2661  * The following function comes from Adaptec:
2662  *
2663  * Routine to be called during initialization of communications with
2664  * the adapter to handle possible adapter configuration issues. When
2665  * the adapter first boots up, it examines attached drives, etc, and
2666  * potentially comes up with a new or revised configuration (relative to
2667  * what's stored in it's NVRAM). Additionally it may discover problems
2668  * that make the current physical configuration unworkable (currently
2669  * applicable only to cluster configuration issues).
2670  *
2671  * If there are no configuration issues or the issues are considered
2672  * trival by the adapter, it will set it's configuration status to
2673  * "FSACT_CONTINUE" and execute the "commit confiuguration" action
2674  * automatically on it's own.
2675  *
2676  * However, if there are non-trivial issues, the adapter will set it's
2677  * internal configuration status to "FSACT_PAUSE" or "FASCT_ABORT"
2678  * and wait for some agent on the host to issue the "\ContainerCommand
2679  * \VM_ContainerConfig\CT_COMMIT_CONFIG" FIB command to cause the
2680  * adapter to commit the new/updated configuration and enable
2681  * un-inhibited operation.  The host agent should first issue the
2682  * "\ContainerCommand\VM_ContainerConfig\CT_GET_CONFIG_STATUS" FIB
2683  * command to obtain information about config issues detected by
2684  * the adapter.
2685  *
2686  * Normally the adapter's PC BIOS will execute on the host following
2687  * adapter poweron and reset and will be responsible for querring the
2688  * adapter with CT_GET_CONFIG_STATUS and issuing the CT_COMMIT_CONFIG
2689  * command if appropriate.
2690  *
2691  * However, with the introduction of IOP reset support, the adapter may
2692  * boot up without the benefit of the adapter's PC BIOS host agent.
2693  * This routine is intended to take care of these issues in situations
2694  * where BIOS doesn't execute following adapter poweron or reset.  The
2695  * CT_COMMIT_CONFIG command is a no-op if it's already been issued, so
2696  * there is no harm in doing this when it's already been done.
