The API seems a little suboptimal, in that:
        uint64_t seqno = ovsdb_idl_set_condition(idl, tc, &cond);
        uint64_t seqno2 = ovsdb_idl_set_condition(idl, tc, &cond);
        if (seqno2 == UINT_MAX) {
            ovs_fatal(0, "condition unchanged");
        }
will always abort with "condition unchanged", I think.

Is there a simple solution?
