- 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.
- tsas
- Transport specific attribute settings
