From 40187886bc31aee9c5c6f08f46cde4ab618e9736 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Tue, 23 Jun 2009 11:28:05 -0400 Subject: [PATCH] sctp: release cached route when the transport goes down. When the sctp transport is marked down, we can release the cached route and force a new lookup when attempting to use this transport for anything. This way, if a better route or source address is available, we'll try to use it.
