| Description: The <bdf> is related the function for PF and VF. | |
| ZIP driver supports to configure each function's QoS, the driver | |
| supports to write <bdf> value to alg_qos in the host. Such as | |
| "echo <bdf> value > alg_qos". The qos value is 1~1000, means | |
| 1/1000~1000/1000 of total QoS. The driver reading alg_qos to | |
| get related QoS in the host and VM, Such as "cat alg_qos". | |
