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".
