From a175a723301a8a4a9fedf9ce5b8ca586e7a97b40 Mon Sep 17 00:00:00 2001 From: Joe Stringer Date: Thu, 22 Aug 2013 12:30:48 -0700 Subject: openvswitch: Add SCTP support This patch adds support for rewriting SCTP src,dst ports similar to the functionality already available for TCP/UDP. Rewriting SCTP ports is expensive due to double-recalculation of the SCTP checksums; this is performed to ensure that packets traversing OVS with invalid checksums will continue to the destination with any checksum corruption intact.
