From 67fa034194bf82a3d5ca841759d921297daa63ca Mon Sep 17 00:00:00 2001 From: Jesse Gross Date: Fri, 3 Oct 2014 15:35:30 -0700 Subject: openvswitch: Add support for matching on OAM packets. Some tunnel formats have mechanisms for indicating that packets are OAM frames that should be handled specially (either as high priority or not forwarded beyond an endpoint). This provides support for allowing those types of packets to be matched. Signed-off-by: Jesse Gross Signed-off-by: Andy Zhou Acked-by: Pravin B Shelar Signed-off-by: David S.

Currently, the flow information that is matched for tunnels and the tunnel data passed around with packets is the same. However, as additional information is added this is not necessarily desirable, as in the case of pointers. This adds a new structure for tunnel metadata which currently contains only the existing struct. This change is purely internal to the kernel since the current OVS_KEY_ATTR_IPV4_TUNNEL is simply a compressed version of OVS_KEY_ATTR_TUNNEL that is translated at flow setup.

The Openvswitch implementation is completely agnostic to the options that are in use and can handle newly defined options without further work. It does this by simply matching on a byte array of options and allowing userspace to setup flows on this array.
