};
- NVME_CTRL_CMIC_MULTI_PORT
- If set, then the NVM subsystem may contain more than one
NVM subsystem port, otherwise the NVM subsystem contains only a single NVM
subsystem port.
- NVME_CTRL_CMIC_MULTI_CTRL
- If set, then the NVM subsystem may contain two or more
controllers, otherwise the NVM subsystem contains only a single
controller. An NVM subsystem that contains multiple controllers may be
used by multiple hosts, or may provide multiple paths for a single
host.
- NVME_CTRL_CMIC_MULTI_SRIOV
- If set, then the controller is associated with an SR-IOV
Virtual Function, otherwise it is associated with a PCI Function or a
Fabrics connection.
- NVME_CTRL_CMIC_MULTI_ANA_REPORTING
- If set, then the NVM subsystem supports Asymmetric
Namespace Access Reporting.
