net: sfp: add quirk for OEM 2.5G optical modules
Some OEM-branded SFP modules are incorrectly detected as
1000Base-X and fail to establish link on 2.5G-capable ports.
These modules do not properly advertise 2500Base-X capability
in their EEPROM and require forcing the correct SerDes mode.
Add sfp_quirk_2500basex for:
- OEM SFP-2.5G-LH03-B
- OEM SFP-2.5G-LH20-A
Both modules report:
Vendor name: OEM
Vendor PN: SFP-2.5G-LH03-B / SFP-2.5G-LH20-A
Tested on OpenWrt with successful 2.5G link establishment.
