Support Mellanox-SN4600C-C64 as T1 switch in dual-ToR scenario
This is to port #11032 and #11299 from 202012 to master.
Support additional queue and PG in buffer templates, including both traditional and dynamic model
Support mapping DSCP 2/6 to lossless traffic in the QoS template.
Add macros to generate additional lossless PG in the dynamic model
Adjust the order in which the generic/dedicated (with additional lossless queues) macros are checked and called to generate buffer tables in common template buffers_config.j2
Buffer tables are rendered via using macros.
Both generic and dedicated macros are defined on our platform. Currently, the generic one is called as long as it is defined, which causes the generic one always being called on our platform. To avoid it, the dedicated macrio is checked and called first and then the generic ones.
Support MAP_PFC_PRIORITY_TO_PRIORITY_GROUP on ports with additional lossless queues.
On Mellanox-SN4600C-C64, buffer configuration for t1 is calculated as:
40 * 100G downlink ports with 4 lossless PGs/queues, 1 lossy PG, and 3 lossy queues
16 * 100G uplink ports with 2 lossless PGs/queues, 1 lossy PG, and 5 lossy queues

This PR brings two changes
Add lossy PG profile for PG2 and PG6 on T1 for ports between T1 and T2.
After PR Update qos config to clear queues for bounced back traffic #10176 , the DSCP_TO_TC_MAP and TC_TO_PG_MAP is updated when remapping is enable
DSCP_TO_TC_MAP
Before After Why do this change
"2" : "1" "2" : "2" Only change for leaf router to map DSCP 2 to TC 2 as TC 2 will be used for lossless TC
"6" : "1" "6" : "6" Only change for leaf router to map DSCP 6 to TC 6 as TC 6 will be used for lossless TC
TC_TO_PRIORITY_GROUP_MAP
Before After Why do this change
"2" : "0" "2" : "2" Only change for leaf router to map TC 2 to PG 2 as PG 2 will be used for lossless PG
"6" : "0" "6" : "6" Only change for leaf router to map TC 6 to PG 6 as PG 6 will be used for lossless PG
So, we have two new lossy PGs (2 and 6) for the T2 facing ports on T1, and two new lossless PGs (2 and 6) for the T0 facing port on T1.
However, there is no lossy PG profile for the T2 facing ports on T1. The lossless PGs for ports between T1 and T0 have been handled by buffermgrd .Therefore, We need to add lossy PG profiles for T2 facing ports on T1.
We don't have this issue on T0 because PG 2 and PG 6 are lossless PGs, and there is no lossy traffic mapped to PG 2 and PG 6
Map port level TC7 to PG0
Before the PCBB change, DSCP48 -> TC 6 -> PG 0.
After the PCBB change, DSCP48 -> TC 7 -> PG 7
Actually, we can map TC7 to PG0 to save a lossy PG.
How I did it
Update the qos and buffer template.
How to verify it
Verified by UT.
Update the bcm config file system_ref_core_clock_khz param to handlesystems with J2cplus linecards.
We need system_ref_core_clock_khz to be set to 1600000 for supporting j2 and j2cplus linecards on the same chassis.

What/Why I did:
Issue1: By setting up of ipvlan interface in interface-config.sh we are not tolerant to failures. Reason being interface-config.service is one-shot and do not have restart capability.
Scenario: For example if let's say database service goes in fail state then interface-services also gets failed because of dependency check but later database service gets restart but interface service will remain in stuck state and the ipvlan interface nevers get created.
Solution: Moved all the logic in database service from interface-config service which looks more align logically also since the namespace is created here and all the network setting (sysctl) are happening here.With this if database starts we recreate the interface.
Issue 2: Use of IPVLAN vs MACVLAN
Currently we are using ipvlan mode. However above failure scenario is not handle correctly by ipvlan mode. Once the ipvlan interface is created and ip address assign to it and if we restart interface-config or database (new PR) service Linux Kernel gives error "Error: Address already assigned to an ipvlan device." based on this:https://github.com/torvalds/linux/blob/master/drivers/net/ipvlan/ipvlan_main.c#L978Reason being if we do not do cleanup of ip address assignment (need to be unique for IPVLAN) it remains in Kernel Database and never goes to free pool even though namespace is deleted.
Solution: Considering this hard dependency of unique ip macvlan mode is better for us and since everything is managed by Linux Kernel and no dependency for on user configured IP address.
Issue3: Namespace database Service do not check reachability to Supervisor Redis Chassis Server.
Currently there is no explicit check as we never do Redis PING from namespace to Supervisor Redis Chassis Server. With this check it's possible we will start database and all other docker even though there is no connectivity and will hit the error/failure late in cycle
Solution: Added explicit PING from namespace that will check this reachability.
Issue 4:flushdb give exception when trying to accces Chassis Server DB over Unix Sokcet.
Solution: Handle gracefully via try..except and log the message.

Moreover, /sbin/reboot invoked in the platform specific reboot script is a non-blocking call and thus it returns back to the original script (although /sbin/reboot does it job in the background) and we see messages like this.

- Accommodate relocated fan and thermal sysfs entries in bullseye
- Add support for chassis and PSU HW revision
Why I did it
Fix platform issues introduced by the bullseye kernel upgrade.
How I did it
Minor fixes to Nokia ixs7215 platform code
How to verify it
Execute the following CLI commands
show platform summary
show platform fan
show platform temperature
Why I did it
The current code assumes that the value part does not have whitespace. So everything after the whitespace will be ignored. The syseeprom values returned from platform API do not match the output of "show platform syseeprom" on dx010 and e1031 device.
How I did it
This change improved the regular expression for parsing syseeprom values to accommodate whitespaces in the value.
PR 10021 provides the solution, but committed to the wrong place for dx010 and e1031.
How to verify it
Compile the sonic_platform wheel for dx010, then upload to device and install the wheel, verify the platform eeprom API.

Why I did it
Linux kernel 5.10, 'force_deselct_on_exit' parameter used for driver i2c_mux_pca954x is no longer valid. Instead an attribute 'idle_state' is added per MUX device. So set idle_state=-2 will let do deselect to pca954 when device channel exit . To avoid cause another device channel access i2c fail.

Remove force_deselect_on_exit because not use this parameter.
Add "idle_state":"-2" to each "virt_bus"
How to verify it
Test all sysfs are fine.

This PR also adds the commit in sonic-platform-daemons
94fa239 [y_cable] refactor y_cable to a seperate logic and new daemon from xcvrd (#219)
Why I did it
This PR separates the logic of Y-Cable from xcvrd. Before this change we were utilizing xcvrd daemon to control all aspects of Y-Cable right from initialization to processing requests from other entities like orch,linkmgr.
Now we would have another daemon ycabled which will serve this purpose.
Logically everything still remains the same from the perspective of other daemons.
it also take care aspects like init/delete daemon from Y-Cable perspective.
How I did it
To serve the purpose we build a new wheel sonic_ycabled-1.0-py3-none-any.whl and install it inside pmon.
We also initalize the daemon ycabled which serves our purpose for refactor inside pmon

Requirements from Microsoft for fwutil update all state that all firmwares which support this upgrade flow must support upgrade within a single boot cycle. This conflicted with a number of Mellanox upgrade flows which have been revised to safely meet this requirement.
How I did it
Added --no-power-cycle flags to SSD and ONIE firmware scripts
Modified Platform API to call firmware upgrade flows with this new flag during fwutil update all
Added a script to our reboot plugin to handle installing firmwares in the correct order with prior to reboot
How to verify it
Populate platform_components.json with firmware for CPLD / BIOS / ONIE / SSD
Execute fwutil update all fw --boot cold
CPLD will burn / ONIE and BIOS images will stage / SSD will schedule for reboot
Reboot the switch
SSD will install / CPLD will refresh / switch will power cycle into ONIE
ONIE installer will upgrade ONIE and BIOS / switch will reboot back into SONiC
In SONiC run fwutil show status to check that all firmware upgrades were successful
