From ae531b9475f62c5e1863508604cd6b3faf362d56 Mon Sep 17 00:00:00 2001 From: Phoebe Buckheister Date: Fri, 14 Mar 2014 21:24:02 +0100 Subject: [PATCH] ieee802154: use ieee802154_addr instead of *_sa variants Change all internal uses of ieee802154_addr_sa to ieee802154_addr, except for those instances that communicate directly with userspace.
