How to offload htb on bf2

I’m doing network configuration on bf2 now. I updated my kernel version (5.15) and installed the NIC driver(mlnx_ofed) as required by the documentation. when i want to use the tc qdisc add dev XX root htb offload command to offload to bf2(this parameter is mentioned in the man htb), but the actual application of the tc command does not support the offload parameter(RTNETLINK answers: Operation not supported).
