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 reserved.
discv Discovery Descriptor Version (DISCV): This field indicates the version of the
Discovery Descriptor.
num_disc Number of Discovery Descriptors (NumDisc): This field indicates the number of
Discovery Descriptors (see struct nbft_discovery), if any, in the Discovery
Descriptor List, if any.
reserved4 Reserved.
