This adds a couple of comments of the form
/* OUTPUT to a real port can not refer to versionable lookups (flow tables,
* groups), so we do not need to worry about the version to use here. */
but I'm not sure that I believe it. In particular,
compose_table_xlate(), which has this comment, outputs to OFPP_TABLE,
which isn't a real port at all but instead does a full flow table
traversal.
This line in packet_execute() needs an extra space:
execute.actions =opo->odp_actions.data;
I'm surprised to see ofproto.c including ofproto-dpif-xlate.h. That
seems like a layer violation.
