From 344f8c119df742f2bf7098cf8fc326351f583249 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Fri, 22 May 2015 17:43:53 +0200 Subject: mac802154: use atomic ops for sequence incrementation This patch will use atomic operations for sequence number incrementation while MAC header generation. Upper layers like af_802154 or 6LoWPAN could call this function in a parallel context while generating 802.15.4 MAC header before queuing into wpan interfaces transmit queue.
