Enable CMIS host management for Mellanox devices which are expected to support the feature
- How I did it
new thread in a new file and changing logic in platform code in chassis.py which is calling this thread from get_change_event()
this thread in the new file handles the state machine per port.
first the static detection takes place once the thread is up (during switch bootup sequence), until final decision if it's FW control or SW control module.
After it ends, the dynamic detection takes place, listening to changes in the sysfs fds, per port,
so it will be able to detect plug in or out events of a cable.

watchdogutil uses platform API watchdog instance to control/query watchdog status. In Nvidia watchdog status, it caches "armed" status in a object member "WatchdogImplBase.armed". This is not working for CLI infrastructure because each CLI will create a new watchdog instance, the status cached in previous instance will totally lose. Consider following commands:
admin@sonic:~$ sudo watchdogutil arm -s 100 =====> watchdog instance1, armed=True
Watchdog armed for 100 seconds
admin@sonic:~$ sudo watchdogutil status ======> watchdog instance2, armed=False

sfp_event.py gets a PMPE message when a cable event is available. In PMPE message, there is no label port available. Current sfp_event.py is using sx_api_port_device_get to get 64 logical ports attributes, and find the label port from those 64 attributes. However, if there are more than 64 ports, sfp_event.py might not be able to find the label port and drop the PMPE message.

Commit sonic-net/sonic-platform-daemons@153ea47 changed SfpStateUpdateTask from Process to Thread. In this commit, it raises an exception in SfpStateUpdateTask to make shutdown flow fast. But it does not work on Nvidia platform as Nvidia platform is passing timeout parameter of get_change_event to select. Linux select function can not be interrupted by a Python exception. There is no such issue on Nvidia platform before that commit. However, in order to comply with the commit and make shutdown flow fast, we decided to change Nvidia platform API implementation.
To fix issue #13591.
- How I did it
The select call in get_change_event should use no more than 1 second as timeout parameter.
Outside the select call, add a while loop to make sure timeout parameter of get_change_event work as expected

In case of warm/fast reboot, the hardware reboot cause will NOT be cleared because CPLD will not be touched in this flow. To not confuse the reboot cause determine logic, the leftover hardware reboot cause shall be skipped by the platform API, platform API will return the 'REBOOT_CAUSE_NON_HARDWARE' instead of the "hardware" reboot cause.

Check the proc cmdline to see whether the last reboot is a warm or fast reboot, if yes skip checking the leftover hardware reboot cause.

In order to prevent the sonic-mgmt/tests/platform_tests/sfp/test_sfputil.py test failing on the log analyzer step.
The mentioned test is performing the sfputil reset EthernetX for every interface on the SONiC switch, this action will flap the SFP device status (INSTERTED -> REMOVED -> INSTERTED).
The SONiC XCVRD daemon will catch this SFP device status change (because it is monitoring the presence status of the cable).
To judge the cable presence status, currently, we are still leveraging to read the first bytes of the EEPROM, and the EEPROM could be not ready at some moment and the SONiC XCVRD daemon will print the error log to Syslog:
ERR pmon#xcvrd: Error! Unable to read data for 'xx' port, page 'xx' offset 128, rc = 1, err msg: Sending access register

Before the "bad" PR, the message format is like this:

It was truncated by rsyslog because every message is the same. However, the "bad" PR introduces SFP index to the message:
