I have found the root cause.

It works after I run the following command

sudo ovs-ofctl -Oopenflow13 --strict del-flows br-int "table=94, n_packets=12485, n_bytes=1063359, idle_age=0, priority=12,reg6=0x3,dl_dst=fa:16:3e:34:9e:64"

This rule is introduced by this patch - https://review.opendev.org/c/openstack/neutron/+/704506/1/neutron/agent/linux/openvswitch_firewall/firewall.py#1096

So it's a regression for lp bug https://bugs.launchpad.net/neutron/+bug/1732067
