    ieee802154: add netlink APIs for smartMAC configuration · 4244db1b
    Phoebe Buckheister authored
    Introduce new netlink attributes for SET_PHY_ATTRS:
     * CSMA minimal backoff exponent
     * CSMA maximal backoff exponent
     * CSMA retry limit
     * frame retransmission limit
    
    The CSMA attributes shall correspond to minBE, maxBE and maxCSMABackoffs of
    802.15.4, respectively. The frame retransmission shall correspond to
    maxFrameRetries of 802.15.4, unless given as -1: then the old behaviour
    of the stack shall apply. For RF2xy, the old behaviour is to not do
    channel sensing at all and simply send *right now*, which is not
    intended behaviour for most applications and actually prohibited for
    some channel/page combinations.
    
    For all values except frame retransmission limit, the defaults of
    802.15.4 apply. Frame retransmission limits are set to -1 to indicate
    backward-compatible behaviour.
