From: https://patchwork.ozlabs.org/patch/396713/ https://patchwork.ozlabs.org/patch/396713/ From: Daniel Borkmann ... With 1 core netmap does 10G line-rate on 64b; I don't know their numbers on 40G when run on decent hardware though. So looks like netmap has not only nice API, driver-specific code is trivial, but also the performance might be good. If only netmap could do the "bifurcated driver" use case!
