bonding: convert to net_device_ops
Convert to net_device_ops table. Note: for some operations move error checking into generic networking layer (rather than looking at pointers in bonding). A couple of gratituous style cleanups to get rid of extra {} Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
