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

* [device]: Add SAI checksum verify to TD3 config
* A new config option 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)

Why I did it
This PR is to add two extra lossless queues for bounced back traffic.
HLD sonic-net/SONiC#950
SKUs include
Arista-7050CX3-32S-C32
Arista-7050CX3-32S-D48C8
Arista-7260CX3-D108C8
Arista-7260CX3-C64
Arista-7260CX3-Q64
How I did it
Update the buffers.json.j2 template and buffers_config.j2 template to generate new BUFFER_QUEUE table.
For T1 devices, queue 2 and queue 6 are set as lossless queues on T0 facing ports.
For T0 devices, queue 2 and queue 6 are set as lossless queues on T1 facing ports.
Queue 7 is added as a new lossy queue as DSCP 48 is mapped to TC 7, and then mapped into Queue 7
How to verify it
Verified by UT
Verified by coping the new template and generate buffer config with sonic-cfggen
* [Tunnel PFC] Add property for tunnel PFC
Replace the config.bcm file with j2 template file
- Add 'sai_remap_prio_on_tnl_egress=1' property when device metadata local
- Host subtype is 'dualtor'
- Change sai.profile foe the new config.bcm.j2
* [device config] Adding configuration for default route fallback
* Set sai_tunnel_underlay_route_mode attribute to fallback to default route if more specific route is unavailable.

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"
},

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.
Need A mmu configuration to get the device going without generating lots of warnings.
Similar to dummy MMU configuration for Arista-7050CX3-32S-C32, this configuration will need to be updated with correct numbers. This MMU configuration is copied from 7060 comparable hwsku.

- Why I did it
On Arista-7050CX3-32S-C32, there are constant stream of errors like following.
Nov 3 21:56:24.415190 str2-7050cx3-acs-06 NOTICE swss#orchagent: :- registerInWdDb: No lossless TC found on port Ethernet68
Which causes:
loganalyzer to claim test failed.
leaving the system without MMU configuration. Which couldn't be good for any IO test.
- 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.

Test will have chance to pass. Ran a few test that would fail otherwise.
However in SAI 3.7 default behaviout got changes to 128 Group and 128
Memeber each.
This change is to make sure we are using same ECMP Group/Memeber Per
Group for 3.7 also so that behaviour is consistent.
