(Test) Deprecating Python2 platform daemons		MSFT	Dell			N/A		All platform daemons will run using Python 3. Python 2 support will be removed. Vendors must build and install Python 3 sonic-platform packages. Question: Will there be new platform APIs to be added in 202111? @Guohan to confirm
MACSEC enhancement: primary & fallback case		MSFT	BRCM Juniper			No		MACsec can enable primary and fallback Connectivity Association Keys(CAK) at a same time. Meanwhile the primary and fallback key can be switched or replaced without any outage.
DHCP relay IPv6 support HLD - Merged	March 30	Nvidia	BRCM	10 May	7772&6531 - Open 7789&3565 - Merged	No		Currently DHCP relay supports only IPv4. The idea is to extend the support to IPv6 and it should work for both as the same time. Also, currently DHCP relay is enabled only based on the Type in the METADATA and it must be ‘ToRRouter’. We will remove this restriction and will integrate it with copp manager so user can decide if to have DHCP relay or not regardless of the device type

ACL UDF		MSFT	Nvidia			No (use existing, vendors to implement)		Support user defined fields in ACL. Comment: Please align with Nvidia team as dynamic policy based hashing requires changes to edit flow.

Enhance SONiC init flow using query statistics SAI API	N/A	Nvidia	TBD			Yes		Utilize query statistics SAI API
Align crmorch with sai_object_type_get_availability		Nvidia	TBD			No PR 942		Will not require a new SAI API, but vendors will have to implement this API for using this functionality

CMIS Diagnostics		BRCM				No		Introduce the CMIS4 transceiver-specific diagnostic test to help users narrow down the root cause of link failures. Scope of the change: 1) sonic-platform-daemons/sonic-xcvrd: Add a new subprocess to subscribe CMIS diag requests and either update DIAG control or post the test result to the RedisDB. 2) sonic-platform-common/sonic_platform_base: Add a generic QSFPDD/CMIS4 parser/handler to sfp_standard. [sfp_standard.py]py 3) sonic-mgmt-common: Add YANG and REST transformer codes for CMIS DIAG
TDR support for 1G Cu SFP		BRCM				No		Introduce time-domain reflectometer test support for 1000BASE-T Cu SFP. Scope of the change 1) sonic-linux-kernel: Update the optoe driver to add Cu SFP support (i.e. device address 0x56). 2) sonic-platform-common/sonic_platform_base: Add a generic Cu SFP parser/handler to sfp_standard. [sfp_standard.py]py 2) sonic-platform-daemon/sonic-xcvrd: Add a new subprocess to subscribe for TDR requests in the APPL_DB and post the results to STATE_DB 3) sonic-mgmt-common: Add YANG and REST transformer codes for TDR
System Ready Enhancements		BRCM				No		Today there is no easy way to know when the device is ready in terms of control/dataplane. The change allows declaration of System ready (Syslog/CLI) when all the services(dockers+host) are up and ready. Also define a framework for each service to declare itself ready based on their application criteria.
Gear Box		BRCM				No		Additional enhancements to overcome existing limitations with the current community code
Routed sub-interface naming convention		BRCM				No		Linux kernel has a limitation of 15 character interface name size, modify the sub interface naming convention to keep it in short format (e.g. Eth100.1234, or Po100.1234). This naming change for subinterfaces will kept it uniform across the entire SONiC subsystem (config, show, and in all dbs) for the subinterfaces. DB migrator scripts are enhanced for the name conversion during the upgrade.
SNMPd Enhancements		BRCM				No		Enable ipv6 snmpd support. Generate coldStart/warmStart trap based on reboot reason to differentiate. Removed default SNMP community public for security. Add strerror to SNMP file open failure. There is a possibility for snmpd try to open a device file (for reading statistics) which is already deleted by other applications.
