Backport #14372 to 202012
Why I did it
For better accounting purposes, updating the ingress lossy traffic profile to use static threshold. This change is only intended for Th devices using RDMA-CENTRIC profiles
How I did it
Update the buffer templates for Th devices in RDMA-CENTRIC folder to use the correct threshold
Signed-off-by: Neetha John <nejo@microsoft.com>
Why I did it
Update dynamic threshold to -1 to get optimal performance for RDMA traffic
How I did it
Modified pg_profile_lookup.ini to reflect the correct value

Why I did it
ECN parameters need to be updated for storage backend
How I did it
Included the check for storage backend devices to update qos configs
How to verify it
Verified that the new ecn settings are applied on storage backend device.
Verified that the old ecn settings are applied for storage frontend, non storage frontend/backend devices

This is to backport #12626
Why I did it
There is a need to have separate profiles on compute and storage and this infra update will help achieve that
How I did it
Moved buffer pool/profile and qos definitions on TD2 to a common folder and all TD2 hwsku's will reference that folder
Why I did it
This PR is to update TC_TO_QUEUE_MAP|AZURE for SKU Arista-7050CX3-32S-D48C8 and Arista-7260CX3 T0.
The change is only to align the TC_TO_QUEUE_MAP for regular traffic and bounced traffic. It has no impact on business because we have no traffic being mapped to TC2 or TC6.
How I did it
Update TC_TO_QUEUE_MAP|AZURE , and test cases as well.
How to verify it
Verified by running test case test_j2files.py
/sonic/src/sonic-config-engine$ python3 setup.py test -s tests/test_j2files.py
running test

This PR is to backport #11569 into 202012 branch.
This PR is to apply different DSCP_TO_TC_MAP to downlink and uplink ports on T1 in dualtor deployment.
For T1 downlink ports (To T0)
The DSCP_TO_TC_MAP is not changed. DSCP2 and DSCP6 are mapped to TC2 and TC6 respectively.
For T1 uplink ports (To T1)
A new DSCP_TO_TC_MAP|AZURE_UPLINK is defined and applied. DSCP2 and DSCP6 are mapped to TC1 to avoid mixing up lossy and lossless traffic from T2.
The extra lossy PG2 and PG6 added in PR #11157 is reverted as well because no traffic from T2 is mapped to PG2 or PG6 now.
How I did it
Define a new map DSCP_TO_TC_MAP|AZURE_UPLINK for 7260 T1.
How to verify it
Verified by test case in test_j2files.py.
Signed-off-by: Neetha John <nejo@microsoft.com>
Why I did it
Improve throughput and latency for 7260 deployments
How I did it
Update the dynamic threshold to 0 and ECN settings as 2mb/10mb/5%
How to verify it
Updated unit tests to use the modified values for 7260 ecn settings.
