zephyr-netbuf

What problem does it solve?

Facilitates comprehensive understanding and effective utilization of Zephyr's net_buf memory management library to optimize networking, Bluetooth, and USB data handling.

Core Features & Use Cases

• Pool Management: Guides creation and configuration of buffer pools with fixed or variable sizes for different application scenarios.
• Buffer Lifecycle: Details allocation, reference counting, resetting, and freeing of net_buf structures to ensure proper memory management.
• Data Operations: Explains methods for adding, removing, pushing, and pulling data within buffers, handling endian conversions, and managing fragment chains.
• Fragmentation Handling: Covers chain creation, traversal, linearization, and chain manipulation for large or segmented packets.
• Application Examples: Demonstrates constructing network packets, reassembling received fragments, and protocol parsing strategies.
