#### Why I did it
Create sonic yang model for SNMP
Tables:SNMP, SNMP_COMMUNITY
#### How I did it
Defined yang models based for SNMP based on snmp.yml
#### How to verify it
Added test cases to verify
Why I did it
This PR is to update Yang model for pfc_enable and pfcwd_sw_enable fields to support more than 2 queues, like 2,3,4,6.
Before this change, the regex "[0-7](,[0-7])?" accepts only no more than 2 queues.
How I did it
Update the regex pattern for pfc_enable and pfcwd_sw_enable, from "[0-7](,[0-7])?" to "[0-7](,[0-7])*
How to verify it
The change is verified by UT. The test input is updated to cover the change.

#### Why I did it
Support the following tables which were introduced during dynamic buffer calculation
- LOSSLESS_TRAFFIC_PATTERN
- DEFAULT_LOSSLESS_BUFFER_PARAMETER
#### How I did it
- LOSSLESS_TRAFFIC_PATTERN
|name|type|range|mandatory|description|
|---|---|---|---|---|
|mtu|uint16|64~10240|true|The maximum packet size of a lossless packet|
|small_packet_percentage|uint8|0~100|true|The percentage of small packet|
- DEFAULT_LOSSLESS_BUFFER_PARAMETER
|name|type|range|mandatory|description|
|---|---|---|---|---|
|default_dynamic_th|int8|-8~7|true|The default dynamic_th for all buffer profiles that are dynamically generated for lossless PG|
|over_subscribe_ratio|uint16|-|false|The oversubscribe ratio for shared headroom pool.|
|||||Semantically, the upper bound is the number of physical ports but it can not be represented in the yang module. So we keep the upper bound open. As the type is (signed) integer whose lower bound is 0 by nature, we do not need to specify the range.|
#### How to verify it
Run unit test
- Why I did it
An issue is encountered when a value "False" is written for a feature in "check_up_status" field, which does not pass YANG validation.
- How I did it
We usually use stypes::boolean_type for such fields, even in this YANG model. This custom type, supports "False" value.
- How to verify it
Write "False" in "check_up_status" field and see if YANG validation passes.

* [BGP]Adding configuration knob to allow advertise Loopback ipv6 /128 prefix
By default when IPv6 address is configured with /128 as subnet mask in Loopback0 interface, it will be advertised as prefix with /64 subnet.
To control this behavior a new field 'bgp_adv_lo_prefix_as_128' is introduced in DEVICE_METADATA table which when set to true will advertise prefix with /128 subnet as it is.
- Why I did it
Yang Model about password hardening feature, the sonic CLI of this feature was autogenerated from this Yang model
- How I did it
Create new Yang model in src/sonic-yang-models/yang-models/sonic-passwh.yang.
- How to verify it
There are unitests(yang test) in this P.R covering all the passwords policies with good and bad values cases.
Or is possible manually using the config/show password commands that were autogenerated from this Yang model. (this CLI code added in sonic-utilities)
- Why I did it
YANG schema is missing for sonic-telemetry
- How I did it
Added YANG schema to sonic-yang-models and appropriate unit tests inside of test and test_config
- How to verify it
Build sonic-yang-models python wheels target and verify that unit tests are passing
Why I did it
At present, there is no mechanism in an event driven model to know that the system is up with all the essential sonic services and also, all the docker apps are ready along with port ready status to start the network traffic. With the asynchronous architecture of SONiC, we will not be able to verify if the config has been applied all the way down to the HW. But we can get the closest up status of each app and arrive at the system readiness.
How I did it
A new python based system monitor tool is introduced under system-health framework to monitor all the essential system host services including docker wrapper services on an event based model and declare the system is ready. This framework gives provision for docker apps to notify its closest up status. CLIs are provided to fetch the current system status and also service running status and its app ready status along with failure reason if any.
How to verify it
"show system-health sysready-status" click CLI
Syslogs for system ready

- Why I did it
To add support for 800G speed for port in the yang.
- How I did it
Change limitation from 400G to 800G.
- How to verify it
Set a port speed to 800G and run the yang DB validation. e.g. by using dynamic port breakout.

Why I did it
To support vlan sub intf short naming format, like subport Eth8.100 for parent portEthernet8 with vlan id 100.
How I did it
Add checks to must condition to verify there is a port or portchannel with the index same as the vlan sub intf.
How to verify it
Run the unttests.
#### Why I did it
PR https://github.com/Azure/sonic-utilities/pull/1825 added validation for the input of `config mirror session add`, and only decimal value is accepted.
An issue https://github.com/Azure/sonic-buildimage/issues/10096 was raised to suggest accepting HEX value as well, and the suggestion makes sense to me.
To accept HEX value for GRE type, and keep backward compatibility as well, I updated the YANG model to support both decimal and hexadecimal input for GRE type.
#### How I did it
Update the regex for GRE type.
#### How to verify it
Verified by UT
