Detailed Description

Unit tests for PROFINET protocol wire-format structures.

Verifies serialization, parsing, fixed-size definitions, and selected protocol constants for the structures declared in protocol.h.

The tests cover:

• DCP header and block parsing/serialization.
• Ethernet header parsing and serialization.
• Fixed wire-format sizes of PROFINET packet structures.
• PROFINET DCE/RPC interface UUID generation.
• IP configuration decoding from DCP blocks.

Fixed-size checks are compared against the expected wire-format sizes established to help preserve binary compatibility with PROFINET devices.
