Subject: Re: [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

makes it difficult to read.

Please wait at least 24 hours for other review comments before
