Or is there handler somewhere else? No need to add handlers to nic_vf_cmd_msg_handler[]. It will run the path, if (i == ARRAY_SIZE(nic_vf_cmd_msg_handler)) err = hinic_msg_to_mgmt(&pfhwdev->pf_to_mgmt, HINIC_MOD_L2NIC, cmd, buf_in, in_size, buf_out, out_size, HINIC_MGMT_MSG_SYNC); right? or if not please show the related code.
