Research direction
Study existing implementations of similar ioctls in gVisor's syscall handling code (e.g., pkg/sentry/syscalls/linux). Implement handlers for SIOCGIFMAP, SIOCGIFTXQLEN, SIOCGIFDSTADDR, SIOCGIFBRDADDR. Ensure the handlers interact correctly with gVisor's network stack. Test with appropriate tools.
