From 376b7bd3558eaf12d3e5c24aa71d0c162d2701fd Mon Sep 17 00:00:00 2001
From: Phoebe Buckheister <phoebe.buckheister@itwm.fraunhofer.de>
Date: Fri, 14 Mar 2014 21:23:57 +0100
Subject: ieee802154: rename struct ieee802154_addr to *_sa

The struct as currently defined uses host byte order for some fields,
and most big endian/EUI display byte order for other fields. Inside the
stack, endianness should ideally match network byte order where possible
to minimize the number of byteswaps done in critical paths, but this
patch does not address this; it is only preparatory.
