Hi

Thanks for the post, that seems like an interesting way to do
high-performance forwarding. Is is possible to use this approach when a
packet is forwarded between NICs (or at least between multiple ports on
one NIC)?

So it seems there are at least three ways how to do high-performance
forwarding with Linux and BIRD:

1) White-box routers with hardware forwarding plane

2) VPP dataplane

3) tc-based rules that are offloaded to NIC
