* [Nokia ixs7215] Miscellaneous platform API fixes
This commit delivers the following fixes for the Nokia ixs7215 platform
- Fix bug in a fan API error path
- Add support for setting the fan drawer led
- Add support for getting/setting the front panel PSU status led
- Add support for getting the min/max observed temperature value
* [Nokia ixs7215] code review changes: temperature min/max values
Why I did it
Power cycle test case fails for Z9332f in sonic-mgmt framework(#8605).
How I did it
Modified the platform API to return expected strings.
How to verify it
Power cycle the device and verify the reboot reason.
Run sonic-mgmt test_reboot script.
- Why I did it
Update SDK\FW version to 4.4.3326\2008.3326. This version contains:
New Features:
1. Add support for Fast Boot for SN3800
Bug Fixing:
1. In some cases, when the total number of allocations exceeds the resource limit, an error can occur due to incorrect resource release procedure. This issue is most likely to affect the following resources: flow counters, ACL actions, PBS, WJH filter, Tunnels, ECMP containers, MC (L2 &L3)
2. On Spectrum systems, when using Async Router API with IPV6, an error message in the log regarding failing to remove ECMP container may show up. This error is not functional and can be safely ignored.
3. On Spectrum-2 systems and above, when using warm boot, setting max_bridge_num to a value greater than 1968 will cause an error and potential crash.
4. Some Molex cables do not support speed after reboot
- How I did it
Update submodule and .mk files
- How to verify it
Verified by running regression tests that includes complete sonic-mgmt tests supported

This commit adds support for changing the default console baud rate configured
within the U-Boot bootloader. That default baud rate is exposed via the value
of the U-Boot 'baudrate' environment variable. This commit removes logic that
hardcoded the console baud rate to 115200 and instead ensures that the U-Boot
'baudrate' variable is always used when constructing the Linux kernel boot
arguments used when booting Sonic.
A change is also made to rc.local to ensure that the specified baud rate is set
correctly in the serial getty service.
#### Why I did it
New PSU could install different type of fan, so fan max/min speed should be read per PSU
#### How I did it
The existing implementation read PSU max/min fan speed from a common file, change it to read from per PSU file
#### How to verify it

Why I did it
BIOS upgrade on rare cases cannot guarantee bus value remain the same on every BIOS release. Ignoring this field in order for pcied not to fail but still verify device id in a different way. The solution is future proof and will not require changes in code when new BIOS version is available
How I did it
Since bus is not a fixed value (it is determined by the bios version) we are ignoring this field, and instead checking if there is a device that match on all other fields that and in addition has a matching device id.
How to verify it
Verify no errors or failures in pcied on different BIOS version with the same code base.

Why I did it
There were two regression issues introduced by BRCM SAI 4.3.3.8:
CS00012196056 [4.3.3.8][WARMBOOT] syncd[2584]: segfault at 5616ad6c3d80 ip 00007f61e0c6bc65 sp 00007fff0c5a7a90 error 4 in libsai.so.1.0[7f61e0a95000+3cd8000]
CS00012195956 [4.3.3.8] [TD3]Syncd Crash at brcm_sai_tnl_mp_create_tunnel()
How I did it
Patch for CS00012195956 from BRCM was validated to have addressed the tunnel creation issue.
Temporary worked around the issue by commenting out a portion of questionable code in BRCM SAI that seems to be the root cause of CS00012196056 .

Why I did it
Currently we leveraged the Supervisor to monitor the running status of critical processes in each container and it is more reliable and flexible than doing the monitoring by Monit. So we removed the functionality of monitoring the critical processes by Monit.
How I did it
I removed the script process_checker and corresponding Monit configuration entries of critical processes.
How to verify it
I verified this on the device str-7260cx3-acs-1.
This is due to the fact that we use SONIC_OVERRIDE_BUILD_VARS internally
in our build jobs and this is not accounted in caching framework.
So we add MLNX_SDK_DEB_VERSION to force rebuild if we changed it via
SONIC_OVERRIDE_BUILD_VARS.

#### Why I did it
- After [sonic-linux-kernel#177](https://github.com/Azure/sonic-linux-kernel/pull/177) changes, the I2C mux channels of Baseboard and Switchboard CPLDs are moved from i2c-4 and i2c-5 to i2c-36 and i2c-37 respectively.
- This caused QSFP driver initialization of i2c-36 to i2c-41 to fail causing the ports from Ethernet208 to Ethernet248 fail.
#### How I did it
- The fix to this problem is to change the order of QSFP driver initialization to I2C mux channels.
- Instead of the order i2c-10 to i2c-41, the order i2c-4 to i2c-35 is being utilized.
- Also, need to change the i2c-mux-channel number for Baseboard CPLD and switchboard CPLD in scripts to access them.
#### Why I did it
On our platforms syncd must be up while using the sonic_platform.
The issue is warm-reboot script first disables syncd then instantiate Chassis, which tries to connect syncd in __init__.

This pull request is based on as9716-32d, so I reference as9716-32d to create new model: as9726-32d.
This module do not need led driver to control led, FPGA can handle it.
I also implement API2.0(sonic_platform) for this model, CPLD driver, PSU driver, Fan driver to control these HW behavior.
Why I did it
Fix issues below.

This is to pick up BRCM SAI 4.3.3.5-2 which contains 2 main changes:
1. hsdk-6.5.21-p1.patch (to address some field problems related to SDK issue.
2. Fix for CS00012097141 (remove some unnecessary debug setting that was causing non functional impacting problem at boot time)
Preliminary tests looks fine. BGP neighbors were all up with proper routes programmed

LED_PROC_INIT_SOC variable was incorrectly referenced as LED_SOC_INIT_SOC. Introduced in #5483
Rather than fixing the typo, I decided to simplify the script, removing the need for the conditional altogether by moving the bcmcmd call inside the conditional which checks for the presence of LED_SOC_INIT_SOC.
#### Why I did it
- PSU data is loaded into state DB.
Following errors are seen in syslogs:
"Failed to update PSU data - '<=' not supported between instances of 'float' and 'str'"
- Issue is not seen in master image as the PSU API return type is different.

CS00011227466: [4.3] Warmboot support with tunnel encap
- Why I did it
The existing Fan led and Psu led object initialize itself to green color in init method. However, there are multiple daemons calls sonic platform API and there could be a case that:
A PSU is removed from system
Reboot switch
psud detects that 1 PSU is missing and set PSU led to red
Other daemon just start up and call sonic platform API, the API set PSU led to green by call PsuLed.init
This PR is a partial fix for the issue. As we also need guarantee that the led is initialized with a correct value. I checked existing psud and thermalctld code. psud always initialize the PSU led color on boot up, thermalcltd need some changes to initialize led color on the first run
- How I did it
Remove the led color initialization code from FanLed.init and PsuLed.init
- How to verify it
Manual test
Eliminate the need for `gbsyncd_start.sh`, which simply calls `exec "/usr/bin/gbsyncd_startup.py"`. The shell script is unnecessary.
Once this PR merges, we can remove `gbsyncd_start.sh` from the sonic-sairedis repo.

This PR is needed to fix the show interface counters output issue where the counters are not correct due to an issue introduced in BRCM SAI 4.3.

Without the fix if one injects packets, the expected counters for the interfaces involved do not show correct count values. The RX count looks to be TX count while TX count looks to be RX count but even that the values could not be trusted.
After the fix the counters started to look correct. Here is one sample output taken after the fix is applied where I manually injected 10,000 packets into Ethernet92 to be routed out of the port channel member port Ethernet40. Also injected 10,000 invalid packets into the same Ethernet92 and all 10,000 packets were shown RX_DRP correctly.

It seems that starting with BRCM SAI 4.2.1.5 syncd is using ethtool to set the host interface speed and since this ethtool was not part of the syncd Docker, we observe these "ethtool not found" issue.
**- Why I did it**
sonic-utilities will become dependent upon sonic-platform-common as of https://github.com/Azure/sonic-utilities/pull/1386.
**- How I did it**
- Add sonic-platform-common as a dependency in docker-sonic-vs.mk
- Additionally, no longer install Python 2 packages of swsssdk and sonic-py-common, as they should no longer be needed.
- Why I did it
Initially, we used Monit to monitor critical processes in each container. If one of critical processes was not running
or crashed due to some reasons, then Monit will write an alerting message into syslog periodically. If we add a new process
in a container, the corresponding Monti configuration file will also need to update. It is a little hard for maintenance.
Currently we employed event listener of Supervisod to do this monitoring. Since processes in each container are managed by
Supervisord, we can only focus on the logic of monitoring.
- How I did it
We borrowed the event listener of Supervisord to monitor critical processes in containers. The event listener will take
following steps if it was notified one of critical processes exited unexpectedly:
The event listener will first check whether the auto-restart mechanism was enabled for this container or not. If auto-restart mechanism was enabled, event listener will kill the Supervisord process, which should cause the container to exit and subsequently get restarted.
If auto-restart mechanism was not enabled for this contianer, the event listener will enter a loop which will first sleep 1 minute and then check whether the process is running. If yes, the event listener exits. If no, an alerting message will be written into syslog.
- How to verify it
First, we need checked whether the auto-restart mechanism of a container was enabled or not by running the command show feature status. If enabled, one critical process should be selected and killed manually, then we need check whether the container will be restarted or not.
Second, we can disable the auto-restart mechanism if it was enabled at step 1 by running the commnad sudo config feature autorestart <container_name> disabled. Then one critical process should be selected and killed. After that, we will see the alerting message which will appear in the syslog every 1 minute.

During ISSU, "mlxsw_minimal" driver still trying to access firmware, in some cases FW could return some wrong critical threshold value which will cause switch shutdown.
**- How I did it**
In order to prevent "mlxsw_minimal" driver from accessing ASIC during ISSU, SDK will raise "OFFLINE" 'udev' event
at the early beginning of such flow. When this event is received, hw-management will remove "mlxsw_minimal" driver.
There is no need to implement the opposite "ONLINE" event since this flow is ended up with "kexec".
**- How to verify it**
repeatedly perform warm reboot, make sure there is no switch shutdown occurred.

All | Modules, Port split | FW stuck when device rebooted with locked Optical Transceivers in split mode
