Detailed Description

Unit tests for PROFINET Ethernet VLAN-tag detection.

Verifies that the Ethernet parser correctly determines the location of the EtherType when Ethernet frames are untagged, 802.1Q tagged, or QinQ double-tagged.

PROFINET RT and RTA traffic may be received with priority VLAN tags. Therefore protocol parsing must not assume that the EtherType always starts at Ethernet byte offset 12.
