Cherry pick of #10072
- Why I did it
Removing DPB breakout modes that require adjacent ports to be disabled as that is not supported by the current DPB infrastructure.
Correspondingly had to remove the hwsku.json file from any SKUs which utilized these removed modes such that the system will fall back to ports_config.ini and DPB will not be supported for those SKUs.
- How I did it
Modified the platform.json files of Mellanox devices.
- How to verify it
Execute show int break [Ethernet] on the affected platforms and ensure there are no modes present that would require an adjacent port to be disabled to function.
This is to backport community PR #8768 to 202106 branch
Why I did it
Support zero buffer profiles
Add buffer profiles and pool definition for zero buffer profiles
Support applying zero profiles on INACTIVE PORTS
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
SN4600 A0 platform was EOL, so there is no need to support it, sensor conf can be removed and we don't need to maintain 2 sensor conf files, only A1 platform is needed.
- How I did it
Remove get_sensors_conf_path which intends to load correct sensor conf for different(A0/A1) platforms.
Remove the sensor conf for A0 platform, rename previous sensor.conf.a1 to sensor.conf
- How to verify it
Run sensor test on the SN4600 platform.
*Edited platform.json for 4600 & 4600C
*Edited hwsku.json and port_config.ini files for all the SKU's present under these platforms

- Why I did it
To create SDK dump on Mellanox devices when SDK event has occurred.
- How I did it
Set the SKUs keys needed to initialize the feature in SAI.
- How to verify it
Simulate SDK event and check that dump is created in the expected path.
#### Why I did it
Current platform.json lacks some peripheral device related facts, like chassis/fan/pasu/drawer/thermal/components names, numbers, etc.
#### How I did it
Add platform device facts to the platform.json file

- Why I did it
Fix the build and fix the SN4600 DPB support
- How I did it
Fix port configuration file for SN4600 based on recent changes
- How to verify it
System bringup is completed, all interfaces are up.
Platform tests suits all is passing.
- Why I did it
To add support for the dynamic breakout on Mellanox platform x86_64-mlnx_msn4600
- How I did it
Add the relevant files describing Mellanox platform x86_64-mlnx_msn4600 breakout modes to a new device folder.
- How to verify it
System bringup is completed, all interfaces are up.
Platform tests suits all is passing.

Add support for new 64x200G SN4600 systems
- How I did it
Add all relevant files (w/o platform.json and hwsku.json as they will come later) with default SKU.
- How to verify it
Install image on switch, verify all ports are up and configured properly, run full platform SONiC tests.
