- * PURPOSE: The purpose of this function is to control

- * Allocations are limited to the primary FDDI ring.
- * The SBM provides recovery mechanisms to recover
- * unused bandwidth also resolves T_Neg and
- * reconfiguration changes. Many of the SBM state
- * machine inputs are sourced by the underlying
