What I did:
Added support when TSA is done on Line Card make sure it's completely
isolated from all e-BGP peer devices from this LC or remote LC
Why I did:
Currently when TSA is executed on LC routes are withdrawn from it's connected e-BGP peers only. e-BGP peers on remote LC can/will (via i-BGP) still have route pointing/attracting traffic towards this isolated LC.
How I did:
When TSA is applied on LC all the routes that are advertised via i-BGP are set with community tag of no-export so that when remote LC received these routes it does not send over to it's connected e-BGP peers.
Also once we receive the route with no-export over iBGP match on it and and set the local preference of that route to lower value (80) so that we remove that route from the forwarding database. Below scenario explains why we do this:
- LC1 advertise R1 to LC3
- LC2 advertise R1 to LC3
- On LC3 we have multi-path/ECMP over both LC1 and LC2
- On LC3 R1 received from LC1 is consider best route over R1 over received from LC2 and is send to LC3 e-BGP peers
- Now we do TSA on LC2
- LC3 will receive R1 from LC2 with community no-export and from LC1 same as earlier (no change)
- LC3 will still get traffic for R1 since it is still advertised to e-BGP peers (since R1 from LC1 is best route)
- LC3 will forward to both LC1 and LC2 (ecmp) and this causes issue as LC2 is in TSA mode and should not receive traffic
To fix above scenario we change the preference to lower value of R1 received from LC2 so that it is removed from Multi-path/ECMP group.

#### Why I did it
SNMP query over IPv6 does not work due to issue in net-snmp where IPv6 query does not work on multi-nic environment.
To get around this, if snmpd listens on specific ipv4 or ipv6 address, then the issue is not seen.
We plan to configure Management IP and Loopback IP configured in minigraph.xml as SNMP_AGENT_ADDRESS in config_db., based on changes discussed in https://github.com/sonic-net/SONiC/pull/1457.
##### Work item tracking
- Microsoft ADO **(number only)**:26091228
#### How I did it
Modify minigraph parser to update SNMP_AGENT_ADDRESS_CONFIG with management and Loopback0 IP addresses.
Modify snmpd.conf.j2 to use SNMP_AGENT_ADDRESS_CONFIG table if it is present in config_db, if not listen on any IP.
Main change:
1. if minigraph.xml is used to configure the device, then snmpd will listen on mgmt and loopback IP addresses,
2. if config_db is used to configure the device, snmpd will listen IP present in SNMP_AGENT_ADDRESS_CONFIG if that table is present, if table is not present snmpd will listen on any IP.
#### How to verify it
config_db.json created from minigraph.xml for single asic VS image with mgmt and Loopback IP addresses.
```
"SNMP_AGENT_ADDRESS_CONFIG": {
"10.1.0.32|161|": {},
"10.250.0.101|161|": {},
"FC00:1::32|161|": {},
"fec0::ffff:afa:1|161|": {}
},
.....
snmpd listening on the above IP addresses:
admin@vlab-01:~$ sudo netstat -tulnp | grep 161
tcp 0 0 127.0.0.1:3161 0.0.0.0:* LISTEN 71522/snmpd

This commit adds support for pensando asic called ELBA. ELBA is used in pci based cards and in smartswitches.
#### Why I did it
This commit introduces pensando platform which is based on ELBA ASIC.
##### Work item tracking
- Microsoft ADO **(number only)**:
#### How I did it
Created platform/pensando folder and created makefiles specific to pensando.
This mainly creates pensando docker (which OEM's need to download before building an image) which has all the userspace to initialize and use the DPU (ELBA ASIC).
Output of the build process creates two images which can be used from ONIE and goldfw.
Recommendation is use to use ONIE.
#### How to verify it
Load the SONiC image via ONIE or goldfw and make sure the interfaces are UP.
##### Description for the changelog
Add pensando platform support.

Remove Python3 venv in Python3-only sonic-mgmt-docker
How to verify it
There is no impact to sonic-mgmt-docker:latest tag.
Build sonic-mgmt-docker with LEGACY_SONIC_MGMT_DOCKER=y, see python3 venv is there.
Build sonic-mgmt-docker with LEGACY_SONIC_MGMT_DOCKER=n, see python3 venv is NOT included.
Modify j2 template files in docker-dhcp-relay. Add dhcprelayd to group dhcp-relay instead of isc-dhcp-relay-VlanXXX, which would make dhcprelayd to become critical process.
In dhcprelayd, subscribe FEATURE table to check whether dhcp_server feature is enabled.
2.1 If dhcp_server feature is disabled, means we need original dhcp_relay functionality, dhcprelayd would do nothing. Because dhcrelay/dhcpmon configuration is generated in supervisord configuration, they will automatically run.
2.2 If dhcp_server feature is enabled, dhcprelayd will stop dhcpmon/dhcrelay processes started by supervisord and subscribe dhcp_server related tables in config_db to start dhcpmon/dhcrelay processes.
2.3 While dhcprelayd running, it will regularly check feature status (by default per 5s) and would encounter below 4 state change about dhcp_server feature:
A) disabled -> enabled
In this scenario, dhcprelayd will subscribe dhcp_server related tables and stop dhcpmon/dhcrelay processes started by supervisord and start new pair of dhcpmon/dhcrelay processes. After this, dhcpmon/dhcrelay processes are totally managed by dhcprelayd.
B) enabled -> enabled
In this scenaro, dhcprelayd will monitor db changes in dhcp_server related tables to determine whether to restart dhcpmon/dhrelay processes.
C) enabled -> disabled
In this scenario, dhcprelayd would unsubscribe dhcp_server related tables and kill dhcpmon/dhcrelay processes started by itself. And then dhcprelayd will start dhcpmon/dhcrelay processes via supervisorctl.
D) disabled -> disabled
dhcprelayd will check whether dhcrelay processes running status consistent with supervisord configuration file. If they are not consistent, dhcprelayd will kill itself, then dhcp_relay container will stop because dhcprelayd is critical process.
This is change taken as part of the HLD: sonic-net/SONiC#1470 and this is a follow up on the PR #16827 where in the docker-dhcp we pick the value of primary gateway of the interface from the VLAN_Interface table which has "secondary" flag set in the config_db
Microsoft ADO (number only): 16784946
How did I do it
- Changes in the j2 file to add a new "-pg" parameter in the dhcpv4-relay.agents.j2, the ip would be retrieved from the config db's vlan_interface table such that the interface which are picked will have secondary field set.
- Changes in isc-dhcp to re-order the addresses of the discovered interface and which has the ip which has the passed parameter.

What I did:
In Chassis TSA mode Loopback0 Ip's of each LC's should be advertise through e-BGP peers of each remote LC's
How I did:
- Route-map policy to Advertise own/self Loopback IP to other internal iBGP peers with a community internal_community as define in constants.yml
- Route-map policy to match on above internal_community when route is received from internal iBGP peers and set a internal tag as define in constants.yml and also delete the internal_community so we don't send to any of e-BGP peers
- In TSA new route-map match on above internal tag and permit the route (Loopback0 IP's of remote LC's) and set the community to traffic_shift_community.
- In TSB delete the above new route-map.

Fix#13561
The existing saidump use https://github.com/sonic-net/sonic-swss-common/blob/master/common/table_dump.lua script which loops the ASIC_DB more than 5 seconds and blocks other processes access.
This solution uses the Redis SAVE command to save the snapshot of DB each time and recover later, instead of looping through each entry in the table.

How did I do it?
To use the Redis-db SAVE option to save the snapshot of DB each time and recover later, instead of looping through each entry in the table and saving it.
1. Updated dockers/docker-base-bullseye/Dockerfile.j2, install Python library rdbtools into the all the docker-base-bullseye containers.
2. Updated sonic-buildimage/src/sonic-sairedis/saidump/saidump.cpp, add a new option -r, which updates the rdbtools's output-JSON files' format.
3. To add a new script file: syncd/scripts/saidump.sh into the sairedis repo. This shell script does the following steps:
For each ASIC, such as ASIC0,
3.1. Config Redis consistency directory.
redis-cli -h $hostname -p $port CONFIG SET dir $redis_dir > /dev/null
3.2. Save the Redis data.
redis-cli -h $hostname -p $port SAVE > /dev/null
3.3. Run rdb command to convert the dump files into JSON files
rdb --command json $redis_dir/dump.rdb | tee $redis_dir/dump.json > /dev/null
3.4. Run saidump -r to update the JSON files' format as same as the saidump before.
Then we can get the saidump's result in standard output."
saidump -r $redis_dir/dump.json -m 100
3.5. Clear the temporary files.
rm -f $redis_dir/dump.rdb
rm -f $redis_dir/dump.json
4. Update sonic-buildimage/src/sonic-utilities/scripts/generate_dump. To check the asic db size and if it is larger than ROUTE_TAB_LIMIT_DIRECT_ITERATION (with default value 24000) entries, then do with REDIS SAVE, otherwise, to do with old method: looping through each entry of Redis DB.
How to verify it
On T2 setup with more than 96K routes, execute CLI command -- generate_dump
No error should be shown
Download the generate_dump result and verify the saidump file after unpacking it.
