From fea3318d20776a94afeea0460c6ee9904e60569e Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 17 May 2015 21:44:43 +0200 Subject: ieee802154: add several phy supported handling This patch adds support for phy supported handling for all other already existing handling 802.15.4 functionality. We assume now a fully 802.15.4 complaint transceiver at phy allocation. If a transceiver can support 802.15.4 default values only, then the values should be overwirtten by values the transceiver supports. If the transceiver doesn't set the according hardware flags, we assume the 802.15.4 defaults now which cannot be changed.
