1959  *
1960  * Routine to be called during initialization of communications with

1962  * the adapter first boots up, it examines attached drives, etc, and
1963  * potentially comes up with a new or revised configuration (relative to
1964  * what's stored in it's NVRAM). Additionally it may discover problems
1965  * that make the current physical configuration unworkable (currently
1966  * applicable only to cluster configuration issues).
1967  *
1968  * If there are no configuration issues or the issues are considered
1969  * trival by the adapter, it will set it's configuration status to
1970  * "FSACT_CONTINUE" and execute the "commit confiuguration" action
1971  * automatically on it's own.
1972  *
1973  * However, if there are non-trivial issues, the adapter will set it's
1974  * internal configuration status to "FSACT_PAUSE" or "FASCT_ABORT"
1975  * and wait for some agent on the host to issue the "\ContainerCommand
1976  * \VM_ContainerConfig\CT_COMMIT_CONFIG" FIB command to cause the
1977  * adapter to commit the new/updated configuration and enable
1978  * un-inhibited operation.  The host agent should first issue the
1979  * "\ContainerCommand\VM_ContainerConfig\CT_GET_CONFIG_STATUS" FIB
1980  * command to obtain information about config issues detected by
1981  * the adapter.
1982  *
1983  * Normally the adapter's PC BIOS will execute on the host following
1984  * adapter poweron and reset and will be responsible for querring the
1985  * adapter with CT_GET_CONFIG_STATUS and issuing the CT_COMMIT_CONFIG
1986  * command if appropriate.
1987  *
1988  * However, with the introduction of IOP reset support, the adapter may
1989  * boot up without the benefit of the adapter's PC BIOS host agent.
1990  * This routine is intended to take care of these issues in situations
1991  * where BIOS doesn't execute following adapter poweron or reset.  The
1992  * CT_COMMIT_CONFIG command is a no-op if it's already been issued, so
1993  * there is no harm in doing this when it's already been done.
