There is no "low effort" way. Look at:
include/uapi/linux/rtnetlink.h
/*****************************************************************
* Traffic control messages.
****/
struct tcmsg {
unsigned char tcm_family;
unsigned char tcm__pad1;
unsigned short tcm__pad2;
int tcm_ifindex;
__u32 tcm_handle
__u32 tcm_parent;
__u32 tcm_info;
};
The handles are 32 bits. with Major/minor of 16 bit.
