How I did it
Add sai_hash_seed_config_hash_offset_enable=1 in all config.bcm that Broadcom T1 uses.

8.4.35.0: [CSP 00012324019] back-porting SONIC-75006 to SAI8.4
8.4.34.0:
[CSP 00012318293] back-porting SONIC-81534 to SAI8.4;
ECMP LB traffic polarization, configure hash_offset along with hash_seed attr

How to verify it
use tests/ecmp/test_ecmp_sai_value.py to verify.
* [202205] Update SOC properties for DLR_INIT based pfcwd recovery (#15217)
Why I did it
Update soc properties for certain roles that need to use pfcwd dlr init based recovery mechanism
How to verify it
Updated the templates on a 7050cx3 dual tor and 7260 T1 which satisfies these conditions and validated pfcwd recovery which uses DLR_INIT based mechanism. Also validated that this mechanism is not used on 7050cx3 single tor with the updated templates

* [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.
* 7260cx3 DualToR config.bcm support based on DualToR setting in device metadata at boot time.
For HWSKU Arista-7260CX3-C64 the MMU setting SOC for T0/T1 is also combined into the config.bcm.j2 logic so use just one config file and adding delta based on Switch Roles.
