From 8b73a07c8ffaa70683022566080f4df3328ea18d Mon Sep 17 00:00:00 2001 From: Gui Jianfeng Date: Thu, 17 Apr 2008 14:22:18 -0700 Subject: SCTP: Initialize partial_bytes_acked to 0, when all of the data is acked. According to RFC4960 7.2.2, When all of the data transmitted by the sender has been acknowledged by the recerver, partial_bytes_acked is initialized to 0. This patch conforms to rfc requirement. Without this fix, cwnd might be error incremented. Signed-off-by: Gui Jianfeng Acked-by: Vlad Yasevich Signed-off-by: David S.
