2-port inline network tester for CardputerZero (built-in LAN + one USB-LAN adapter).
- LOAD — traffic load-generator: one-way latency/loss/reorder/throughput + auto rate sweep (AF_PACKET).
- IMPAIR — transparent bridge + tc netem: delay/jitter/loss/dup/corrupt/reorder/rate-limit, CCTV-tuned presets.
Verified on the Mac emulator + arm64 container (48 host unit tests, real backends compile+link, non-root capability propagation validated). Not yet exercised on real NICs (hardware_verified=false) — honest-pending per the sibling apps.
Install: dpkg -i netsim_0.1.0_arm64.deb (postinst runs setcap cap_net_admin,cap_net_raw+eip). Needs iproute2, libcap2-bin.
