    cfg80211: add channel switch started notification · f8d7552e
    Luciano Coelho authored
    Add a new NL80211_CH_SWITCH_STARTED_NOTIFY message that can be sent to
    the userspace when a channel switch process has started.  This allows
    userspace to take action, for instance, by requesting other interfaces
    to switch channel as necessary.
    This patch introduces a function that allows the drivers to send this
    notification.  It should be used when the driver starts processing a
    channel switch initiated by a remote device (eg. when a STA receives a
    CSA from the AP) and when it successfully starts a userspace-triggered
    channel switch (eg. when hostapd triggers a channel swith in the AP).
