From ac40e41f4ddec8882d3f7bc8fa98a4fce8796aff Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Wed, 9 May 2007 13:52:35 -0700 Subject: [SCTP]: Do not include ABORT chunk header in the notification. The socket API draft is unclear about whether to include the chunk header or not. Recent discussion on the sctp implementors mailing list clarified that the chunk header shouldn't be included, but the error parameter header still needs to be there.
