87 - A pkey base and API kernel module (pkey.ko) which offers the
88 infrastructure for the pkey handler kernel modules, the ioctl
89 and the sysfs API and the in-kernel API to the crypto cipher
90 implementations using protected key.
91 - A pkey pckmo kernel module (pkey-pckmo.ko) which is automatically
92 loaded when pckmo support (that is generation of protected keys
93 from clear key values) is available.

597 The QCE engine does not appear to scale as well as the CPU to handle
598 multiple crypto requests. While the ipq40xx chips have 4-core CPUs, the
599 QCE handles only 2 requests in parallel.
600
601 Ipsec throughput seems to improve when disabling either family of
602 algorithms, sharing the load with the CPU. Enabling skciphers-only
603 appears to work best.

649 help
650 This sets the default maximum request size to perform AES requests
651 using software instead of the crypto engine. It can be changed by
652 setting the aes_sw_max_len parameter.
653
654 Small blocks are processed faster in software than hardware.
655 Considering the 256-bit ciphers, software is 2-3 times faster than
656 qce at 256-bytes, 30% faster at 512, and about even at 768-bytes.
657 With 128-bit keys, the break-even point would be around 1024-bytes.
658
659 The default is set a little lower, to 512 bytes, to balance the
660 cost in CPU usage. The minimum recommended setting is 16-bytes
661 (1 AES block), since AES-GCM will fail if you set it lower.
662 Setting this to zero will send all requests to the hardware.
663
664 Note that 192-bit keys are not supported by the hardware and are
665 always processed by the software fallback, and all DES requests
666 are done by the hardware.
