Message-Id: <1236887360-1904-4-git-send-email-vladislav.yasevich@hp.com> Date: Thu, 12 Mar 2009 15:49:19 -0400 From: Vlad Yasevich <vladislav.yasevich@...com> To: davem@...emloft.net Cc: linux-sctp@...r.kernel.org, netdev@...r.kernel.org, Wei Yongjun <yjwei@...fujitsu.com>, Vlad Yasevich <vladislav.yasevich@...com> Subject: [PATCH net-next 3/4] sctp: fix to send FORWARD-TSN chunk only if peer has such capable From: Wei Yongjun <yjwei@...fujitsu.com> 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.
