Select this option if you want to use a PCI-attached cryptographic
adapter like the PCI Cryptographic Accelerator (PCICA) or the PCI
Cryptographic Coprocessor (PCICC). This option is also available
as a module called z90crypt.ko.

* Perform an RSA operation using a Modulus-Exponent pair
* This takes an ica_rsa_modexpo struct as its arg.
*
* NOTE: please refer to the comments preceding this structure
* for the implementation details for the contents of the
* block
*
* ICARSACRT
* Perform an RSA operation using a Chinese-Remainder Theorem key
* This takes an ica_rsa_modexpo_crt struct as its arg.
*
* NOTE: please refer to the comments preceding this structure
* for the implementation details for the contents of the
* block
*
* Z90STAT_TOTALCOUNT
* Return an integer count of all device types together.
*
* Z90STAT_PCICACOUNT
* Return an integer count of all PCICAs.
*
* Z90STAT_PCICCCOUNT
* Return an integer count of all PCICCs.
*
* Z90STAT_PCIXCCCOUNT
* Return an integer count of all PCIXCCs.
*
* Z90STAT_REQUESTQ_COUNT
* Return an integer count of the number of entries waiting to be
* sent to a device.
*
* Z90STAT_PENDINGQ_COUNT
* Return an integer count of the number of entries sent to a
* device awaiting the reply.
*
* Z90STAT_TOTALOPEN_COUNT
* Return an integer count of the number of open file handles.
*
* Z90STAT_DOMAIN_INDEX
* Return the integer value of the Cryptographic Domain.
*
* Z90STAT_STATUS_MASK
* Return an 64 element array of unsigned chars for the status of
* all devices.
* 0x01: PCICA
* 0x02: PCICC
* 0x03: PCIXCC
* 0x0d: device is disabled via the proc filesystem
*
* Z90STAT_QDEPTH_MASK
* Return an 64 element array of unsigned chars for the queue
* depth of all devices.
*
* Z90STAT_PERDEV_REQCNT
* Return an 64 element array of unsigned integers for the number
* of successfully completed requests per device since the device
* was detected and made available.
*
* ICAZ90STATUS (deprecated)
* Return some device driver status in a ica_z90_status struct
* This takes an ica_z90_status struct as its arg.
*
* NOTE: this ioctl() is deprecated, and has been replaced with
* single ioctl()s for each type of status being requested
*
* Z90QUIESCE (not recommended)
* Quiesce the driver. This is intended to stop all new
* requests from being processed. Its use is not recommended,
* except in circumstances where there is no other way to stop
* callers from accessing the driver. Its original use was to
* allow the driver to be "drained" of work in preparation for
* a system shutdown.
*
* NOTE: once issued, this ban on new work cannot be undone
* except by unloading and reloading the driver.
