+  * @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_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
++ *    rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
++ *    and @NL80211_ATTR_TX_RATES the set of allowed rates.
++ *
