net: sfp: add quirks for Hisense and HSGQ GPON ONT SFP modules
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 capable of 2500base-X (e.g. Banana Pi R3 / MT7986), the
kernel negotiates only 1G because it trusts the incorrect EEPROM data.
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.
