    cfg80211: add remain-on-channel command · 9588bbd5
    Jouni Malinen authored
    Add new commands for requesting the driver to remain awake
    on a specified channel for the specified amount of time
    (and another command to cancel such an operation). This
    can be used to implement userspace-controlled off-channel
    operations, like Public Action frame exchange on another
    channel than the operation channel.
    The off-channel operation should behave similarly to scan,
    i.e. the local station (if associated) moves into power
    save mode to request the AP to buffer frames for it and
    then moves to the other channel to allow the off-channel
    operation to be completed. The duration parameter can be
    used to request enough time to receive a response from
    the target station.
