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.

Ciunas Bennett (3):
  crypto: qat - add rate limiting sysfs interface
  crypto: qat - add rp2svc sysfs attribute
  crypto: qat - add num_rps sysfs attribute

Damian Muszynski (4):
  units: Add BYTES_PER_*BIT
  crypto: qat - add bits.h to icp_qat_hw.h
  crypto: qat - add retrieval of fw capabilities
  crypto: qat - add rate limiting feature to qat_4xxx

Giovanni Cabiddu (4):
  crypto: qat - refactor fw config related functions
  crypto: qat - use masks for AE groups
  crypto: qat - fix ring to service map for QAT GEN4
  crypto: qat - move admin api
