These modules do not properly advertise 2500Base-X capability in their EEPROM and require forcing the correct SerDes mode. Add sfp_quirk_2500basex for: - OEM SFP-2.5G-LH03-B - OEM SFP-2.5G-LH20-A Both modules report: Vendor name: OEM Vendor PN: SFP-2.5G-LH03-B / SFP-2.5G-LH20-A Tested on OpenWrt with successful 2.5G link establishment.
