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. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
