net: sfp: Add tx-fault workaround for Huawei MA5671A SFP ONT
[ Upstream commit 2069624dac19d62c558bb6468fe03678553ab01d ]
As noted elsewhere, various GPON SFP modules exhibit non-standard
TX-fault behaviour. In the tested case, the Huawei MA5671A, when used
in combination with a Marvell mv88e6085 switch, was found to
persistently assert TX-fault, resulting in the module being disabled.
This patch adds a quirk to ignore the SFP_F_TX_FAULT state, allowing the
module to function.
