**- Why I did it**
For decoding system EEPROM of S6000 based on Dell offset format and S6000-ON’s system EEPROM in ONIE TLV format.
**- How I did it**
- Differentiate between S6000 and S6000-ON using the product name available in ‘dmi’ ( “/sys/class/dmi/id/product_name” )
- For decoding S6000 system EEPROM in Dell offset format and updating the redis DB with the EEPROM contents, added a new class ‘EepromS6000’ in eeprom.py,
- Renamed certain methods in both Eeprom, EepromS6000 classes to accommodate the plugin-specific methods.
**- How to verify it**
- Use 'decode-syseeprom' command to list the system EEPROM details.
- Wrote a python script to load chassis class and call the appropriate methods.
UT Logs: [S6000_eeprom_logs.txt](https://github.com/Azure/sonic-buildimage/files/4735515/S6000_eeprom_logs.txt), [S6000-ON_eeprom_logs.txt](https://github.com/Azure/sonic-buildimage/files/4735461/S6000-ON_eeprom_logs.txt)
Test script: [eeprom_test_py.txt](https://github.com/Azure/sonic-buildimage/files/4735509/eeprom_test_py.txt)
**- Why I did it**
- Skip thermalctld in DellEMC S6000, S6100, Z9100 and Z9264 platforms.
- Change the return type of thermal Platform APIs in DellEMC S6000, S6100 and Z9100 platforms to 'float'.
**- How I did it**
- Add 'skip_thermalctld:true' in pmon_daemon_control.json for DellEMC S6000, S6100, Z9100 and Z9264 platforms.
- Made changes in thermal.py, for 'get_temperature', 'get_high_threshold' and 'get_low_threshold' to return 'float' value.
**- How to verify it**
- Check thermalctld is not running in 'pmon'.
- Wrote a python script to load Chassis class and then call the APIs accordingly and verify the return type.
For detecting transceiver change events through xcvrd in DellEMC S6000, S6100 and Z9100 platforms.
- In S6000, rename 'get_transceiver_change_event' in chassis.py to 'get_change_event' and return appropriate values.
- In S6100, implement 'get_change_event' through polling method (poll interval = 1 second) in chassis.py (Transceiver insertion/removal does not generate interrupts due to a CPLD bug)
- In Z9100, implement 'get_change_event' through interrupt method using select.epoll().

Take advantage of an SDK environment variable to customize the location where sdk_socket exists.
In the latest SDK sdk_socket has been moved from /tmp to /var/run which is a better place to contain this kind of file.
However, this prevents the subdirs under /var/run from being mapped to different volumes. To resolve this, we take advantage of an SDK variable to designate the location of sdk_socket.
This requires every process that requires to access sdk_socket have this environment variable defined. However, to define environment variable for each process is less scalable. We take advantage of the docker scope environment variable to avoid that.
It depends on PR 4227

- Implemented fancontrol service to monitor S6000 fans and adjust fan speed w.r.t temperature.
- fancontrol.service starts the fancontrol script at startup.
- This script takes the average temperature by reading three sensors and configure FANS to appropritate RPM against the temperature.
- When the temperature is adjusted script will log in syslog for future reference.
- Also, script checks for faulty fans and report the status in syslog.

Fix the issue when an SFP module is plugged into a QSFP port via an adapter.
- How I did it
Originally the type of an SFP module is determined according to the SKU dictionary. However, it's possible that as SFP module is plugged into a QSFP port via an adapter. In this case, the EEPROM content will be parsed in the wrong format.
To address that we fetch the identifier value of an xSFP module and then get the type by parsing it.
