+Subject: [PATCH] net: sfp: add quirk for Fiberstone GPON-ONU-34-20BI
+
+Fiberstone GPON-ONU-34-20B can operate at 2500base-X, but report 1.2GBd
+NRZ in their EEPROM.
+
+The module also require the ignore tx fault fixup similar to Huawei MA5671A
+as it gets disabled on error messages with serial redirection enabled.
