automated: linux: add tcpreplay testing framework This patch introduces an automated testing setup for tcpreplay-based traffic replay and analysis. The system consists of: 1. `tcpreplay.py`: A test runner that: - Creates and configures a TAP interface - Replays PCAP files using `tcpreplay` - Tracks results and produces a summary for each test - Handles both expected and unexpected results (e.g., xfail -> pass) 2. `generate_pcap.py`: A Scapy-based script to: - Generate a suite of PCAP files for functional and edge case testing - Include both valid packets and malformed/false-positive scenarios - Provide coverage for multiple protocols (TCP, UDP, ICMP, DNS, etc.) - Simulate problematic flows like fragmented packets and invalid flags Highlights: - xfail support: tests expected to fail are counted as 'pass' if they do fail - xpass detection: alerts if a known-broken test unexpectedly succeeds - Easy extensibility for new PCAPs and expectations Example test cases include: - TCP lifecycle (`tcp_basic`, `tcp_full_cycle`) - Bad flag scenarios (`bad_tcp_flags`) - Noise/overlap (`false_positive_overlap`) - Fragmentation and malformed headers Signed-off-by: Anders Roxell <anders.roxell@linaro.org>
