  * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
  *      associated with this wiphy must be down and will follow.
  *
+ * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
+ *      channel for the specified amount of time. This can be used to do
+ *      off-channel operations like transmit a Public Action frame and wait for
+ *      a response while being associated to an AP on another channel.
+ *      %NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify which
+ *      radio is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
+ *      frequency for the operation and %NL80211_ATTR_WIPHY_CHANNEL_TYPE may be
+ *      optionally used to specify additional channel parameters.
+ *      %NL80211_ATTR_DURATION is used to specify the duration in milliseconds
+ *      to remain on the channel. This command is also used as an event to
+ *      notify when the requested duration starts (it may take a while for the
+ *      driver to schedule this time due to other concurrent needs for the
+ *      radio).
+ *      When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
+ *      that will be included with any events pertaining to this request;
+ *      the cookie is also used to cancel the request.
+ * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
+ *      pending remain-on-channel duration if the desired operation has been
+ *      completed prior to expiration of the originally requested duration.
+ *      %NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
+ *      radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
+ *      uniquely identify the request.
+ *      This command is also used as an event to notify when a requested
+ *      remain-on-channel duration has expired.

  * @NL80211_CMD_MAX: highest used command number
