Module protocol 

Binary Protocol with CRC32 Checksums for Ghost-Link Discovery

This module implements a fixed-width binary protocol using:

• Fixed-size fields for zero-copy parsing
• CRC32 checksums for frame integrity (hardware-accelerated via crc32fast)
• Sequence numbers and versioning for ordering
• Zero-copy encoding with thread-local buffers

Structs

Enums

FrameKind

Frame kind enumeration

Constants

Ghost-Link EtherType (0x88B5)

MAX_FRAME_SIZE

Maximum frame size (header + max payload)

MAX_PAYLOAD_SIZE

Maximum payload size for discovery frames

PROTOCOL_VERSION

Protocol version

Functions
