From 76595024ffab3599bd28ea014f6c23c1a8c8dd2c Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Thu, 12 Mar 2009 09:49:19 +0000 Subject: [PATCH] sctp: fix to send FORWARD-TSN chunk only if peer has such capable RFC3758 Section 3.3.1. Sending Forward-TSN-Supported param in INIT Note that if the endpoint chooses NOT to include the parameter, then at no time during the life of the association can it send or process a FORWARD TSN. If peer does not support PR-SCTP capable, don't send FORWARD-TSN chunk to peer. Signed-off-by: Wei Yongjun Signed-off-by: Vlad Yasevich Signed-off-by: David S.
