_cm rdma_cap_iw_cm rdma_cap_ib_sa rdma_cap_ib_mcast rdma_cap_af_ib rdma_cap_eth_ah Signed-off-by: Ira Weiny <ira.weiny@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
