[PATCH net-next] net: sfp: add quirk for Lantech 8330-265D

[Marek Behún]

Similar to Lantech 8330-262D-E, the Lantech 8330-265D also reports
2500MBd instead of 3125MBd.

Also, all 8330-265D report normal RX_LOS in EEPROM, but some signal
inverted RX_LOS. We therefore need to ignore RX_LOS on these modules.
