net: sfp: add quirk enabling 2500Base-x for HG MXPD-483II
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. https://forum.banana-pi.org/t/bpi-r3-sfp-module-compatibility/14573/60 Reported-by: chowtom <chowtom@gmail.com> Tested-by: chowtom <chowtom@gmail.com> Signed-off-by: Daniel Golle <daniel@makrotopia.org> Reviewed-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk> Signed-off-by: David S.
