- Why I did it
The latest upgrade of Mellanox hw-mgmt V7.0020.1300 introduced a couple new kernel modules for new Mellanox platforms that have yet to be upstreamed to the linux kernel.
As these new platforms do not have SONiC support we elected not to upstream these new drivers to sonic-linux-kernel but hw-mgmt expects them to exist which is causing a non-functional error on switch boot.
Feb 15 00:09:55.374130 r-leopard-simx-74 ERR systemd-modules-load[269]: Failed to find module 'emc2305'
Feb 15 00:09:55.374141 r-leopard-simx-74 ERR systemd-modules-load[269]: Failed to find module 'ads1015'
To resolve this we can patch hw-mgmt to no longer attempt to load these modules by default.
- How I did it
Added a SONiC patch to Mellanox hw-mgmt in order to remove the unused kernel modules which were not upstreamed to sonic-linux-kernel
- How to verify it
Boot switch and verify there are no error logs regarding kernel modules failing to load.
- Why I did it
New version of mellanox platform management code available adding support for new platforms and fixing bugs.
- How I did it
1. Updated the submodule
2. Updated makefile version references
3. Regenerated SONiC patches
- Why I did it
To fix an issue that hw-mgmt patches were not applied. One patch was already in upstream hw-mgmt package thus applying it again caused an error and no other patches were applied. Also, I did it to improve the Makefile, so that the make will fail in case patches fail to apply.
- How I did it
Removed obsolete patch, made applying patches a hard failure in the build.
- How to verify it
Run the make and verify patches are applied.

#### Why I did it
Updated hw-mgmt pointer to updated branch and to include new bugfixes. The hw-mgmt submodule was previously pointing to an orphaned commit which could not be fetched from github, this has now been resolved.
#### How I did it
Updated submodule pointer.
#### How to verify it
Clone down repository and update all submodules.
Allow mellanox platform to build and successfully switch packets in
Debian 11
Upgraded
* Mellanox SDK
* Mellanox Hardware Management
* Mellanox Firmware
* Mellanox Kernel Patches
Adjusted build system to support host system running bullseye and

Upgrade hw-mgmt to 7.0100.2303
Bug fixes
1. Fan direction feature fix for fixed FAN system (using shell instead of binutils/strings)
2. Remove cpld 4th link on systems with only 3 CPLD's
3. hw-mgmt: thermal: Add hardcoded critical trip point. Follow-up after patch "Removing critical thermal zones to prevent unexpected software system shutdown".
4. Fix sensor attribute mapping to be label based instead of index based to allow common handling of voltage regulator names independently of hardware changes.
5. Update 'lm-sensors' custom configuration file. Relevant only for users utilizing sensors.conf files coming along with hw-management package.
6. For full feature list please follow https://github.com/Mellanox/hw-mgmt/blob/V.7.0010.2300_BR/debian/Release.txt

- Why I did it
Bug fixes
- In rare cases when thermal algorithm is reactivated after FAN/PSU insertion, FAN remains at high rpm
- When stop hw-management code received error in the log instead of exit code '0'.
- In SPC1 i2c sometimes collide with chip reset coming from SDK
- Remove raw eeprom data link, when working with PSU which don't have eeprom for "msn274x", "msn24xx" and "msn27xx" systems
- Fix memory leak on mlxsw_core_bus_device module removal

- 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".

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.
**- Why I did it**
On the Mellanox platform, reboot cause is fetched from some certain sysfs which is created by the hw-management service. So determine-reboot-cause service shall start after hw-management, otherwise it could fail due to the related sysfs is not available yet.
**- How I did it**
Add a patch to the hw-management service to make sure determine-reboot-cause service should start after it.
