From 13bf96411ad2bd162a4f9470d58c6bb579c96e21 Mon Sep 17 00:00:00 2001 From: Lawrence Brakmo Date: Fri, 30 Jun 2017 20:02:53 -0700 Subject: bpf: Adds support for setting sndcwnd clamp Adds a new bpf_setsockopt for TCP sockets, TCP_BPF_SNDCWND_CLAMP, which sets the initial congestion window. It is useful to limit the sndcwnd when the host are close to each other (small RTT). Signed-off-by: Lawrence Brakmo Signed-off-by: David S.
