According IEEE 802.15.4 standard each node can be either full functionality device (FFD) or reduce functionality device (RFD). So 2 sets of operations are needed. This patch declare RFD operations structure. Signed-off-by: Alexander Smirnov <alex.bluesman.smirnov@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
