From: Dave Marquardt <[email protected]> Implement support for extended FPIN messages received via the asynchronous sub-queue, completing full FPIN functionality.
Extended FPIN messages provide more detailed information about fabric events compared to basic FPIN messages, including specific event types, modifiers, thresholds, event counts, and severity. Add ibmvfc_ext_fpin_to_desc() to convert extended FPIN messages from async sub-queue format to fc_els_fpin structures with complete descriptor information. Thread detecting_wwpn (fc_host_port_name()) through ibmvfc_ext_fpin_to_desc() to ibmvfc_common_fpin_to_desc() consistent with ibmvfc_basic_fpin_to_desc() and ibmvfc_full_fpin_to_desc(). Update ibmvfc_process_async_work() and ibmvfc_handle_async() to zero node_name and dispatch to ibmvfc_ext_fpin_to_desc() when the IBMVFC_ASYNC_IS_FPIN_EXT flag is set. Extend ibmvfc_common_fpin_to_desc() with a severity parameter so that extended FPIN events can propagate the severity value from the VIOS when IBMVFC_FPIN_SEVERITY_VALID is set, rather than always defaulting to FPIN_CONGN_SEVERITY_WARNING. Severity is only carried by the congestion descriptor used for IBMVFC_AE_FPIN_LINK_CONGESTED and IBMVFC_AE_FPIN_CONGESTION_CLEARED; the peer congestion and link integrity descriptors have no severity field, so a severity supplied for the other FPIN statuses is ignored. Set the IBMVFC_CAN_HANDLE_FPIN_EXT capability bit (0x800) during login to inform the VIOS that the client can process extended FPIN messages. Add the IBMVFC_CAN_CLS_CRQ_PRE_DMP capability bit (0x400) definition for the intervening protocol-defined capability. Also add the IBMVFC_SUPPORT_FPIN_EXT response capability bit definition used to gate extended FPIN processing. In ibmvfc_process_async_work(), use goto to bypass the generic "FPIN event received, unable to process" error message when a more specific diagnostic has already been emitted for invalid or unsupported extended FPIN events. Add a KUnit test, ibmvfc_extended_fpin_test(), that sends extended FPIN events through ibmvfc_process_async_work() for each FPIN status with the event types valid for that status, setting only IBMVFC_FPIN_EVENT_TYPE_VALID, and checks that the matching fc_host or rport FPIN statistic is incremented. The test is skipped if no ibmvfc device, online target rport, or IBMVFC_SUPPORT_FPIN_EXT capability is available. It does not exercise the modifier, threshold, severity or event count fields, nor the error paths for a missing IBMVFC_FPIN_EVENT_TYPE_VALID flag or an unadvertised IBMVFC_SUPPORT_FPIN_EXT capability.
