Members

       structure_id
                   Structure   ID:   This   field   shall   be   set   to   6h   (i.e.,   Discovery  Descriptor;
                   #NBFT_DESC_DISCOVERY).

       flags       Discovery Descriptor Flags, see enum nbft_discovery_flags.

       index       Discovery Descriptor Index: This field indicates the number of this Discovery  Descriptor  in
                   the Discovery Descriptor List.

       hfi_index   HFI Descriptor Index: This field indicates the value of the HFI Descriptor Index field of the
                   HFI Descriptor associated with this Discovery Descriptor. If multiple  HFIs  share  a  common
                   Discovery controller, there shall be multiple Discovery Descriptor entries with one per HFI.

       sec_index   Security  Profile  Descriptor  Index:  This field indicates the value of the Security Profile
                   Descriptor Index field of the Security Descriptor associated with this Discovery Descriptor.

       reserved1   Reserved.

       discovery_ctrl_addr_obj
                   Discovery Controller Address Heap Object Reference: This field  indicates  the  location  and
                   size  of  a  heap  object  containing  a  URI  which  indicates  an NVMe Discovery controller
                   associated with this Discovery Descriptor.  If this field is cleared to 0h, then  no  URI  is
                   specified.

       discovery_ctrl_nqn_obj
                   Discovery  Controller  NQN  Heap  Object  Reference:  If  set to a non-zero value, this field
                   indicates the location and size of a heap object containing an NVMe Discovery controller NQN.
                   If  the  NVMe  Discovery  controller referenced by this record requires secure authentication
                   with a well known Subsystem NQN, this field indicates the unique NQN for that NVMe  Discovery
                   controller.  This  record is involved formatted as an NQN string. If this field is cleared to
                   0h, then this field is reserved and the OS shall use the well known discovery  NQN  for  this
                   record.

       reserved2   Reserved.
