Description

Fix issues in cmis.get_transceiver_bulk_status

1. In case it fails to read EEPROM, either self.get_rx_power() or self.get_tx_power() can be a list of 'N/A'. Need to test it before calling self.mw_to_dbm otherwise exception TypeError("'<' not supported between instances of 'str' and 'int'") will be thrown.

   Exception occured at DomInfoUpdateTask thread due to TypeError("'<' not supported between instances of 'str' and 'int'")
   Traceback (most recent call last):

   Xcvrd: exception found at child thread DomInfoUpdateTask due to TypeError("'<' not supported between instances of 'str' and 'int'")
   

2. It should be a valid case for either self.get_rx_power() or self.get_tx_power() to return None. Handle other fields instead of returning None in this case

@prgeor could you please help review or assign someone?

[prgeor]

@stephenxs please provide more context in the description. What is failing? Which CLI? If the i2c read is failing then we should fix the optics or platform issue?
