## Summary This patch adds `plcatool` app into netutils. It is a simple tool that allows configuration of the Physical Layer Collision Avoidance (PLCA) functionality in 10BASE-T1S PHYs. The syntax and behavior are very similar to `ethtool`'s PLCA options. The tool is compatible with PHYs that follow the [OA-TC14 specification](https://opensig.org/wp-content/uploads/2025/03/2024-12-10BASE-T1S-PLCA-Management-Registers-v1.4.pdf) defining the mapping of PLCA registers into MMD 31. ## Impact A new directory `plcatool` in `netutils` with application files is created. ## Testing The app was tested with Microchip LAN865x and Onsemi NCN7410 (NCN26010) MAC-PHYs on ESP32C6-devkitC, ESP32C6-devkitM and SAMV71-Xult boards. The behavior of coordinator (node-id 0) was verified on an oscilloscope by looking for transmitted beacon signal in expected intervals. Follower (node-id > 0) was verified by checking for '1' in PLCA status register when periodically receiving beacon and '0' otherwise. -- This is an automated message from the Apache Git Service.
