Why I did it
Storage backend has all vlan members tagged. If untagged packets are received on those links, they are accounted as RX_DROPS which can lead to false alarms in monitoring tools. Using this acl to hide these drops.
How I did it
Created a acl template which will be loaded during minigraph load for backend. This template will allow tagged vlan packets and dropped untagged

* [sflow + dropmon] added INCLUDE_SFLOW_DROPMON flag, added patches for hsflowd
*Added a capability of monitoring dropped packets for the sFlow daemon in order to improve network - monitoring, diagnostic, and troubleshooting. The drop monitor service allows the sFlow daemon to export another type of sample - dropped packets as Discard samples alongside Counter samples and Packet Flow samples.

* [Mellanox]Check dmi file permission before access (#11309)
Signed-off-by: Sudharsan Dhamal Gopalarathnam sudharsand@nvidia.com
Why I did it
During the system boot up when 'show platform status' or 'show version' command is executed before STATE_DB CHASSIS_INFO table is populated, the show will try to fallback to use the platform API. The DMI file in mellanox platforms require root permission for access. So if the show commands are executed as admin or any other user, the following error log will appear in the syslog
Jun 28 17:21:25.612123 sonic ERR show: Fail to decode DMI /sys/firmware/dmi/entries/2-0/raw due to PermissionError(13, 'Permission denied')
How I did it
Check the file permission before accessing it.
How to verify it
Added UT to verify. Manually verified if the error log is not thrown.

- Why I did it
This is for the eventual support of multiple architectures for the mellanox platform.
- How I did it
Change the location of the binaries in Switch-SDK-drivers so that the path specifies the target architecture in addition to the target distribution that the debians are built for.
This is the most straightforward way to separate binaries built against different architectures and selectively target them for installation in the mellanox SONiC image.
- How to verify it
Build SONiC for mellanox and verify it compiles successfully.

How I did it
For servers loopback definitions in Dpg, if they contain LoopbackIPInterface with tags AttachTo, which has value of format like <server_name>SOC, the address will be regarded as a SoC IP, and sonic-cfggen now will treat the port connected to the server as active-active if the redundancy_type is either Libra or Mixed.
How to verify it

2. Link Up | When toggling many ports of the Spectrum devices while raising 10GbE link up and link maintenance is enabled, the switch may get stuck and may need to be rebooted.
3. Shared buffer | While moving from lossless to lossy while shared headroom was used, reduction of the shared headroom can only be done prior to pool type change and when shared headroom is not utilized.

- Why I did it
New security feature for enforcing strong passwords when login or changing passwords of existing users into the switch.
- How I did it
By using mainly Linux package named pam-cracklib that support the enforcement of user passwords, the daemon named hostcfgd, will support add/modify password policies that enforce and strengthen the user passwords.
- How to verify it
Manually Verification-
1. Enable the feature, using the new sonic-cli command passw-hardening or manually add the password hardening table like shown in HLD by using redis-cli command
2. Change password policies manually like in step 1.
Notes:
password hardening CLI can be found in sonic-utilities repo-
P.R: Add support for Password Hardening sonic-utilities#2121
code config path: config/plugins/sonic-passwh_yang.py
code show path: show/plugins/sonic-passwh_yang.py
3. Create a new user (using adduser command) or modify an existing password by using passwd command in the terminal. And it will now request a strong password instead of default linux policies.
Automatic Verification - Unitest:
This PR contained unitest that cover:
1. test default init values of the feature in PAM files
2. test all the types of classes policies supported by the feature in PAM files
3. test aging policy configuration in PAM files

This PR brings two changes
Add lossy PG profile for PG2 and PG6 on T1 for ports between T1 and T2.
After PR Update qos config to clear queues for bounced back traffic #10176 , the DSCP_TO_TC_MAP and TC_TO_PG_MAP is updated when remapping is enable
DSCP_TO_TC_MAP
Before After Why do this change
"2" : "1" "2" : "2" Only change for leaf router to map DSCP 2 to TC 2 as TC 2 will be used for lossless TC
"6" : "1" "6" : "6" Only change for leaf router to map DSCP 6 to TC 6 as TC 6 will be used for lossless TC
TC_TO_PRIORITY_GROUP_MAP
Before After Why do this change
"2" : "0" "2" : "2" Only change for leaf router to map TC 2 to PG 2 as PG 2 will be used for lossless PG
"6" : "0" "6" : "6" Only change for leaf router to map TC 6 to PG 6 as PG 6 will be used for lossless PG
So, we have two new lossy PGs (2 and 6) for the T2 facing ports on T1, and two new lossless PGs (2 and 6) for the T0 facing port on T1.
However, there is no lossy PG profile for the T2 facing ports on T1. The lossless PGs for ports between T1 and T0 have been handled by buffermgrd .Therefore, We need to add lossy PG profiles for T2 facing ports on T1.
We don't have this issue on T0 because PG 2 and PG 6 are lossless PGs, and there is no lossy traffic mapped to PG 2 and PG 6
Map port level TC7 to PG0
Before the PCBB change, DSCP48 -> TC 6 -> PG 0.
After the PCBB change, DSCP48 -> TC 7 -> PG 7
Actually, we can map TC7 to PG0 to save a lossy PG.
How I did it
Update the qos and buffer template.
How to verify it
Verified by UT.

Why I did it
Support to use symbol links in platform folder to reduce the image size.
The current solution is to copy each lazy installation targets (xxx.deb files) to each of the folders in the platform folder. The size will keep growing when more and more packages added in the platform folder. For cisco-8000 as an example, the size will be up to 2G, while most of them are duplicate packages in the platform folder.
How I did it
Create a new folder in platform/common, all the deb packages are copied to the folder, any other folders where use the packages are the symbol links to the common folder.
Why platform.tar?
We have implemented a patch for it, see #10775, but the problem is the the onie use really old unzip version, cannot support the symbol links.
The current solution is similar to the PR 10775, but make the platform folder into a tar package, which can be supported by onie. During the installation, the package.tar will be extracted to the original folder and removed.
#### 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

|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

Manually test with following steps:
1. Change config and restart sshd
2. Connect a ssh with -vvv option to show debug message
3. Get running ssh by command and stop it:
```
azureuser@liuh-dev-vm-02:~$ ps -auxww | grep vvv
azureus+ 1614153 0.0 0.0 12244 6004 pts/1S+ 15:48 0:00 ssh admin@10.250.0.101 -vvv

azureuser@liuh-dev-vm-02:~$ kill -Stop 1614153
```
4. Check TCP status from server side with ss command:
https://man7.org/linux/man-pages/man8/ss.8.html
```
admin@vlab-01:~$ ss | grep -i ssh
tcp ESTAB 0 010.250.0.101:ssh 10.250.0.1:58150
tcp FIN-WAIT-2 0 010.250.0.101:ssh 10.250.0.1:58164
tcp ESTAB 0 010.250.0.101:ssh 10.250.0.1:57978
```
FIN-WAIT-2 means server already terminate the connection and wait for client response:
https://kb.iu.edu/d/ajmi
. FIN-WAIT-2 <-- <SEQ=300><ACK=101><CTL=ACK> <-- CLOSE-WAIT
5. Check again later will show the session been complete closed:
```
admin@vlab-01:~$ ss | grep -i ssh
