This feature gives users the ability to use Route Control Functions (RCFs) to create custom policies for deciding which routes with IP next-hops should be programmed into the kernel with fwd* next-hop devices so the associated kernel packets are inserted into the ingress pipeline of hardware forwarding instead of being software-forwarded by the kernel.
