ravb: Duplex handling update [PATCH/RFC 01/02] ravb: Do not announce 100Mbps HDX as supported [PATCH/RFC 02/02] ravb: Clean up duplex handling This series contains prototype-level code to update the Ethernet-AVB driver to improve duplex handling. Based on the latest data sheet for R-Car Gen3 [1] and R-Car Gen2 [2] the following information is part of the EthernetAVB-IF overview page: Transfer speed: Supports transfer at 100 and 1000 Mbps Mode: Full-duplex mode It seems that the driver implementation is not matching the information provided in the friendly data sheet, and on top of this during run-time when changing PHY configuration of the link partner the Ethernet-AVB PHY seems to want to announce unsupported modes. [1] R-Car Series, 3rd Generation Rev.1.00 (Apr 2018) [2] R-Car Series, 2nd Generation Rev.2.00 (Feb 2016) Not suitable for upstream merge yet - needs more discussion.
