- Why I did it
Need to remove old static configs from sai.profile files.
New implementation: Azure/sonic-swss#1959
New configuration: #9658
- How I did it
Remove SAI_VXLAN_SRCPORT_RANGE_ENABLE=1 lines from files per HWSKU
- How to verify it
When static config is removed following test will fail (src port will be in range 0-255)
py.test vxlan/test_vnet_vxlan.py --inventory "../ansible/inventory, ../ansible/veos" --host-pattern (testbed)-t0 --module-path ../ansible/library/ --testbed (testbed)-t0 --testbed_file ../ansible/testbed.csv --allow_recover --assert plain --log-cli-level info --show-capture=no -ra --showlocals --disable_loganalyzer --skip_sanity --upper_bound_udp_port 65535 --lower_bound_udp_port 64128
Why I did it
Fix typo and missing files in SN3800 and SN4600C's buffer templates
How I did it
ingress_lossless_xoff_size => ingress_lossless_pool_xoff add missing files for SN4600C-D100C12S2
How to verify it
Deploy the fix and verify whether the device can be up.

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.
Depends on Azure/sonic-utilities#1626
Depends on Azure/sonic-swss#1754
QOS tables in config db used ABNF format i.e "[TABLE_NAME|name] to refer fieldvalue to other qos tables.
Example:
Config DB:
"Ethernet92|3": {
"scheduler": "[SCHEDULER|scheduler.1]",
"wred_profile": "[WRED_PROFILE|AZURE_LOSSLESS]"
},
"Ethernet0|0": {
"profile": "[BUFFER_PROFILE|ingress_lossy_profile]"
},
"Ethernet0": {
"dscp_to_tc_map": "[DSCP_TO_TC_MAP|AZURE]",
"pfc_enable": "3,4",
"pfc_to_queue_map": "[MAP_PFC_PRIORITY_TO_QUEUE|AZURE]",
"tc_to_pg_map": "[TC_TO_PRIORITY_GROUP_MAP|AZURE]",
"tc_to_queue_map": "[TC_TO_QUEUE_MAP|AZURE]"
},
This format is not consistent with other DB schema followed in sonic.
And also this reference in DB is not required, This is taken care by YANG "leafref".
Removed this format from all platform files to consistent with other sonic db schema.
Example:
"Ethernet92|3": {
"scheduler": "scheduler.1",
"wred_profile": "AZURE_LOSSLESS"
},

- Why I did it
Removed 2x40G for SN3800. This mode is not supported by hardware.
- How I did it
Removing it from hwsku.json and platform.json
- How to verify it
Load it in the device and check supported modes
