Your assumptions are correct, recv count is the number of packets which are
received by the bpf peer, match count is the number of packets which matched
the bpf filter that is active.. this shouldn’t be happening. Are you running
netstat during the tcpreplay run or after it completed? Also can y

Guy,
Can you please describe the race and how to reproduce it? When we introduced
zerocopy-bpf, we also introduced bpf_bufheld() and bpf_bufreclaimed() which are

I would like to propose a change for tun(4) but before I do, I would like to
read any feedback this list might have. Basically we have a situation where
we need to manually configure tunnel interfaces when a process opens them.
We would like to hook into devd(8) for this. i.e. when we see tunX "l
