Why I did it
Reverting DHCP counter changes due to unexpected packet drops seen in recv buffer, causing counter counts to be inaccurate in dhcpmon and affecting dhcp6relay performance
Work item tracking
Microsoft ADO (number only): 26918588
How I did it
Reset submodule head and revert related dockerfile changes
How to verify it
Ran mgmt test and stress test
Why I did it
Support DHCP/DHCPv6 per-interface counter, code change in sonic-build image.
Work item tracking
Microsoft ADO (17271822):
How I did it
- Introduce libjsoncpp-dev in dhcpmon and dhcprelay repo
- Show CLI changes after counter format change
How to verify it
- Manually run show command
- dhcpmon, dhcprelay integration tests
Why I did it
Currently the show and clear cli of dhcp_relayis may cause confusion.
How I did it
Add doc for it: [doc] Add docs for dhcp_relay show/clear cli sonic-utilities#2649
Add dhcp_relay config cli and test cases.
show dhcp_relay ipv4 helper
show dhcp_relay ipv6 destination
show dhcp_relay ipv6 counters
sonic-clear dhcp_relay ipv6 counters
How to verify it
Unit test all passed
Why I did it
DHCPv6 relay config entry is not useful while del dhcpv6 relay config.
How I did it
Remove dhcpv6_relay entry if it is empty and not check entry exist while adding dhcpv6 relay
Why I did it
Currently the config cli of dhcpv4 is may cause confusion and config of dhcpv6 is missing.
How I did it
Add dhcp_relay config cli and test cases.
config dhcp_relay ipv4 helper (add | del) <vlan_id> <helper_ip_list>
config dhcp_relay ipv6 destination (add | del) <vlan_id> <destination_ip_list>
Updated docs for it in sonic-utilities: https://github.com/sonic-net/sonic-utilities/pull/2598/files
How to verify it
Build docker-dhcp-relay.gz with and without INCLUDE_DHCP_RELAY, and check target/docker-dhcp-relay.gz.log
Avoid traceback on sonic-clear command
sonic-clear dhcp6relay_counters

- How I did it
Corrected the way to import using importlib
- How to verify it
Tested the sonic-clear command and verified no traceback is seen
#### Why I did it
**Import issue will cause:**
root@sonic:/# sudo sonic-clear arp
failed to import plugin clear.plugins.dhcprelay: No module named 'show_dhcp_relay'
#### How I did it
Fix the import.
#### How to verify it
run sudo sonic-clear arp
#### Why I did it
- Adapt config/show CLI commands to support DHCPv6 relay
- Support multiple dhcp servers assignment in one command
- Fix IP validation
- Adapt UT and add new UT cases
#### How I did it
- Modify config/show dhcp relay files
- Modify config/show UT files
#### How to verify it
This PR has a dependency on PR https://github.com/Azure/sonic-utilities/pull/1717
Build an image with the dependent PR and this PR
Use config/show DHCPv6 relay commands.
- Why I did it
Make DHCP relay docker an extension. DHCP relay now carries dhcp relay commands CLI plugin and has a complete manifest.
It is installed as extension if INCLUDE_DHCP_REALY is set to y.
DEPENDS on #5939
- How I did it
Modify DHCP relay docker makefile and dockerfile. Make changes to sonic_debian_extension.j2 to install sonic packages.
I moved DHCP related CLI tests from sonic-utilities to DHCP relay docker.
This PR introduces a way to write a plugin as part of docker image and run the tests from cli-plugin-tests directory under docker directory.
The test result is available in target/docker-dhcp-relay.gz.log:
