From 5d134f1c1f36166e8a738de92c4d2f4c262ff91b Mon Sep 17 00:00:00 2001 From: Hannes Frederic Sowa Date: Sat, 5 Jan 2013 16:10:48 +0000 Subject: tcp: make sysctl_tcp_ecn namespace aware As per suggestion from Eric Dumazet this patch makes tcp_ecn sysctl namespace aware. The reason behind this patch is to ease the testing of ecn problems on the internet and allows applications to tune their own use of ecn.
