Research direction
Start by locating RT-Thread's current lwIP 2.1.2 component integration and its build configuration, then review the upstream lwIP 2.2.1 changes and compatibility requirements. The work is done when the component uses version 2.2.1, builds through the relevant RT-Thread targets, and existing networking tests or checks pass.
