Several GPON ONT SFP sticks based on Realtek RTL960x report 1000BASE-LX at 1300MBd in their EEPROM but can operate at 2500base-X. On hosts with serdes fixed at 2.5Gbase-X (e.g. Banana Pi R3 / MT7986), the kernel rejects them with 'no common interface modes'. Add quirks for: - Hisense-Leox LXT-010S-H - Hisense ZNID-GPON-2311NA - HSGQ HSGQ-XPON-Stick Each quirk advertises 2500base-X and ignores TX_FAULT during the module's ~40s Linux boot time. Tested on Banana Pi R3 (MT7986) with OpenWrt 25.12.1, confirmed 2.5Gbps link and full throughput with flow offloading.
