The HG MXPD-483II 1310nm SFP module is meant to operate with 2500Base-X,
however, in their EEPROM they incorrectly specify:
Transceiver type : Ethernet: 1000BASE-LX
...
BR, Nominal : 2600MBd
Use sfp_quirk_2500basex for this module to allow 2500Base-X mode anyway.

Please could you also arrange for the reporter to capture the ethtool
information via:
ethtool -m ethX raw on > sfp-name.bin
and send me the binary file?
Thanks!
