Detailed Description

Tests for the common EthernetPacketBackend implementation.

Covers validation, Ethernet EtherType matching, VLAN-aware filtering, frame-size validation, and receive timeout behavior. Tests which exercise libpcap access require PROFINET_TEST_INTERFACE to select an Ethernet device.
