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
By specifying 'status_led' 'controllable' to false for psu section, it means the platform is not yet supporting psu status led
How I did it
specify 'status_led' 'controllable' to false for psu section
How to verify it
by running test in pdb, manually add {'status_led' : {'controllable' : False}} in dictionary
this flag will be able to get False and skip testing:
ce290c735d/tests/platform_tests/api/test_psu.py (L337)
After upgrade to brcmsai 8.1, the sdk running environment (container) recommended with mininum memory size as below
TH4/TD4(ltsw) uses 512MB
TH3 used 300MB
Helix4/TD2/TD3/TH/TH 256 MB
Base on this requirement, adjust the default syncd share memory size and set the memory size for special ACISs in platform_env.conf file for different types of Broadcom ASICs.
How I did it
Add the platform_env.conf file if none of it for broadcom platform (base on platform_asic file)
Add the 'SYNCD_SHM_SIZE' and set the value
for ltsw(TD4/TH4) devices set to 512M at least (update the platform_env.conf)
for Td2/TH2/TH devices set to 256M
for TH3 set to 300M

Eariler the SDK stat polling was erroneously set to once every msec
which is far more frequent than required by SWSS. The new setting, which
is consistent with other vendor SKUs, is once a second. The net result
is reduced CPU MHz by syncd.
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.
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
TX FIR tuning should be done based on the type of inserted transceiver

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.

Verified by UT
Verified by coping the new template to a testbed, and rendering a config_db.json

Some Arista products do not have an SSD but use an eMMC instead.
The SsdUtil plugin is therefore extended to support both.
How I did it
Implemented ssd_util.py platform plugin loaded by ssdutil.
This plugin fallback to the default SONiC implementation if the arista one can't be found.
How to verify it
Run show platform ssdhealth on a product with an eMMC
Multi-asic Docker instances are created behind Docker's default bridge
which doesn't allow talking to other Docker instances that are in the
host network (like database-chassis).
On linecards, we configure midplane interfaces to let per-asic docker
containers talk to CHASSIS_DB on the supervisor through internal chassis
network.
On the supervisor we don't need to use chassis internal network, but we
still need a similar setup in order to allow fabric containers to talk
to database-chassis

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.

Update TC_TO_QUEUE_MAP|AZURE , and test cases as well.

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
