- Why I did it
Added missing functionality for dynamic buffer calculation in Spectrum-4.
- How I did it
Added a section of code in asic_table.j2 for Spectrum-4, and added the simx version of SN5600 to the supported list.
- How to verify it
Manually: buffershow -l should show all ingress/egress lossy/lossless pools, and all fields of profiles should show values.
Automatically: https://github.com/Azure/sonic-mgmt/blob/master/tests/qos/test_buffer.py

- Why I did it
Rename platform x86_64-mlnx_msn4800 to x86_64-nvidia_msn4800
- How I did it
Rename platform folder as well as all code that reference the platform name
- How to verify it
Manual test
- Why I did it
Add new Spectrum-4 system support SN5600 on top of Nvidia ASIC simulator.
- How I did it
Add all relevant system and simulator SKU.
Updated syseeprom.hex and related directories to reflect Nvidia SN5600 brand name.
- How to verify it
Tested init flow, basic show commands, up interfaces, traffic test.

- Why I did it
Add support for SN2201 platform
- How I did it
Add required content for SN2201 platform
Note: still missing kernel driver support for this system. Once all is upstream will be updated as well.
- How to verify it
Install and basic sanity tests including traffic.

- Why I did it
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.
**- Why I did it**
To support dynamic buffer calculation.
This PR also depends on the following PRs for sub modules
- [sonic-swss: [buffermgr/bufferorch] Support dynamic buffer calculation #1338](https://github.com/Azure/sonic-swss/pull/1338)
- [sonic-swss-common: Dynamic buffer calculation #361](https://github.com/Azure/sonic-swss-common/pull/361)
- [sonic-utilities: Support dynamic buffer calculation #973](https://github.com/Azure/sonic-utilities/pull/973)
**- How I did it**
1. Introduce field `buffer_model` in `DEVICE_METADATA|localhost` to represent which buffer model is running in the system currently:
- `dynamic` for the dynamic buffer calculation model
- `traditional` for the traditional model in which the `pg_profile_lookup.ini` is used
2. Add the tables required for the feature:
- ASIC_TABLE in platform/\<vendor\>/asic_table.j2
- PERIPHERAL_TABLE in platform/\<vendor\>/peripheral_table.j2
- PORT_PERIPHERAL_TABLE on a per-platform basis in device/\<vendor\>/\<platform\>/port_peripheral_config.j2 for each platform with gearbox installed.
- DEFAULT_LOSSLESS_BUFFER_PARAMETER and LOSSLESS_TRAFFIC_PATTERN in files/build_templates/buffers_config.j2
- Add lossless PGs (3-4) for each port in files/build_templates/buffers_config.j2
3. Copy the newly introduced j2 files into the image and rendering them when the system starts
4. Update the CLI options for buffermgrd so that it can start with dynamic mode
5. Fetches the ASIC vendor name in orchagent:
- fetch the vendor name when creates the docker and pass it as a docker environment variable
- `buffermgrd` can use this passed-in variable
6. Clear buffer related tables from STATE_DB when swss docker starts
7. Update the src/sonic-config-engine/tests/sample_output/buffers-dell6100.json according to the buffer_config.j2
8. Remove buffer pool sizes for ingress pools and egress_lossy_pool
Update the buffer settings for dynamic buffer calculation
