[NVME\_CTRL\_CMIC\_MULTI\_PORT](#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](#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](#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.
