This is _very_ interesting! From a first look OCF seems to be designed
for smartcards but acrypto seems to be the right pointer! It has support
for the hifn 7955 crypto accelerator chip which is assembled on the
Soekris VPN1401 PCI card. They talk about > 30 MByte/s (250 Mbit/s)
throughput. And this without overloading the CPU...
Has anyone some praxis experience with acrypto and dm-crypt? Stability,
data corruption (:)) and this sort of? There must be a cause it is not
in vanilla kernel.
