Members

       structure_id
                   Structure  ID:  This  field  specifies the element (refer to enum nbft_desc_type). This field
                   shall be set to 1h (i.e., Control, #NBFT_DESC_CONTROL).

       major_revision
                   Major Revision: The major revision of the structure corresponding  to  the  Signature  field.
                   Larger  major  revision  numbers  should  not  be  assumed backward compatible to lower major
                   revision numbers with the same signature.

       minor_revision
                   Minor Revision: The minor revision of the structure corresponding to the signature field.  If
                   the  major  revision  numbers  are  the  same, any minor revision number differences shall be
                   backwards compatible with the same signature.

       reserved1   Reserved.

       csl         Control Structure Length (CSL): This field indicates the  length  in  bytes  of  the  Control
                   Descriptor.

       flags       Flags, see enum nbft_control_flags.

       reserved2   Reserved.

       hdesc       Host  Descriptor (HDESC): This field indicates the location and length of the Host Descriptor
                   (see struct nbft_host).

       hsv         Host Descriptor Version (HSV): This field indicates the version of the Host Descriptor.

       reserved3   Reserved.

       hfio        HFI Descriptor List Offset (HFIO): If this field is set to a non-zero value, then this  field
                   indicates  the offset in bytes of the HFI Descriptor List, if any, from byte offset 0h of the
                   NBFT Table Header. If the num_hfi field is cleared to 0h, then this field is reserved.

       hfil        HFI Descriptor Length  (HFIL):  This  field  indicates  the  length  in  bytes  of  each  HFI
                   Descriptor, if any. If the num_hfi field is cleared to 0h, then this field is reserved.

       hfiv        HFI Descriptor Version (HFIV): This field indicates the version of each HFI Descriptor.

       num_hfi     Number  of Host Fabric Interface Descriptors (NumHFI): This field indicates the number of HFI
                   Descriptors (see struct nbft_hfi) in the HFI Descriptor List, if any. If no  interfaces  have
                   been configured, then this field shall be cleared to 0h.

       ssnso       SSNS  Descriptor  List  Offset (SSNSO):: This field indicates the offset in bytes of the SSNS
                   Descriptor List, if any, from byte offset 0h of the NBFT Table Header. If the num_ssns  field
                   is cleared to 0h, then this field is reserved.

       ssnsl       SSNS  Descriptor  Length  (SSNSL):  This  field  indicates  the  length in bytes of each SSNS
                   Descriptor, if any. If the num_ssns field is cleared to 0h, then this field is reserved.

       ssnsv       SSNS Descriptor Version (SSNSV): This field indicates the version of the SSNS Descriptor.

       num_ssns    Number of Subsystem and Namespace Descriptors (NumSSNS): This field indicates the  number  of
                   Subsystem Namespace (SSNS) Descriptors (see struct nbft_ssns) in the SSNS Descriptor List, if
                   any.

       seco        Security Profile Descriptor List Offset (SECO): This field indicates the offset in  bytes  of
                   the  Security  Profile Descriptor List, if any, from byte offset 0h of the NBFT Table Header.
                   If the num_sec field is cleared to 0h, then this field is reserved.

       secl        Security Profile Descriptor Length (SECL): This field indicates the length in bytes  of  each
                   Security  Profile Descriptor, if any.  If the num_sec field is cleared to 0h, then this field
                   is reserved.

       secv        Security Profile Descriptor Version (SECV): This field indicates the version of the  Security
                   Profile Descriptor.

       num_sec     Number  of Security Profile Descriptors (NumSec): This field indicates the number of Security
                   Profile Descriptors (see struct nbft_security), if any, in the  Security  Profile  Descriptor
                   List.

       disco       Discovery  Descriptor  Offset  (DISCO):  This  field  indicates  the  offset  in bytes of the
                   Discovery Descriptor List, if any, from byte offset 0h of  the  NBFT  Table  Header.  If  the
                   num_disc field is cleared to 0h, then this field is reserved.

       discl       Discovery  Descriptor  Length  (DISCL):  This  field  indicates  the  length in bytes of each
                   Discovery Descriptor, if any.  If the num_disc field is cleared to 0h,  then  this  field  is
