Subject: [PATCH net-next] net: sfp: add quirk for OEM DFP-34X-2C2 GPON ONU SFP DFP-34X-2C2 is a GPON spf module working at both1000baseX and 2500baseX. Setting the module to LAN_SDS_MODE=6 the module is working at 2500baseX with auto negotiation see at https://hack-gpon.org/ont-odi-realtek-dfp-34x-2c2/ Unfortunatly the module's PHY is accessible at 1000baseX only. ethtool returning: Supported ports: [Fibre ] Supported link modes: 1000baseX/Full

After applying the quirk:
Supported ports: [ Fibre ]
Supported link modes: 1000baseX/Full
2500baseX/Full
Tested on BANANA PI R3 in OpenWRT v 23.05.2 Kernel 5.15.137
Tested on sfp to ethernet Media Converter.
Autonegotiating 10001000baseX or 2500baseX according to the connected
host speed.

This module is existing in 2 versions:
Vendor = "ODI"
Vendor = "OEM"
This is the patch for vendor "OEM"

Patch has been inserted keeping the list in alphabetical order
first by vendor first and then by part string.

Your subject line is way too long. Didn't look further because that
makes it difficult to read.

Please wait at least 24 hours for other review comments before
re-posting. Thanks.
