This series moves the classport info query initiation and update from callers such as ipoib to the ib_sa module itself. The classport info cache is updated whenever ib_sa receives an appropriate state change event. Since classport info is only used to check if sendonly full member support is enabled by the SM, we expose a function ib_sa_sendonly_fullmem_support that can be called to check if the support is enabled. Additionally, we introduce support for opa classport info. These are defined specifically for OPA devices and expose additional features in the capability mask bits along with longer LID sizes in some of the other fields. Patch 1 to 3 fix checkpatch issues (1 issue type per patch) on two functions that patch 4 then moves around. Patch 5 makes changes to implicitly query and cache classport info. Patch 6 adds verbs capability API for core layers to query and find out if they are running on an OPA device. Patch 7 moves struct opa_class_port_info to a common header file. Finally, patch 8 adds OPA classport info query support. Changes from v2: --------------- * Add patch 7 that moves struct opa_class_port_info to a common header file Changes from v1: --------------- 1. Initiate Classport Info refresh also on a LID change and SM change events. 2. Make proper use of the 'flags' field in struct ib_sa_query that carries the flag IB_SA_QUERY_OPA. This makes changes to static functions such as alloc_mad and init_mad unnecessary. 3. Remove the unwanted rename of CLASSPORTINFO_REC_FIELD to IB_CLASSPORTINFO_REC_FIELD. 4. Fix the subject prefix. Remove 'rdma-core' from the subject.
