bpf: Sample BPF program to set buffer sizes 2017-07-01T23:15:14+00:00 Lawrence Brakmo brakmo@fb.com 2017-07-01T03:02:48+00:00 d9925368a641391f38cd281e67b948e6b6f3bcca This patch contains a BPF program to set initial receive window to 40 packets and send and receive buffers to 1.5MB. This would usually be done after doing appropriate checks that indicate the hosts are far enough away (i.e. large RTT). Signed-off-by: Lawrence Brakmo <brakmo@fb.com> Signed-off-by: David S.
