- Why I did it
Support DSCP remapping in dual ToR topo on T0 switch for SKU Mellanox-SN4600c-C64, Mellanox-SN4600c-D48C40, Mellanox-SN2700, Mellanox-SN2700-D48C8.
- How I did it
Regarding buffer settings, originally, there are two lossless PGs and queues 3, 4. In dual ToR scenario, the lossless traffic from the leaf switch to the uplink of the ToR switch can be bounced back.
To avoid PFC deadlock, we need to map the bounce-back lossless traffic to different PGs and queues. Therefore, 2 additional lossless PGs and queues are allocated on uplink ports on ToR switches.
On uplink ports, map DSCP 2/6 to TC 2/6 respectively
On downlink ports, both DSCP 2/6 are still mapped to TC 1
Buffer adjusted according to the ports information:
Mellanox-SN4600c-C64:
56 downlinks 50G + 8 uplinks 100G
Mellanox-SN4600c-D48C40, Mellanox-SN2700, Mellanox-SN2700-D48C8:
24 downlinks 50G + 8 uplinks 100G

Why I did it
The 720DT-48S platform has variants with different chassis names, and these need to all be included in platform_components.json to ensure that sonic-mgmt platform_tests/fwutil/test_fwutil.py::test_fwutil_show passes
How I did it
Updated platform_components.json with the variant names for 720DT-48S.
How to verify it
Ran aforementioned testcase and verified that it passes on the different variants.

Why I did it
autoneg is not supported in the previous release 202012 on Nokia-7215 platform. To migrate to the 202205 image with autoneg support, we need to disable the autoneg to allow the link to be up when issue load minigraph. This requires to change the autoneg setting to be off in the port_config.ini file.
How I did it
Modify the port_config.ini to set the autoneg off.
How to verify it
Running the new image, with load mingraph.xml, execute "show int autonet status" should show autoneg disabled
Why I did it
To bring in the following fixes:
Revert temporary fix added to disable SA equal DA drops
CS00012273013 - [7.1][J2, J2c+] Disable SA Equals DA trap on DNX
CS00012274222 - How to block the voq for given destination port for a flow from a remote mod-id
CS00012275381 - SAI_INGRESS_PRIORITY_GROUP_STAT_PACKETS is incremented for port's PG's even if there are no traffic sent to that PG
CS00012274433 - Local Fault and Remote Fault are not polled by linkscan thread
How I did it
Merged above fixes to SAI code
How to verify it
Validated by running the basic sanity tests on XGS and DNX chassis platforms including
fib/test_fib.py
decap/test_decap.py
drop_counters/test_drop_counters.py

Why I did it
Update the Nokia-7215 device data which is required by the new version of the Marvell SAI 1.10.2-2 to fix the syncd crash issue.
How I did it

Why I did it
This is to fix test_forward_ip_packet_with_0xffff_chksum_tolerant test failure on 720DT-48S. IP packets with checksum set to 0xffff will be forwarded with the same checksum on this platform, instead of updating to the correct value.
How I did it
Add bcm config sai_verify_incoming_chksum=0 so that checksum is updated instead of being left unchanged when checksum is 0xffff. Note that packets with invalid checksum are still dropped with this config.

Add missing aggregate port_config.ini needed by sonic-mgmt
Concatenate the ASIC specific port_config.ini from device/arista/x86_64-arista_7800r3a_36d2_lc/Arista-7800R3A-36D2-C36/[01] to create the aggregate file.
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:
Fix multiple seastone platform issues caused by sonic kernel upgrade.
How I did it:
Get gpio base id with new label path in gpio sys fs.
How to verify it:
After the change, show platform fan/psustatus/temperature works well.

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
Why I did it
Added to allow test_crm_route to pass; the test tries to add a /126 ipv6 route and this change is required in order for the count of available routes to be updated correctly.
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.

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

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.

changed the platform device name under nokia directory; we now need to specify marvell armhf/arm64 to provide more accurate platform identity. otherwise onie discovery won't recognize the asic being installed.
Why I did it
when we load images using onie discovery, the process was failing because of marvell ASIC mismatch
How I did it
replace the platform asic with marvell-armhf under 7215
How to verify it
load a new image using http server and verify that the image can be loaded successfully
