struct nvmf_disc_log_entry - Discovery Log Page entry

trtype Transport Type (TRTYPE): Specifies the NVMe Transport type. See enumnvmf_trtype. adrfam Address Family (ADRFAM): Specifies the address family. See enumnvmf_addr_family. subtype Subsystem Type (SUBTYPE): Specifies the type of the NVM subsystem that is indicated in this entry. See enumnvme_subsys_type. treq Transport Requirements (TREQ): Indicates requirements for the NVMe Transport. See enumnvmf_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 enumnvmf_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 August 2025 struct nvmf_disc_log_entry libnvme(2)
