Stmmac refers to the Linux kernel driver for STMicroelectronics Ethernet MACs, enabling hardware timestamping (PTP) on supported devices.
Overview
Stmmac refers to the Linux kernel driver for STMicroelectronics Ethernet MACs, enabling hardware timestamping (PTP) on supported devices. It is significant in cybersecurity due to its role in precise time synchronization and network logging; a misconfiguration in its PTP pathway can affect timing accuracy and system stability on affected systems.
