Hi,
When I using the ovs-ofctl utility tool to dump flows from a
non-openvswitch switch without --no-names parameter, and I got error
message.

cmd:

~/openvswitch-2.13.1/utilities/ovs-ofctl -O OpenFlow13 dump-flows tcp:
192.168.17.166:6644

msg:
2020-12-31T10:12:22Z|00001|ofp_table|WARN|table features message missing
required property
ovs-ofctl: received bad reply: (***only uses 512 bytes out of 7056***)
00000000  04 50 02 00 00 00 00 00-6e 6f 76 69 5f 74 61 62 |.P......novi_tab|

...

I also attached the pcap file, please tell me if the switch should be fixed
with the reply messages.
Thanks a lot.

best wishes,
