modify the VLAN Tag and network_name of a subnet in OVN,ovs trace and communication failure.

[zhaiyj]

I want to modify the VLAN Tag and network_name of a subnet in OVN, and I also hope to change the patch port connections from br-int and br-public-net to br-int and br-trunk-net. However, after making these changes, the output of ovs-vsctl show reflect the expected configuration, and there are still issues when running ovs-trace, indicating that the modification was not successful. Here's the current configuration situation.

ovs trace flow detail:
