Comment 0 for bug 1786746

I have tested a logging feature for firewall_group in stable/rocky [1], and found a bug. Please follow the following testcase to reproduce this bug:

Environment:
- Devstack stable/rocky
- Create a router with port-A that attach to fwg1

Testcase 1
----------
Create 2 log-resources:
 + A: {ACCEPT, fwg1, port-A }
 + B : {DROP, fwg1, port-A}

NFLOGs are added to iptables correctly
Delete log-resource A
=> expect: NFLOGs for ACCEPT disappears
=> Observed: NFLOGs for ACCEPT still remains => Bug

Testcase 2
----------
Create 2 log-resources
+ A: {ALL, fwg1, port-A }
+ B : {ACCEPT, fwg1, port-A}

=> NFLOGs are added to iptables correctly
Delete log-resource A
=> expect: NFLOGs for ACCEPT and DROP disappears
=> Observed: NFLOGs for ACCEPT and DROP still remains => Bug
