Detailed Description

Tests for the Asio-backed Linux raw Ethernet socket.

These tests exercise socket creation, interface validation, timeout handling, and asynchronous send operations. The tests use the Linux loopback interface so they do not depend on a physical PROFINET device.

Creating an AF_PACKET socket requires CAP_NET_RAW.
