Use @s2 buffer to store string representation of tclass and get rid of extra SPRINT_BUF(): no need to preserve @s2 contents for later. Use print_string(PRINT_ANY, ...) with prepared by snprintf() string for both PRINT_JSON and PRINT_FP cases. While there use __u32 for flowinfo in link_gre6.c and check for IFLA_GRE_FLOWINFO attribute presense.
