How can routing protocols such as OSPF and RIP use the network layer

Network Engineering

I understand that one of the responsibilities (services) of the network layer is to provide host to host delivery of data and to achieve that goal the network layer uses routing protocols to populate forwarding tables in order for routers to know where to send data. The UDP segment is carried between routers in a standard IP data- gram.

I'm also curious, if I use eBPF to offload this forwarding, can I let the packets go through the protocol stack to avoid the above situation? Please correct me.
