    cfg80211: track monitor interfaces count · dbbae26a
    Michal Kazior authored
    Implements .set_monitor_enabled(wiphy, enabled).
    Notifies driver upon change of interface layout.
    If only monitor interfaces become present it is
    called with 2nd argument being true. If
    non-monitor interface appears then 2nd argument
    is false. Driver is notified only upon change.
    This makes it more obvious about the fact that
    cfg80211 supports single monitor channel. Once we
    implement multi-channel we don't want to allow
    setting monitor channel while other interface
    types are running. Otherwise it would be ambiguous
    once we start considering num_different_channels.
