From ab24f50f2a3e3f6a38b4852530534aa99d86b4d1 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 2 Nov 2014 04:18:40 +0100 Subject: [PATCH] mac802154: add helper for converting dev_addr This patch adds a helper for converting the dev_addr attribute in netdevice to __le64 type. The dev_addr attribute is a char pointer and contains the extended address in big endian byte order.
