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.
