This change is to disable the pcie firmware check done by Broadcom SAI. The change is needed for the Arista platform x86_64-arista_7050cx3_32s; otherwise, the check will fail, blocking the initialization.
There was a pcie firmware check added in brcm SDK and certain Arista hardwares do not compliant with the check, so we added the disable_pcie_firmware_check originally for x86_64-arista_7060dx4_32. For x86_64-arista_7050cx3_32s, it was able to pass the check but some firmware change done in August made it fail.
Why I did it
Some sonic-mgmt platform_tests/api were failing on the 7060CX-32S
How I did it
Added the missing metadata in platform.json and platform_components.json
This is purely test data and does not impact our API implementation.
How to verify it
Run platform_tests / api and expect 100% pass rate.
Why I did it
The PR is to apply separated DSCP_TO_TC_MAP and TC_TO_QUEUE_MAP to uplink ports on dualtor.
The traffic with DSCP 2 and DSCP 6 from T1 is treated as lossless traffic.
DSCP TC Queue
2 2 2
6 6 6
Traffic with DSCP 2 or DSCP 6 from downlink is still treated as lossy traffic as before.
How I did it
Define DSCP_TO_TC_MAP|AZURE_UPLINK and TC_TO_QUEUE_MAP|AZURE_UPLINK.
How to verify it
Verified by UT
Verified by coping the new template to a testbed, and rendering a config_db.json
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

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

This PR brings two changes
Add lossy PG profile for PG2 and PG6 on T1 for ports between T1 and T2.
After PR Update qos config to clear queues for bounced back traffic #10176 , the DSCP_TO_TC_MAP and TC_TO_PG_MAP is updated when remapping is enable
DSCP_TO_TC_MAP
Before After Why do this change
"2" : "1" "2" : "2" Only change for leaf router to map DSCP 2 to TC 2 as TC 2 will be used for lossless TC
"6" : "1" "6" : "6" Only change for leaf router to map DSCP 6 to TC 6 as TC 6 will be used for lossless TC
TC_TO_PRIORITY_GROUP_MAP
Before After Why do this change
"2" : "0" "2" : "2" Only change for leaf router to map TC 2 to PG 2 as PG 2 will be used for lossless PG
"6" : "0" "6" : "6" Only change for leaf router to map TC 6 to PG 6 as PG 6 will be used for lossless PG
So, we have two new lossy PGs (2 and 6) for the T2 facing ports on T1, and two new lossless PGs (2 and 6) for the T0 facing port on T1.
However, there is no lossy PG profile for the T2 facing ports on T1. The lossless PGs for ports between T1 and T0 have been handled by buffermgrd .Therefore, We need to add lossy PG profiles for T2 facing ports on T1.
We don't have this issue on T0 because PG 2 and PG 6 are lossless PGs, and there is no lossy traffic mapped to PG 2 and PG 6
Map port level TC7 to PG0
Before the PCBB change, DSCP48 -> TC 6 -> PG 0.
After the PCBB change, DSCP48 -> TC 7 -> PG 7
Actually, we can map TC7 to PG0 to save a lossy PG.
How I did it
Update the qos and buffer template.

#### 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
```

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
To support dynamic port breakout Broadcom configurations on Arista platforms.
How I did it
Updated platform.json for platforms and added new hwsku, Broadcom config, and hwsku.json for dynamic port breakout usage.
The name of the new hwsku name used is very similar to the platform name (platform x86_64-arista_7050_qx32s hwsku Arista-7050QX-32S) as the flex hwsku is meant to be the default in the future.
How to verify it
Boot up device with the new hwsku, interfaces are up.
Change hwsku.json with new default breakout mode and reload device, breakout will have successfully been applied.
Set hierarchical ecmp level to 2 instead of 3. Based on CS00011833367, ecmp level must be set to 2.
This is already handled for TH2 platforms. Change is required only for TD3

Port_config update for hwsku 7050CX3-32S-C3 - add two 10G ports.
This change is added to fix issue of "PortsOrch initialization failure" seen by previous removal of these 10G ports.
Tested on the device with new minigraph, and the PortsOrch initialization failure is not seen.
port_config.ini for HWSKU Arista-7050CX3-32S-C32 has missing speed column and duplicated lanes.
The incorrect speed causes issues in Orchagent RESTARTCHECK as the below task remains as the remaining item during swss shutdown.
Prevent system-healthd from service from failing at boot time due to missing configuration.
Also adds basic support for healthd.
The following caveat exists with this placeholder configuration:
- No PSU monitoring (sensors/fans)
- No ASIC temperature monitoring
platform.json is needed for sonic-mgmt testing. Also in the future it will be used as part of dynamic port breakout.
Also removed the folder symlink for BlackhawkDD because it has a different platform.json than BlackhawkO.

- How I did it
Added these MMU configuraions are copied from another platform and guaranteed to be incorrect for hwsku Arista-7050CX3-32S-C32.
Adding them so that we have A MMU configuration and the system won't throw a whole bunch of errors and leave MMU unconfigured. The correct MMU configuration will come later.
This configuration is definitely not suitable for testing system performance or QoS behavior.
