Improve introductory XDP documentation with comprehensive getting started guide and enhanced API docs
This PR significantly improves the XDP for Windows documentation to make it more accessible to newcomers and provide better comparisons with Linux XDP.
Key Improvements
1. New Comprehensive Getting Started Guide (docs/getting-started.md)
- Prominent Linux XDP comparison: Added detailed side-by-side tables comparing features, differences, and architectural approaches
- Clear use cases: Documented when and why to use XDP for Windows
- Quick start instructions: Step-by-step setup and first program examples
- Architecture overview: Visual diagram showing the complete XDP stack
2. Enhanced AF_XDP Documentation (docs/afxdp.md)
- Removed placeholder TODOs: Replaced with comprehensive documentation
- Programming examples: Added code snippets for receiving and sending packets
- Performance guidance: Best practices for high-throughput applications
- Better sample references: Enhanced descriptions of available samples
3. Improved API Documentation
- Completed XDP_EXTENSION_INFO.md: Added detailed member descriptions and usage examples
- Removed placeholder content: Filled in previously empty sections with meaningful documentation
4. New Sample Application (samples/xdpcap/)
- Packet capture tool: Demonstrates traffic monitoring and analysis using AF_XDP
- Protocol parsing: Shows how to analyze Ethernet, IP, TCP, UDP, and ICMP packets
- Statistics collection: Example of gathering network traffic metrics
- Command-line interface: Professional sample with proper argument parsing
5. Updated Navigation
- Enhanced README: Added prominent link to new Getting Started guide
- Cross-references: Improved linking between related documentation sections
Impact
These changes address the three main requirements from the issue:
- ✅ General overview with Linux XDP comparison: Comprehensive comparison tables and architectural differences
- ✅ Improved API documents: Completed missing documentation and enhanced existing content
- ✅ More samples: Added xdpcap sample demonstrating a different use case (monitoring vs. forwarding)
The documentation is now much more approachable for developers new to XDP while maintaining the technical depth needed by experienced users.
Fixes #838.
