====================
net: phy: Add Open Alliance TC14 10Base-T1S PHY cable diagnostic support
This patch series adds Open Alliance TC14 (OATC14) 10BASE-T1S cable
diagnostic feature support to the Linux kernel PHY subsystem and enable
this feature for Microchip LAN867x Rev.D0 PHYs. 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.

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.
