From ba08fea53a43e02b590d89224afdad976dece841 Mon Sep 17 00:00:00 2001 From: Phoebe Buckheister Date: Mon, 17 Feb 2014 11:34:11 +0100 Subject: ieee802154: add support for CCA mode in wpan phys The standard describes four modes of clear channel assesment: "energy above threshold", "carrier found", and the logical and/or of these two. Support for CCA mode setting is included in the at86rf230 driver, predicated for RF212 chips. Signed-off-by: Phoebe Buckheister Signed-off-by: David S.
