Hi Russell,
GPON modules we are talking about are all ONT/ONU and all the ONT ONU
are configured by OLT unless you have a modded firmware.
ODI DFP-34X-2C2 is an ONT/ONU.
https://hack-gpon.org/ont-huawei-ma5671a/
https://hack-gpon.org/ont-fs-com-gpon-onu-stick-with-mac/
https://hack-gpon.org/ont-odi-realtek-dfp-34x-2c2/

I think the discussion on LAN_SDS_MODE=1 or LAN_SDS_MODE=6, started by
me is not part of the problem as the system after the quirk is working
at 2500-X with both settings. My fault!
The problem for these kind of modules is simply that they are not
showing up at 2500-X because EEPROM or Virtual EEPROM (in case of
MA5671A) failure to provide the correct speed to the linux driver.

Huawei MA5671A and Fiberstone GPON-ONU-34-20BI require:
"sfp_quirk_2500basex" and "sfp_fixup_ignore_tx_fault" quirks
ODI DFP-34X-2C2
only require "sfp_quirk_2500basex"

Hope this may help.

Regards
