I would expect different layout in struct above.
#if defined(__LITTLE_ENDIAN_BITFIELD)
__u16 layer : 4, etype : 4, ecode : 8;
__u16 flag_m : 1, flag_d : 1, flag_r : 1, reserved : 13;
#elif defined(__BIG_ENDIAN_BITFIELD)
__u16 ecode : 8, etype : 4, layer : 4;
__u16 reserved : 13, flag_r : 1, flag_d : 1, flag_m : 1;
