Subject: [PATCH AUTOSEL 6.6 12/31] net: sfp: add quirk for Fiberstone GPON-ONU-34-20BI

From: Christian Marangi <ansuelsmth@...il.com>

[ Upstream commit d387e34fec407f881fdf165b5d7ec128ebff362f ]

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.
