These patches provide standardized cable test functionality for 10BASE-T1S Ethernet PHYs, allowing users to perform cable diagnostics via ethtool. Patch Summary: 1. add OATC14 10BASE-T1S PHY cable diagnostic support - Implements support for the OATC14 cable diagnostic feature in Clause 45 PHYs. - Adds functions to start a cable test and retrieve its status, mapping hardware results to ethtool codes. - Exports these functions for use by PHY drivers. - Open Alliance TC14 10BASE-T1S Advanced Diagnostic PHY Features. https://opensig.org/wp-content/uploads/2025/06/OPEN_Alliance_10BASE-T1S_Advanced_PHY_features_for-automotive_Ethernet_V2.1b.pdf 2. add cable diagnostic support for LAN867x Rev.D0 - Integrates the generic OATC14 cable test functions into the Microchip LAN867x Rev.D0 PHY driver. - Enables ethtool cable diagnostics for this PHY, improving troubleshooting and maintenance. ==================== Link: https://patch.msgid.link/20251105051213.50443-1-parthiban.veerasooran@microchip.com Signed-off-by: Jakub Kicinski --- ac81130e3607a2c34a6fb20a8da9ace0c09ed6ff
