This option allows to choose whether to build support for all algorithms

The QCE engine does not appear to scale as well as the CPU to handle

multiple crypto requests. While the ipq40xx chips have 4-core CPUs, the

QCE handles only 2 requests in parallel.

Ipsec throughput seems to improve when disabling either family of

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