ieee802154: fix byteorder for short address and panid
This patch changes the byteorder handling for short and panid handling. We now except to get little endian in nl802154 for these attributes. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
