This change was submitted directly to 202205 but it's also needed in master and 202305 with SAI9.x
#13346
There has been a couple CSPs for this as well:
CS00012273013 - [7.1][J2, J2c+] Disable SA Equals DA trap on DNX
CS00012320965 - SAI9.2: iBGP doesn't work due to SA_EQUALS_DA trap
If SA_EQUALS_DA trap is enabled iBGP won't work as the Ethernet-IB0 ports are expected to get packets with SA==DA.
In the VOQ chassis design, for outgoing control plane packets, the packets goes the recycle port for routing, therefore the dmac of the packet should be the asic router mac. The source mac is assigned by the kernel, so it is also the asic router mac.
* Update PG headroom settings ports based on port speed/cable length
* Updated XOFF settings to use chip level numbers than core
* Updated PG headroom based on uplink/downlink side
* fix for sonic-config-gen tests
* More fixes for unit test cases
* more test fixes
* Merged multiple functions into one
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
Why I did it
Support Egress Mirroring on supported Arista platforms
How I did it
Add necessary soc properties for egress mirroring recycle ports to be created

Updated asic_port_names for all Arista LC SKUs to follow latest naming
conventions to remove redundant ASICx suffix. For
Arista-7800R3-48CQ2-C48, added the asic_port_name mapping.
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.
Port indexes of front panel ports are not contiguous in multi-asic because we didn't distiguish between
front panel and internal ports, e.g., recycle ports. Fix this by assigning index to front panel port first
and then internal ports.
For 7800 LCs, set LAG mode to support 1024 number of 16-member system
LAGs.
Why I did it
The SOC property changes are necessary to match #10519 which increases the number of system LAG IDs to 1024.
Description for the changelog
For 7800 LCs, set LAG mode to support 1024 number of 16-member system
LAGs.
