- Implement BPF program for TC ingress using dynptrs to safely parse packet headers and manage variable-length ringbuf records.
- Create user-space loader for the BPF program, allowing configuration of blocked ports and snapshot lengths for TCP payloads.
- Define necessary data structures and constants in header file for both BPF and user-space contexts.
- Add a comprehensive test script to validate functionality, including basic packet capture and port blocking tests.
