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**
- Platform API implementation using sonic-cfggen to get platform name and SKU name, which will fail when the database is not available.
- Chassis name is not correctly assigned, it shall be assigned with EEPROM TLV "Product Name", instead of SKU name
- Chassis model is not implemented, it shall be assigned with EEPROM TLV "Part Number"
**- How I did it**
1. Chassis
> - Get platform name from /host/machine.conf
> - Remove get SKU name with sonic-cfggen
> - Get Chassis name and model from EEPROM TLV "Product Name" and "Part Number"
> - Add function to return model
2. EEPROM
> - Add function to return product name and part number
3. Platform
> - Init EEPROM on the host side, so also can get the Chassis name model from EEPROM on the host side.
As part of consolidating all common Python-based functionality into the new sonic-py-common package, this pull request:
1. Redirects all Python applications/scripts in sonic-buildimage repo which previously imported sonic_device_util or sonic_daemon_base to instead import sonic-py-common, which was added to the 201911 branch in https://github.com/Azure/sonic-buildimage/pull/5063
2. Replaces all calls to `sonic_device_util.get_platform_info()` to instead call `sonic_py_common.get_platform()` and removes any calls to `sonic_device_util.get_machine_info()` which are no longer necessary (i.e., those which were only used to pass the results to `sonic_device_util.get_platform_info()`.
3. Removes unused imports to the now-deprecated sonic-daemon-base package and sonic_device_util.py module
This is a step toward resolving https://github.com/Azure/sonic-buildimage/issues/4999
* Change port index in port_config.ini to 1-based
* Add default port index to port_config.ini, change platform plugins to accept 1-based port index
* fix port index in sfp_event.py
* New SKU support for MSN3420

* [sonic_platform]remove the handling of reset_sw_reset which indicates rebooted by software.
* [sonic_platform]Check "reset_sw_reset"
Also check reboot cause file "reset_sw_reset" which indicates the system was rebooted due to software requesting.
*Currently get_firmware_version implementated by using chassis.get_firmware_version and chassis._component_name_list which are not supported in the latest sonic_platform_common, causing chassis broken. Update this part so that it aligns to the latest sonic_platform_common
*Support component API
optimize SFP module operations and fix issues.
- split initialization of variant categories of devices and initialize each category of devices only when needed, so that unnecessary dependencies can be avoided.
- update watchdog logic, only initializing watchdog when referenced.
- support platform.py and enable to initialize variant devices on a host/docker basis
- update init so that sonic_platform can be imported as a whole.
* [Mellanox]refractor the sfp event change notification logic for new platform api
remove the standalong daemon which is in charge of polling sfp change event through sdk interface
and move the polling stuff to the event in the chassis daemon.
* rephase some comment
* fix typo in sfp_event.sfp_event.initialize
* support new platform api, thermal and psu part
for psu, all APIs are supported.
for thermal, we support
get_temperature,
get_high_threshold
for the thermal sensors of cpu core, cpu pack, psu and sfp module
and get_temperature for the ambient thermal sensors around the asic, port, fan, comex and board.
* 1. address review comments
2. improve the handling of PSU inserting/removal
3. tolerance diverse psu thermal sensor file name conventions
* 1. adjust thermal code according to the latest version of hw-management
2. check power_good_status rather than whether file existing ahead of reading voltage, current and power of PSU
* new platform api, chassis part
* Inject mlnx mlx libs to platform monitor
* address the review comments
* remove some confusing naming.
* Adjust the minor cause to a more human-readable way when rebooted by firmware
* address review comments
* expose host dir /host/reboot-cause to pmon docker so that the reboot causing by user command can be identified
* 1. Revert "expose host dir /host/reboot-cause to pmon docker so that the reboot causing by user command can be identified"
Since the only hardware-causing reboot should be handled by get_reboot_cause and the logic of handling reboot cause is about to move to the host side, no need to mount this dir to pmon docker.
This reverts commit 3feb96869d.
2. adjust log output by using sonic_daemon_base.daemon_base.Logger.
3. remove the logic of verifying /host/reboot-cause/ files.
4. fix typo.
* implement get_firmware_version and adjust the interfaces regarding components' version retrieving according to the Azure/sonic-platform-common#34
