From 84dda3c648fd55898064d76366b14f964cdc9d16 Mon Sep 17 00:00:00 2001 From: Phoebe Buckheister Date: Mon, 17 Feb 2014 11:34:10 +0100 Subject: ieee802154: add support for listen-before-talk in wpan_phy Listen-before-talk is an alternative to CSMA in uncoordinated networks and prescribed by european regulations if one wants to have a device with radio duty cycles above 10% (or less in some bands). Add a phy property to enable/disable LBT in the phy, including support in the at86rf230 driver for RF212 chips. Signed-off-by: Phoebe Buckheister Signed-off-by: David S.
