19 Contact: linux-crypto@vger.kernel.org
20 Description: The <bdf> is related the function for PF and VF.
21 SEC driver supports to configure each function's QoS, the driver

24 1/1000~1000/1000 of total QoS. The driver reading alg_qos to
25 get related QoS in the host and VM, Such as "cat alg_qos".
