Hey, has anyone got the ClearFog (ARMADA 388 SoC) to work with the
MA5671A? I've to been trying to get the ClearFog to read the MA5671A's
EEPROM however it always throws the following error:
> # dmesg | grep sfp
> [ 4.550651] sfp sfp: Host maximum power 2.0W
> [ 5.875047] sfp sfp: please wait, module slow to respond
> [ 61.295045] sfp sfp: failed to read EEPROM: -6
I've tried to increase the retry timeout in `/drivers/net/phy/sfp.c`
(i.e. T_PROBE_RETRY_SLOW) so far, any suggestions would be appreciated.
Also, I'm on kernel version 5.9.13.

The MA5671A modules are configured to use dying gasp on pin 7, and pin 7 is grounded on the Armada 388 Clearfog platforms, resulting in the module not booting. I'm sorry, I can't recommend a module; I don't use SFP GPON modules myself.
