Great, thanks. I sent it as RFC initially, because there were some unresolved issues with TC_FROM semantics last time around. bpf_redirect has been merged in the meantime, so I suspect that that has been resolved. But there is no rush. I will run a few more tests, such as the new mirred ingress path, and will hold off resubmitting until people now on holiday have a chance to chime in next week.
