/**
 * 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.
