From 4244db1b0b7bc9ab7b67d8c1c38de6cf15bc87a8 Mon Sep 17 00:00:00 2001 From: Phoebe Buckheister Date: Mon, 17 Feb 2014 11:34:14 +0100 Subject: 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.
