OK, I figured out the problem. Property 10, OFPTFPT_WILDCARDS, is missing. OF1.3 section 7.3.5.5.2 says that it's mandatory: "If a specific property does not have any capability (for example no Set-Field support), a property with an empty list must be included in the property list." I think that OVS is correctly rejecting this set of table features.
