- Why I did it
Added the fwtrace config files in order to be able to call the mlxstrace utility during the show techsupport dump.

Microsoft ADO (number only):
- How I did it
Added fwtrace config files. Added path to these files to sai.profile for each mlnx device.
- How to verify it
Execute the show techsupport command and check if mlxstrace output is in system dump.

- Why I did it
The capability files were incorrect in comparison to the marketing spec of the SN4410 platform.
- How I did it
Aligned the capability files according to the marketing spec.
- How to verify it
Basic manual sanity checks:
1. Check if critical docker containers were UP
2. Check if interfaces were created and were UP
3. Check if interfaces created in the syncd docker container by executing – sx_api_ports_dump.py script
4. Check the logs from the start of the switch – everything was OK
5. Verified the port breakout

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
Dependency: It depends on Azure/sonic-swss#1910 and submodule advancing PR once the former merged.
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
Add NVIDIA Copyright header to "mellanox" files
- How I did it
Add NVIDIA Copyright header as a comment for Mellanox files
- How to verify it
Sanity tests and PR checkers.
- Why I did it
The MSN4410 platform was missing 2x100G and 4x50G supported breakout modes in platform.json
- How I did it
Added the aforementioned breakout modes to platform.json
- How to verify it
Run show interface breakout on a MSN4410 and verify that 2x100G and 4x50G are listed in the supported breakout modes for ports 1-24.
- 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
Add missed files for dynamic buffer calculation for ACS-MSN3420 and ACS-MSN4410
- How I did it
asic_table.j2: Add mapping from platform to ASIC
Add buffer_dynamic.json.j2 for ACS-MSN4410.
- How to verify it
Check whether the dynamic buffer calculation daemon starts successfully.

- Why I did it
platform.json and hwsku.json files are required for a feature called Dynamic Port Breakout
- How I did it
