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 platform_asic file to each platform folder in sonic-device-data package. The file content will be used as the ground truth of mapping from PLATFORM_STRING to switch ASIC family.
One use case of the mapping is to prevent installing a wrong image, which targets for other ASIC platforms. For example, currently we have several ONIE images naming as sonic-*.bin, it's easy to mistakenly install the wrong image. With this mapping built into image, we could fetch the ONIE platform string, and figure out which ASIC it is using, and check we are installing the correct image.
After this PR merged, each platform vendor has to add one mandatory text file `device/PLATFORM_VENDOR/PLATFORM_STRING/platform_asic`, with the content of the platform's switch ASIC family.
I will update https://github.com/Azure/SONiC/wiki/Porting-Guide after this PR is merged.
You can get a list of the ASIC platforms by `ls -b platform | cat`. Currently the options are
```
barefoot
broadcom
cavium
centec
centec-arm64
generic
innovium
marvell
marvell-arm64
marvell-armhf
mellanox
nephos

Also support

#### How I did it
#### How to verify it
Test one image on DUT. And check the folders under `/usr/share/sonic/device`
- 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
The label for PSU related sensors on the Spectrum-2 platform is not aligned with the physical location of the PSU.
#### How I did it
Update the label in the sensor conf file for those relevant platforms

#### 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

To fix [DPB| wrong aliases for interfaces](https://github.com/Azure/sonic-buildimage/issues/6024) issue, implimented flexible alias support [design doc](https://github.com/Azure/SONiC/pull/749)
> [[dpb|config] Fix the validation logic of breakout mode](https://github.com/Azure/sonic-utilities/pull/1440) depends on this
#### How I did it
1. Removed `"alias_at_lanes"` from port-configuration file(i.e. platfrom.json)
2. Added dictionary to "breakout_modes" values. This defines the breakout modes available on the platform for this parent port, and it maps to the alias list. The alias list presents the alias names for individual ports in order under this breakout mode.
```
{
"interfaces": {
"Ethernet0": {
"index": "1,1,1,1",
"lanes": "0,1,2,3",
"breakout_modes": {
"1x100G[40G]": ["Eth1"],
"2x50G": ["Eth1/1", "Eth1/2"],
"4x25G[10G]": ["Eth1/1", "Eth1/2", "Eth1/3", "Eth1/4"],
"2x25G(2)+1x50G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"],
"1x50G(2)+2x25G(2)": ["Eth1/1", "Eth1/2", "Eth1/3"]
}
}
}
```
#### How to verify it
`config interface breakout`

**- 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
This PR has a dependency on community change to move PCIe config files from $PLATFORM/plugin folder to $PLATFORM/ folder
