A bug fix to Mellanox drivers:
Prevent reading unsupported slave address from SFP EEPROM
by testing Diagnostic Monitoring Type byte in EEPROM.
If some SFP transceiver doesn't support Digital Optical Monitoring (DOM),
thus reading SFP EEPROM slave address 0x51 could return an error.
Add code to detect the availability of DOM support,
it is verified by reading from zero page Diagnostic Monitoring Type byte
describing how diagnostic monitoring is implemented by the transceiver.
