Aaron Conole c4ab7b56be openvswitch: add trace points ... This makes openvswitch module use the event tracing framework to log the upcall interface and action execution pipeline. When using openvswitch as the packet forwarding engine, some types of debugging are made possible simply by using the ovs-vswitchd's ofproto/trace command. However, such a command has some limitations: 1. When trying to trace packets that go through the CT action, the state of the packet can't be determined, and probably would be potentially wrong. 2. Deducing problem packets can sometimes be difficult as well even if many of the flows are known 3. It's possible to use the openvswitch module even without the ovs-vswitchd (although, not common use). Introduce the event tracing points here to make it possible for working through these problems in kernel space. The style is copied from the mac80211 driver-trace / trace code for consistency - this creates some checkpatch splats, but the official 'guide' for adding tracepoints, as well as the existing examples all add the same splats so it seems acceptable.
