Members

       trtype      Transport  Type  (TRTYPE):  Specifies  the  NVMe  Transport  type.   See  enum
                   nvmf_trtype.

       adrfam      Address  Family  (ADRFAM):   Specifies   the   address   family.    See   enum
                   nvmf_addr_family.

       subtype     Subsystem  Type  (SUBTYPE):  Specifies  the  type of the NVM subsystem that is
                   indicated in this entry. See enum nvme_subsys_type.

       treq        Transport Requirements (TREQ): Indicates requirements for the NVMe  Transport.
                   See enum nvmf_treq.

       portid      Port  ID  (PORTID): Specifies a particular NVM subsystem port.  Different NVMe
                   Transports or address families may utilize the same Port ID value (e.g. a Port
                   ID may support both iWARP and RoCE).

       cntlid      Controller ID (CNTLID): Specifies the controller ID. If the NVM subsystem uses
                   a dynamic controller model, then this field shall be set to FFFFh. If the  NVM
                   subsystem  uses  a  static  controller  model, then this field may be set to a
                   specific controller ID (values 0h to FFEFh are valid). If  the  NVM  subsystem
                   uses a static controller model and the value indicated is FFFEh, then the host
                   should remember the Controller ID returned as  part  of  the  Fabrics  Connect
                   command  in  order  to re-establish an association in the future with the same
                   controller.

       asqsz       Admin Max SQ Size (ASQSZ): Specifies the maximum size of an  Admin  Submission
                   Queue.  This  applies to all controllers in the NVM subsystem. The value shall
                   be a minimum of 32 entries.

       eflags      Entry Flags (EFLAGS): Indicates additional information related to the  current
                   entry. See enum nvmf_disc_eflags.

       rsvd12      Reserved

       trsvcid     Transport  Service  Identifier (TRSVCID): Specifies the NVMe Transport service
                   identifier as an ASCII  string.  The  NVMe  Transport  service  identifier  is
                   specified by the associated NVMe Transport binding specification.

       rsvd64      Reserved

       subnqn      NVM Subsystem Qualified Name (SUBNQN): NVMe Qualified Name (NQN) that uniquely
                   identifies the NVM subsystem. For a subsystem, if that Discovery subsystem has
                   a  unique  NQN  (i.e., the NVM Subsystem NVMe Qualified Name (SUBNQN) field in
                   that Discovery subsystem's  Identify  Controller  data  structure  contains  a
                   unique  NQN  value),  then the value returned shall be that unique NQN. If the
                   Discovery subsystem does not have a unique NQN, then the value returned  shall
                   be         the         well-known         Discovery         Service        NQN
                   (nqn.2014-08.org.nvmexpress.discovery).

       traddr      Transport Address (TRADDR): Specifies the address of the  NVM  subsystem  that
                   may be used for a Connect command as an ASCII string. The Address Family field
                   describes the reference for parsing this field.
