I am able to reproduce the issue by running the below commands
$make sandbox SANDBOXFLAGS="--ovn"
$ovn/env1/setup.sh
$ovs-ofctl add-flow br-int "table=0, priority=200, in_port=2, action=controller"
$src_mac=000000000002
$request=ffffffffffff${src_mac}080045100110000000008011000000000000ffffffff0044004300FC0000
$ovs-appctl ofproto/trace br-int in_port=2 $request
Before calling set_switch_config(swconn, &config) in ovn/controller/pinctrl.c
at L108
(https://github.com/openvswitch/ovs/blob/master/ovn/controller/pinctrl.c#L108),
If I set
config.flags = 0; ovn-controller is getting the packet-in message from the Open
vSwitch.
Thanks
