Summary for 2026-05: Delivered MAVLink Network Interface Binding for SITL in PX4-Autopilot, enabling binding of MAVLink connections to a specific network interface via the PX4_NET_INTERFACE environment variable. This change improves simulation flexibility and reproducibility, and directly supports diverse networking configurations in CI and development environments. Implemented in commit a5549b5c753a57664b36f17e350ad35379947b5b (feat(simulation): Bind Mavlink to specific interface via PX4_NET_INTERFACE, #26385), which also fixes issue #26384. Updated SITL documentation to add a dedicated Environment Configuration subsection for PX4_NET_INTERFACE and consolidated related content. Overall impact includes enhanced test stability, easier debugging of network setups, and stronger collaboration across teams. Technologies/skills demonstrated include environment-variable driven configuration, MAVLink networking, SITL experimentation, and documentation collaboration.
