This set introduces the rate limiting feature to the Intel QAT accelerator. The Rate Limiting allows control of the rate of the requests that can be submitted on a ring pair (RP). This allows sharing a QAT device among multiple users while ensuring a guaranteed throughput. The first six commits address minor reworks and additions necessary for the feature's implementation. The subsequent patch introduces a mechanism for retrieving firmware feature capabilities. Patch nr 8 implements the core of the rate limiting. The final three commits add the required sysfs interface for configuring this newly introduced feature.
