…#17365) - Why I did it Mellanox MSN2410 platforms have a non-functional error log: "ERR pmon#sensord: Error getting sensor data: dps460/#10: Can't read". This error is because of a firmware issue with some PSU, we are not able to upgrade the FW online. Since there is no functional impact, this error log can be ignored safely - How I did it Add a new rsyslog rule to the rsyslog-container.conf.j2, if the docker name is pmon and the platform name matches, the new rule will be inserted into the docker rsyslogd.conf - How to verify it run regression on the MSN2410 platform to make the error log will not be printed to the syslog.

Why I did it
fix low polarity wrong value for hw_reset deassert as part of power_on_module state function
fix power_good sysfs that returns empty string upon cable plug out
Work item tracking
How I did it
send 1 to hw_reset sysfs instead of existing 0 value sent to deassert hw_reset after power_on when needed
move seek(0) of sysfs fd before reading the sysfs fd
How to verify it
run the code in manual test of plugged out cable when the switch it booted.
then plug in the cable after module detection is done and dynamic detection takes place listening to sysfs changes via poller
for optic CMIS cable CMIS it will not be powered on thus will go into power_on_module function with the above change here.
at the end of module detection for this new cable inserted, EEPROM should be available for reading (currently with 0 sent to hw_reset EEPROM is not available at the end)
make sure power_good sysfs is not empty anymore upon cable plug out - it should have value of 0 when the cable is out
Which release branch to backport (provide reason below if selected)
Tested branch (Please provide the tested image version)
