net: sfp: add quirk for Lantech 8330-265D
[ Upstream commit 86a8e8e0ddbc3d14c799536eb888180b84d002f3 ]
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.
