net: sfp: add quirk for 2.5G OEM BX SFP

Browse source

[ Upstream commit a850355610 ]

The OEM SFP-2.5G-BX10-D/U SFP module pair is meant to operate with
2500Base-X. However, in their EEPROM they incorrectly specify:
Transceiver codes   : 0x00 0x12 0x00 0x00 0x12 0x00 0x01 0x05 0x00
BR, Nominal         : 2500MBd

Use sfp_quirk_2500basex for this module to allow 2500Base-X mode anyway.
Tested on BananaPi R3.
