- 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

#### 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
Manual test
- Why I did it
New release of MFT has the following changelog / RN
Fixed an issue that resulted in getting MVPD read errors from the mlxfwmanager during fast reboot.
Fixed mlxuptime sometimes generating a time less than previous due the wrong frequency calculation
- How I did it
Update makefile pointer to new version.
- How to verify it
Manually tested on all Mellanox platforms.
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
to prevent python exception error when executing warm-reboot command on mellanox simulator platform
- How I did it
return None on the watchdog python script on cases that watchdog file is not exist
- How to verify it
warm-reboot is running well without the python error. error message will appear on log on these cases.
in order to avoid this error message we can simulate the watchdog on mellanox simulator platform
Update FW version to 2008.3218, fixing the following issues:
- 50G/100G links that are operationally down before warm-reboot are not coming up after warm-reboot
- 50G/100G links with admin shut / no shut commands are not coming up after warm-reboot

Enhance the Python3 support for platform API. Originally, some platform APIs call SDK API which didn't support Python 3. Now the Python 3 APIs have been supported in SDK 4.4.3XXX, Python3 is completely supported by platform API
- How I did it
Start all platform daemons from python3
1. Remove #/usr/bin/env python at the beginning of each platform API file as the platform API won't be started as daemons but be imported from other daemons.
2. Adjust SDK API calls accordingly

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.

Adopt a single way to get fan direction for all ASIC types.
It depends on hw-mgmt V.7.0010.2000.2303. Depends on https://github.com/Azure/sonic-buildimage/pull/7419
#### How I did it
Originally, the get_direction was implemented by fetching and parsing `/var/run/hw-management/system/fan_dir` on the Spectrum-2 and the Spectrum-3 systems. It isn't supported on the Spectrum system.
Now, it is implemented by fetching `/var/run/hw-management/thermal/fanX_dir` for all the platforms.

The following error message is observed during chassis object being destroyed
"Exception ignored in: <function Chassis.__del__ at 0x7fd22165cd08>
Traceback (most recent call last):
File "/usr/local/lib/python3.7/dist-packages/sonic_platform/chassis.py", line 83, in __del__
ImportError: sys.meta_path is None, Python is likely shutting down
The chassis tries to import deinitialize_sdk_handle during being destroyed for the purpose of releasing the sdk_handle.
However, importing another module during shutting down can cause the error because some of the fundamental infrastructures are no longer available."
This error occurs when a chassis object is created and then destroyed in the Python shell.
- How I did it
To fix it, record the deinitialize_sdk_handle in the chassis object when sdk_handle is being initialized and call the deinitialize handler when the chassis object is being destroyed
- How to verify it
Manually test.

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

It is proper object-oriented methodology to call the base class initializer, even if it is only the default initializer. This also future-proofs the potential addition of custom initializers in the base classes down the road.
- Why I did it
System is stuck on 'starting' state on SimX platform because of infinite loop on 'hw-management-ready.sh' script .
The loop is polling to check if the hw-mgmt sysfs created before proceeding with the flow, for SimX platform the sysfs will never create so the system is not starting properly.
- How I did it
Add a condition to poll on hw-mgmt sysfs only if the switch is real HW and not SimX platform.
- How to verify it
Check "systemctl status hw-management.service" output on a SimX switch with this patch, the state will be "active".
