From fd4e7b50455330403ed5b1060055f9d411ecdc57 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Mon, 31 Mar 2008 19:43:18 -0700 Subject: [PATCH] [IPV4][NETNS]: Display per-net info in sockstat file. Besides, now we can see per-net fragments statistics in the same file, since this stats is already per-net. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
