From 0eca8fee0ce3fa0962ac98ab30c10995754a3195 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Fri, 11 Jan 2008 10:12:56 -0500 Subject: [SCTP]: Do not increase rwnd when reading partial notification. When a user reads a partial notification message, do not update rwnd since notifications must not be counted towards receive window.
