David, you need a feedback from other guys to apply this patch, right? Alexei wanted some output before/after the patch. Michael Ellerman wanted the explanation what a BPF_ANC | SKF_AD_PKTTYPE means. So I'm waiting the ack/nack from them...
I don't really think performance metrics are necessary just for adding SKF_AD_PKTTYPE support, that's sort of an over the top requirement if you ask me. It's pretty obvious that we should support as many operations as possible to each JIT, because all of program has to do is use that unsupported opcode and then we have none of that program being JIT'd.
