[ Upstream commit a85035561025063125f81090e4f2bd65da368c83 ]
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.
