We (Stratum) are using this project through ONLP and encountered errors with some of our QSFP DACs. When parsing the EEPROM, we get this error message: 02-24 18:48:27.404405 [sff] sff_info_valid() failed: invalid module type, which seems to come from here: https://github.com/floodlight/bigcode/blob/master/modules/sff/module/src/sff.c#L732
02-24 18:48:27.404405 [sff] sff_info_valid() failed: invalid module type
Is this a driver issue or a non-compliant firmware? Other than that, the cable works fine.
Here is the EEPROM:

Picture of the DAC:
The issue was a faulty EEPROM. We re-flashed with correct values and now it works.
