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
Arista 7060 platform has a rare and unreproduceable PCIe timeout that could possibly be solved with increasing the switch PCIe timeout value. To do this we'll call a script for this platform to increase the PCIe timeout on boot-up.
No issues would be expected from the setpci command. From the PCIe spec:
"Software is permitted to change the value in this field at any
time. For Requests already pending when the Completion
Timeout Value is changed, hardware is permitted to use either
the new or the old value for the outstanding Requests, and is
permitted to base the start time for each Request either on when
this value was changed or on when each request was issued. "
How I did it
Add "platform-init" support in swss docker similar to how "hwsku-init" is called, only this would be for any device belonging to a platform. Then the script would reside in device data folder.
Additionally, add pciutils dependency to docker-orchagent so it can run the setpci commands.
How to verify it
On bootup of an Arista 7060, can execute:
lspci -vv -s 01:00.0 | grep -i "devctl2"
In order to check that the timeout has changed.
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

Why I did it
After PFC interop testing between 8102 and 7050cx3, data packet losses were observed on the Rx ports of the 7050cx3 (inflow from 8102) during testing. This was primarily due to the slower response times to react to PFC pause packets for the 8102, when receiving such frames from neighboring devices. To solve for the packet drops, the 7050cx3 pg headroom size has to be increased to 160kB.
How I did it
Modified the xoff threshold value to 160kB in the pg_profile file to allow for the buffer manager to read that value when building the image, and configuring the device
How to verify it
run "mmuconfig -l" once image is built

Why I did it
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.

Why I did it
As part of PCBB changes, we need to enable 2 extra lossless queues. The changes in this PR are done to adjust only the reserved sizes on Th2 for the additional 2 lossless queues
Calculations are done based on 40 downlinks for T1 and 16 uplinks for dual ToR
How to verify it
Verified that the rendering works fine on Th2 dut
Unit tests have been updated to reflect the modified buffer sizes when pcbb is enabled. There are existing testcases that will test the original buffer sizes when pcbb is disabled. With these changes, was able to build sonic-config-engine wheel successfully

This was an ask by Microsoft to provide:
7260 config.bcm file for hardware sku Arista-7260CX3-D92C16 (Named Arista-7260CX3-D96C16).
There are 16 100G uplinks:
Ethernet13-20/1
Ethernet45-52/1
All other ports are breakout to 2 50G ports.
The original ask was for 201811. This is the requested PR for 202012.
How I did it
Copied existing Arista-7260CX3-D108C8 HWSKU and altered the bcm config, port_config.ini, and buffers config files.

This is to address an issue where it was observed that SAI operations sometime make take a very long to time complete (over 45ms). It was determined that the ALPM distributed thread was causing this issue.
The fix is to disable this debug thread that has no functional purpose.
Preliminary tests looks fine. BGP neighbors were all up with proper routes programmed
interfaces are all up
Manually ran the fib test cases on 7050CX3 (TD3), TD2, TH, TH2, and TH3 based platforms and
thy all passed.
A new config option `sai_verify_incoming_chksum` was added to control the value of IPV4_INCR_CHECKSUM_ORIGINAL_VALUE_VERIFY in the EGR_FLEX_CONFIG control register (this prevents checksums of 0xffff from being propagated to other devices)

* Update default cable len to 0m for TD2 (#8298)
* Update sonic-cfggen tests with the correct cable len
Signed-off-by: Neetha John <nejo@microsoft.com>
As part of the buffer reclamation efforts for TD2, setting the default cable len to 0m which means unused ports will have a cable len of 0m.
Why I did it
To align with the changes in Azure/sonic-swss#1830
How to verify it
- With the default cable len set to 0m and the associated changes in swss, CABLE_LENGTH table had '0m' set for unused ports and accordingly more space was reserved for the shared pool
- Cfggen tests passed with the cable len update
