Got it. Thank you.
OFPXMT_OFB_METADATA would also work for my goal. But tests show that metadata
is not sent as well.
On switch:
$ sudo ovs-ofctl -O OpenFlow13 dump-flows s2
OFPST_FLOW reply (OF1.3) (xid=0x2):
cookie=0x0, duration=12.958s, table=0, n_packets=0, n_bytes=0,
priority=1,udp,tp_dst=30012
actions=CONTROLLER:65535,write_metadata:0x1/0xffffffff
On controller:
PACKET IN ARRIVED
OFPPacketIn received: buffer_id=ffffffff total_len=220 reason=ACTION table_id=0
cookie=0 match=OFPMatch(oxm_fields={'in_port': 1})
