+ * RPMH Fast Path mode

+ * - Fast path mode is a lock-less request transmission to AOSS.
+ * - Requests may be sent from interrupt/scheduler context.
+ * - Dedicated fast-path TCS must be available in the RSC.
+ * - Error returned, when dedicated TCS is not available.
+ * - Only one client is expected to call RPMH fast path.
+ * - Serialization of requests is a responsibility of the client.
+ * - Only active state requests may be made through this mode.
+ * - Sleep/Wake requests for the nodes must be made through
+ *   the standard RPMH APIs (locking modes).
+ * - Fast path requests are not cached and sent immediately.
+ * - Fast path requests are all blocking requests.
+ * - Fast path requests do not use AMC completion interrupts,
+ *   therefore will not receive a tx_done callback.
