+Subject: [PATCH] net: sfp: add quirk for ZOERAX SFP-2.5G-T
+
+This is a 2.5G copper module which appears to be based on a Motorcomm
+YT8821 PHY. There doesn't seem to be a usable way to to access the PHY
+(I2C address 0x56 provides only read-only C22 access, and Rollball is
+also not working).
+
+The module does not report the correct extended compliance code for
+2.5GBase-T, and instead claims to support SONET OC-48 and Fibre Channel:
+
+ Identifier : 0x03 (SFP)
+ Extended identifier : 0x04 (GBIC/SFP defined by 2-wire interface ID)
+ Connector : 0x07 (LC)
+ Transceiver codes : 0x00 0x01 0x00 0x00 0x40 0x40 0x04 0x00 0x00
+ Transceiver type : FC: Multimode, 50um (M5)
+ Encoding : 0x05 (SONET Scrambled)
+ BR Nominal : 2500MBd
+
+Despite this, the kernel still enables the correct 2500Base-X interface
+mode. However, for the module to actually work, it is also necessary to
+disable inband auto-negotiation.
+
+Enable the existing "sfp_quirk_oem_2_5g" for this module, which handles
+that and also sets the bit for 2500Base-T link mode.

+Subject: [PATCH] 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.
