- Why I did it
Optimize thermal control policies to simplify the logic and add more protection code in policies to make sure it works even if kernel algorithm does not work.
- How I did it
Reduce unused thermal policies
Add timely ASIC temperature check in thermal policy to make sure ASIC temperature and fan speed is coordinated
Minimum allowed fan speed now is calculated by max of the expected fan speed among all policies
Move some logic from fan.py to thermal.py to make it more readable
- How to verify it
1. Manual test
2. Regression
Taken from https://github.com/Azure/sonic-buildimage/pull/9539
#### Why I did it
To fix an issue that hw-mgmt patches were not applied. One patch was already in upstream hw-mgmt package thus applying it again caused an error and no other patches were applied. Also, I did it to improve the Makefile, so that the make will fail in case patches fail to apply.
#### How I did it
Removed obsolete patch, made applying patches a hard failure in the build.
#### How to verify it
Run the make and verify patches are applied.
- Why I did it
Bug fix:
bad_param request due to missing parser rest command while running mlxlink
- How I did it
Advance to MFT tool version to 4.17.2-12.
- How to verify it
Manually tested on all mellanox platforms.
- Why I did it
Update hw-mgmt to a new version to pick up support for the SN4600C A1 system.
- How I did it
Update the pointer of the hw-mgmt submodule
Update the hw-mgmt version number
Remove the staled code patch to hw-mgmt userspace code.
- How to verify it
Run platform regression on Mellanox platforms.

- Why I did it
To have an ability to use PRM sniffer.
- How I did it
Enabled the option in configure flags.
- How to verify it
Built and ran on switch. Enabled the feature in runtime and checked the sniffer recording.

Backport https://github.com/Azure/sonic-buildimage/pull/9259 to 202012
#### Why I did it
Nvidia platform API does not support set LED to orange.
#### How I did it
Allow user to set LED to orange
#### How to verify it
Manual test
Why I did it
Arista did not update db with eeprom info. Previous PR had issues that were reverted.
How I did it
Had Arista eeprom class inherit the class that has method to update db. Updated platform API methods for Arista 202012.
How to verify it
In redis-cli the keys and values can be seen. Can use sonic-mgmt testing to verify behavior, and see the chassis platform API methods have not regressed.
- Why I did it
Support zero buffer profiles
1. Add buffer profiles and pool definition for zero buffer profiles
2. Support applying zero profiles on INACTIVE PORTS
3. Enable dynamic buffer manager to load zero pools and profiles from a JSON file
- How I did it
Add buffer profiles and pool definition for zero buffer profiles
If the buffer model is static:
* Apply normal buffer profiles to admin-up ports
* Apply zero buffer profiles to admin-down ports
If the buffer model is dynamic:
* Apply normal buffer profiles to all ports
* buffer manager will take care when a port is shut down
Update buffers_config.j2 to support INACTIVE PORTS by extending the existing macros to generate the various buffer objects, including PGs, queues, ingress/egress profile lists
Originally, all the macros to generate the above buffer objects took active ports only as an argument.
Now that buffer items need to be generated on inactive ports as well, an extra argument representing the inactive ports need to be added.
To be backward compatible, a new series of macros are introduced to take both active and inactive ports as arguments
The original version (with active ports only) will be checked first. If it is not defined, then the extended version will be called.
Only vendors who support zero profiles need to change their buffer templates
Enable buffer manager to load zero pools and profiles from a JSON file:
The JSON file is provided on a per-platform basis
It is copied from platform/<vendor> folder to /usr/share/sonic/temlates folder in compiling time and rendered when the swss container is being created.
To make code clean and reduce redundant code, extract common macros from buffer_defaults_t{0,1}.j2 of all SKUs to two common files:
One in Mellanox-SN2700-D48C8 for single ingress pool mode
The other in ACS-MSN2700 for double ingress pool mode
Those files of all other SKUs will be symbol link to the above files
Update sonic-cfggen test accordingly:
* Adjust example output file of JSON template for unit test
* Add unit test in for Mellanox's new buffer templates.
- How to verify it
Regression test.
Unit test in sonic-cfggen
Run regression test and manually test.

- Why I did it
To include latest fixes.
1. On CMIS modules, after low power configuration, the firmware waited for the module state to be ModuleReady instead of ModuleLowPower causing delays.
2. When connecting Spectrum devices with optical transceivers that support RXLOS, remote side port down might cause the switch firmware to get stuck and cause unexpected switch behavior.
3. On rare occasions, when working with port rates of 1GbE or 10GbE and congestion occurs, packets may get stuck in the chip and may cause switch to hang.
4. When ECMP has high amount of next-hops based on VLAN interfaces, in some rare cases, packets will get a wrong VLAN tag and will be dropped.
5. Using SN4600C with copper or optics loopback cables in NRZ speeds, link may raise in long link up times ( up to 70 seconds).
6. When connecting SN4600C to SN4600C after Fastboot in 50GbE No_FEC mode with a copper cable, the link up time may take ~20 seconds.

This is to update the common sonic-buildimage infra for reclaiming buffer.
- How I did it
Render zero_profiles.j2 to zero_profiles.json for vendors that support reclaiming buffer
The zero profiles will be referenced in PR [Reclaim buffer] Reclaim unused buffers by applying zero buffer profiles #8768 on Mellanox platforms and there will be test cases to verify the behavior there.
Rendering is done here for passing azure pipeline.

- Why I did it
When PSU is powered off, the PSU is still on the switch and the air flow is still the same. In this case, it is not necessary to set FAN speed to 100%.
- How I did it
When PSU is powered of, don't treat it as absent.
- How to verify it

Why I did it
The previous PR #8914 was reverted due to crashing the 202012 syseepromd.
How I did it
Tested the 202012 image with change and fixed the disparity between master and 202012.
How to verify it
Run the built image on the dut and syseepromd will not crash, and in redis-cli can fetch the eeprom information.
Why I did it
Sujin noticed that Arista eeprom platform API cannot update the redis database. Although Arista and Guohan believe that database update logic should be part of the daemon, it is easy enough to implement the fix for Arista for now.
How I did it
Made Arista eeprom platform API inherit from TlvInfoDecoder, then write Arista's own visit_eeprom method.

Why I did it
Vaibhav Dahiya notified me that invalid fan speed policy was expecting an error raised in sonic-mgmt testing, but it was not raised.
This change will fix test_platform_info.py::test_thermal_control_load_invalid_value_json
How I did it
Add in the suggested code chunk to Arista platform submodule to raise ValueError when an invalid fan speed is set in thermal policy.
How to verify it
Vaibhav Dahiya has verified it through sonic-mgmt testing.

- Why I did it
Change thermal recover threshold from temp_trip_norm to temp_trip_high, so that thermal algorithm would set fan speed to minimum allowed earlier and save power.

Why I did it
To monitor the SSD health condition in DellEMC S6100 platform post upgrade.
A daemon is introduced to monitor the SSD every one hour.
To check for SSD status at boot time and at the time of cold-reboot.
All these changes are supported only for newer SSD firmware.
Porting changes from 201911 branch
Added a platform_reboot_pre_check script to prevent cold-reboot based on SSD status.
Depends on Azure/sonic-utilities#1788
