sonic-mgmt xoff test was failing for [100g,120km]. Needed to update total headroom pool size when 100G line card is used as T2 uplink.
This size was calculated assuming 100g is used for downlink so cable length was 2km whereas it can also be used for uplink (cable length - 120km). so we need to do calculation based on 120km not 2km. Although it will be some wastage for 2km scenario but it should cover both cases.
* Updated default ECN settings for T2 chassis (#14388)
Why I did it
Update ECN settings for T2 chassis
How I did it
Updated qos config file to load these settings during switch bootup
How to verify it
Verified on line card on T2 chassis
* Fix for test failures
* Test case failures
* test case fix
Why I did it
Update cable length for uplink/downlink ports for chassis and and update PG/pool headroom size accordingly.

How I did it
Updated cable length as well as buffer config in HWSKU files.
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
