/**
* enum iwl_mvm_vendor_cmd - supported vendor commands
* @IWL_MVM_VENDOR_CMD_GET_CSME_CONN_INFO: reports CSME connection info.
* @IWL_MVM_VENDOR_CMD_HOST_GET_OWNERSHIP: asks for ownership on the device.
* This is useful when the CSME firmware owns the device and the kernel
* wants to use it. In case the CSME firmware has no connection active the
* kernel will manage on its own to get ownership of the device.
* When the CSME firmware has an active connection, the user space
* involvement is required. The kernel will assert the RFKILL signal with
* the "device not owned" reason so that nobody can touch the device. Then
* the user space can run the following flow to be able to get connected
* to the very same AP the CSME firmware is currently connected to:
*
* 1) The user space (NetworkManager) boots and sees that the device is
* in RFKILL because the host doesn't own the device
* 2) The user space asks the kernel what AP the CSME firmware is
* connected to (with %IWL_MVM_VENDOR_CMD_GET_CSME_CONN_INFO)
* 3) The user space checks if it has a profile that matches the reply
* from the CSME firmware
* 4) The user space installs a network to the wpa_supplicant with a
* specific BSSID and a specific frequency
* 5) The user space prevents any type of full scan
* 6) The user space asks iwlmei to request ownership on the device (with
* this command)
* 7) iwlmei requests ownership from the CSME firmware
* 8) The CSME firmware grants ownership
* 9) iwlmei tells iwlwifi to lift the RFKILL
* 10) RFKILL OFF is reported to user space
* 11) The host boots the device, loads the firwmare, and connects to a
* specific BSSID without scanning including IP as fast as it can
* 12) The host reports to the CSME firmware that there is a connection
* 13) The TCP connection is preserved and the host has connectivity
*
* @IWL_MVM_VENDOR_CMD_ROAMING_FORBIDDEN_EVENT: notifies if roaming is allowed.
* It contains a &IWL_MVM_VENDOR_ATTR_ROAMING_FORBIDDEN and a
* &IWL_MVM_VENDOR_ATTR_VIF_ADDR attributes.
