cycling layer. This definition was previously held in net/mac/mac.h, with the name MAC_CONF_CHANNEL_CHECK_RATE. But since the rate is used by the radio duty cycling layer, it makes more sense to change its name to reflect this. Also, the configuration option should be tied to the netstack configuration instead. So the new configuration option is called NETSTACK_CONF_RDC_CHANNEL_CHECK_RATE.
