* vendor subcommand to trigger channel utilization measurement on entire

* channel utilization measurement shall be done on all the MLO links.
* The driver may use regular scan or wideband energy detection feature
* based on the hardware capability for connected channel(s) utilization
* measurement. The driver indicates the connected channel(s) utilization
* measurement completion as an asynchronous event with this command ID to
* userspace. Upon receiving this event, userspace can use
* %NL80211_CMD_GET_INTERFACE to determine the channel width of the current
* connected channel(s) and can derive the channel utilization percentage
* (CU) of each 20 MHz sub-channel of the entire connected channel using
* %NL80211_CMD_GET_SURVEY response.
* CU = %NL80211_SURVEY_INFO_TIME_BUSY * 100 / %NL80211_SURVEY_INFO_TIME.
* This command is only used for STA mode.
