ieee802154: add netlink APIs for smartMAC configuration
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.
