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.
