   4 Subject: [PATCH] net: sfp: add quirk for Fiberstone GPON-ONU-34-20BI
   5
   6 Fiberstone GPON-ONU-34-20B can operate at 2500base-X, but report 1.2GBd
   7 NRZ in their EEPROM.

   9 The module also require the ignore tx fault fixup similar to Huawei MA5671A
  10 as it gets disabled on error messages with serial redirection enabled.
