[Description]
Fix 1G/2.5G SFP IOT issues.
  - ADOP SFP-1GE-T-AD and SK-LiNK SFP-GE-T-100 1G RJ-45 SFP
    The Marvell 88E1111 of the SFP does not report speed capabilities
    from either BMSR or ESTATUS registers, utilize the feature callback
    function of the PHY drvier instead.
  - SK-LiNK SFP-GE-LX20-SM1310/SM1550-BIDI 1G Optical SFP
    The EEPROM checksum value of the SFP is incorrect, print
    warning messages to instead of returning error.
  - 10Gtek ASF-2G2-T and TL-SM410U 2.5G RJ-45 SFP
    The EEPROM of the SFP does not report speed capabilities, utilize
    the quirk_list to report its.
