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 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.
Fix to the correct value for all SPC1 devices.
For 10G added 10GB_CX4_XAUI, 10GB_KX4, 10GB_KR, 10GB_SR and 10GB_ER_LR
For 50G added 50GB_SR2
This bitmask represents all the options available for interface type and some were missing.
Note: it was working just fine if you were setting the value from SONiC CLI but not from the default SAI Profile.

**- 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
* Change port index in port_config.ini to 1-based
* Add default port index to port_config.ini, change platform plugins to accept 1-based port index
* fix port index in sfp_event.py
* First part of skipping not used port for qos configuration
* Use active ports only to set QoS parameters for 6100
* Add a test for qos.json.j2
* Add a test for Dell S6100 buffers.json template
* Update submodulre
