From: Gui Jianfeng Date: Thu, 17 Apr 2008 21:22:18 +0000 (-0700) Subject: SCTP: Initialize partial_bytes_acked to 0, when all of the data is acked. X-Git-Tag: v2.6.26-rc1~1138^2~7 X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8b73a07c8ffaa70683022566080f4df3328ea18d;p=pandora-kernel.git 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.
