    cfg80211: allow wiphy specific regdomain management · b0d7aa59
    Jonathan Doron authored
    Add a new regulatory flag that allows a driver to manage regdomain
    changes/updates for its own wiphy.
    A self-managed wiphys only employs regulatory information obtained from
    the FW and driver and does not use other cfg80211 sources like
    beacon-hints, country-code IEs and hints from other devices on the same
    system. Conversely, a self-managed wiphy does not share its regulatory
    hints with other devices in the system. If a system contains several
    devices, one or more of which are self-managed, there might be
    contradictory regulatory settings between them. Usage of flag is
    generally discouraged. Only use it if the FW/driver is incompatible
    with non-locally originated hints.
    
    A new API lets the driver send a complete regdomain, to be applied on
    its wiphy only.
    
    After a wiphy-specific regdomain change takes place, usermode will get
    a new type of change notification. The regulatory core also takes care
    enforce regulatory restrictions, in case some interfaces are on
    forbidden channels.
