Azure/sonic-utilities#1431 changes the path to the udevprefix.conf file. The file previously inappropriately resided in the <platform>/plugins/ directory. That directory is reserved for now-deprecated Python platform plugins, and will be removed in the near future.
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.
- How to verify it
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.
- Why I did it

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.

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.
Bugs fixes:
All | Kernel | During system reload when CPU is loaded with heavy traffic, a Kernel Panic may occur.
All | Modules, Port split | FW stuck when device rebooted with locked Optical Transceivers in split mode
Spectrum-3 | PFC | On Spectrum-3 systems, slow reaction time to Rx pause packets on 40GbE ports may lead to buffer overflow on servers.
Spectrum-3 | SN4700, Port Split | On rare occasion SN4700, conducting 100G split (4x25G) in NRZ when splitter port 1 or 2 are down, ports 3 and 4 will also go down.
Enahncments:
All | Kernel | new notification on ISSU start, so other kernel drivers can disable any interface to ASIC

- 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.

**- Why I did it**
To support dynamic buffer calculation.
This PR also depends on the following PRs for sub modules
- [sonic-swss: [buffermgr/bufferorch] Support dynamic buffer calculation #1338](https://github.com/Azure/sonic-swss/pull/1338)
- [sonic-swss-common: Dynamic buffer calculation #361](https://github.com/Azure/sonic-swss-common/pull/361)
- [sonic-utilities: Support dynamic buffer calculation #973](https://github.com/Azure/sonic-utilities/pull/973)
**- How I did it**
1. Introduce field `buffer_model` in `DEVICE_METADATA|localhost` to represent which buffer model is running in the system currently:
- `dynamic` for the dynamic buffer calculation model
- `traditional` for the traditional model in which the `pg_profile_lookup.ini` is used
2. Add the tables required for the feature:
- ASIC_TABLE in platform/\<vendor\>/asic_table.j2
- PERIPHERAL_TABLE in platform/\<vendor\>/peripheral_table.j2
- PORT_PERIPHERAL_TABLE on a per-platform basis in device/\<vendor\>/\<platform\>/port_peripheral_config.j2 for each platform with gearbox installed.
- DEFAULT_LOSSLESS_BUFFER_PARAMETER and LOSSLESS_TRAFFIC_PATTERN in files/build_templates/buffers_config.j2
- Add lossless PGs (3-4) for each port in files/build_templates/buffers_config.j2
3. Copy the newly introduced j2 files into the image and rendering them when the system starts
4. Update the CLI options for buffermgrd so that it can start with dynamic mode
5. Fetches the ASIC vendor name in orchagent:
- fetch the vendor name when creates the docker and pass it as a docker environment variable
- `buffermgrd` can use this passed-in variable
6. Clear buffer related tables from STATE_DB when swss docker starts
7. Update the src/sonic-config-engine/tests/sample_output/buffers-dell6100.json according to the buffer_config.j2
8. Remove buffer pool sizes for ingress pools and egress_lossy_pool
Update the buffer settings for dynamic buffer calculation

**- Why I did it**
We were building a custom version of Supervisor because I had added patches to prevent hangs and crashes if the system clock ever rolled backward. Those changes were merged into the upstream Supervisor repo as of version 3.4.0 (http://supervisord.org/changes.html#id9), therefore, we should be able to simply install the vanilla package via pip. This will also allow us to easily move to Python 3, as Python 3 support was added in version 4.0.0.
**- How I did it**
- Remove Makefiles and patches for building supervisor package from source
- Install Python 3 supervisor package version 4.2.1 in Buster base container
- Also install Python 3 version of supervisord-dependent-startup in Buster base container
- Debian package installed binary in `/usr/bin/`, but pip package installs in `/usr/local/bin/`, so rather than update all absolute paths, I changed all references to simply call `supervisord` and let the system PATH find the executable to prevent future need for changes just in case we ever need to switch back to build a Debian package, then we won't need to modify these again.
- Install Python 2 supervisor package >= 3.4.0 in Stretch and Jessie base containers

This change introduces PDDF which is described here: https://github.com/Azure/SONiC/pull/536
Most of the platform bring up effort goes in developing the platform device drivers, SONiC platform APIs and validating them. Typically each platform vendor writes their own drivers and platform APIs which is very tailor made to that platform. This involves writing code, building, installing it on the target platform devices and testing. Many of the details of the platform are hard coded into these drivers, from the HW spec. They go through this cycle repetitively till everything works fine, and is validated before upstreaming the code.
PDDF aims to make this platform driver and platform APIs development process much simpler by providing a data driven development framework. This is enabled by:
JSON descriptor files for platform data
Generic data-driven drivers for various devices
Generic SONiC platform APIs
Vendor specific extensions for customisation and extensibility

The orchagent and syncd need to have the same default synchronous mode configuration. This PR adds a template file to translate the default value in CONFIG_DB (empty field) to an explicit mode so that the orchagent and syncd could have the same default mode.
When detecting a new SFP insertion, read its SFP type and DOM capability from EEPROM again.
SFP object will be initialized to a certain type even if no SFP present. A case could be:
1. A SFP object is initialized to QSFP type by default when there is no SFP present
2. User insert a SFP with an adapter to this QSFP port
3. The SFP object fail to read EEPROM because it still treats itself as QSFP.
This PR fixes this issue.

**- Why I did it**
Install all host services and their data files in package format rather than file-by-file
**- How I did it**
- Create sonic-host-services Python wheel package, currently including procdockerstatsd
- Also add the framework for unit tests by adding one simple procdockerstatsd test case
- Create sonic-host-services-data Debian package which is responsible for installing the related systemd unit files to control the services in the Python wheel. This package will also be responsible for installing any Jinja2 templates and other data files needed by the host services.
Now we are reading base mac, product name from eeprom data, and the data read from eeprom contains multiple "\0" characters at the end, need trim them to make the string clean and display correct.
The `get_serial_number()` method in the ChassisBase and ModuleBase classes was redundant, as the `get_serial()` method is inherited from the DeviceBase class. This method was removed from the base classes in sonic-platform-common and the submodule was updated in https://github.com/Azure/sonic-buildimage/pull/5625.
This PR aligns the existing vendor platform API implementations to remove the `get_serial_number()` methods and ensure the `get_serial()` methods are implemented, if they weren't previously.
Note that this PR does not modify the Dell platform API implementations, as this will be handled as part of https://github.com/Azure/sonic-buildimage/pull/5609
Example of syslog message from Mellanox SAI:
"Oct 7 15:39:11.482315 arc-switch1025 INFO syncd#supervisord: syncd Oct 07 15:39:11 NOTICE SAI_BUFFER: mlnx_sai_buffer.c[3893]- mlnx_clear_buffer_pool_stats: Clear pool stats pool id:1"
There is a log INFO from supervisord which actually printed NOTICE and
date again. This confusion happens becuase if SAI is not built to log
to syslog it will log everything to stdout with format "[date] [level]
[message]" so supervisord sends it to syslog with level INFO.
New logs look like:
"Oct 7 15:40:21.488055 arc-switch1025 NOTICE syncd#SDK [SAI_BUFFER]: mlnx_sai_buffer.c[3893]- mlnx_clear_buffer_pool_stats: Clear pool stats pool id:17"

- The issue is that the SAI package content is changed without changing its version. The DPKG caches the wrong version of SAI package.
- The fix is to include the SAI package content header for SHA calcaulation. This will detect if there is any change in the SAI package.
It should no longer be necessary to explicitly install the 'wheel' package, as SONiC packages built as wheels should specify 'wheel' as a dependency in their setup.py files. Therefore, pip[3] should check for the presence of 'wheel' and install it if it isn't present before attempting to call 'setup.py bdist_wheel' to install the package.

We were building our own python-click package because we needed features/bug fixes available as of version 7.0.0, but the most recent version available from Debian was in the 6.x range.
"Click" is needed for building/testing and installing sonic-utilities. Now that we are building sonic-utilities as a wheel, with Click specified as a dependency in the setup.py file, setuptools will install a more recent version of Click in the sonic-slave-buster container when building the package, and pip will install a more recent version of Click in the host OS of SONiC when installing the sonic-utilities package. Also, we don't need to worry about installing the Python 2 or 3 version of the package, as the proper one will be installed as necessary.

Some platforms don't leverage the brcm led coprocessor.
However ledinit will try to load a non existing file and exit with an

Boot a platform without the configuration and verify in the syslog that the exit status of ledinit is 0
Boot a platform with the configuration and verify in the syslog that the exit status of ledinit is 0 and the leds are working.
Verified by adding a dumb led_proc_init.soc on an Arista platform which usually doesn't use it.
