From 891310d53dcf396d6a92987da265a5ffe6c09d71 Mon Sep 17 00:00:00 2001 From: Michele Baldessari Date: Thu, 30 Oct 2014 10:29:15 +0100 Subject: [PATCH] sctp: add transport state in /proc/net/sctp/remaddr It is often quite helpful to be able to know the state of a transport outside of the application itself (for troubleshooting purposes or for monitoring purposes). Add it under /proc/net/sctp/remaddr. Signed-off-by: Michele Baldessari Acked-by: Neil Horman Signed-off-by: David S.
