2666  * The following function comes from Adaptec:
2667  *
2668  * Routine to be called during initialization of communications with
2669  * the adapter to handle possible adapter configuration issues. When
2670  * the adapter first boots up, it examines attached drives, etc, and
2671  * potentially comes up with a new or revised configuration (relative to
2672  * what's stored in it's NVRAM). Additionally it may discover problems
2673  * that make the current physical configuration unworkable (currently
2674  * applicable only to cluster configuration issues).
2675  *
2676  * If there are no configuration issues or the issues are considered
2677  * trival by the adapter, it will set it's configuration status to
2678  * "FSACT_CONTINUE" and execute the "commit confiuguration" action
2679  * automatically on it's own.
2680  *
2681  * However, if there are non-trivial issues, the adapter will set it's
2682  * internal configuration status to "FSACT_PAUSE" or "FASCT_ABORT"
2683  * and wait for some agent on the host to issue the "\ContainerCommand
2684  * \VM_ContainerConfig\CT_COMMIT_CONFIG" FIB command to cause the
2685  * adapter to commit the new/updated configuration and enable
2686  * un-inhibited operation.  The host agent should first issue the
2687  * "\ContainerCommand\VM_ContainerConfig\CT_GET_CONFIG_STATUS" FIB
2688  * command to obtain information about config issues detected by
2689  * the adapter.
2690  *
2691  * Normally the adapter's PC BIOS will execute on the host following
2692  * adapter poweron and reset and will be responsible for querring the
2693  * adapter with CT_GET_CONFIG_STATUS and issuing the CT_COMMIT_CONFIG
2694  * command if appropriate.
2695  *
2696  * However, with the introduction of IOP reset support, the adapter may
2697  * boot up without the benefit of the adapter's PC BIOS host agent.
2698  * This routine is intended to take care of these issues in situations
2699  * where BIOS doesn't execute following adapter poweron or reset.  The
2700  * CT_COMMIT_CONFIG command is a no-op if it's already been issued, so
2701  * there is no harm in doing this when it's already been done.
