How are you running these tests? Still on virtual devices? We really
need results from a physical setup in native mode to assess the impact
on the native-XDP fast path. The numbers above don't tell much in this
regard. I'd also like to see a before/after patch for straight
bpf_redirect_map(), since you're messing with the fast path, and we want
to make sure it's not causing a performance regression for regular
redirect.
Finally, since the overhead seems to be quite substantial: A comparison
with a regular network stack bridge might make sense? After all we also
want to make sure it's a performance win over that :)
