[Macchiato] macchiatobin problem

[alpha_one_x86]

Dear Baruch Siach,

*Your patch worked, some body can push it in upstream?*

I remain blocked on:

ethtool -m eth3
Cannot get module EEPROM information: Operation not supported

[   22.265548] mvpp2 f4000000.ethernet eth3: configuring for
inband/2500base-x link mode
[   22.266897] IPv6: ADDRCONF(NETDEV_UP): eth3: link is not ready

I try do work:

https://www.fs.com/products/48929.html Cisco GLC-LH-SM-20 Compatible
1000BASE-LX/LH SFP 1310nm 20km DOM Transceiver Module

But failed, maybe not dynamically down to 1G.

Cheers,
