Hardware: Dell PowerEdge R300 with:

-- Intel Xeon E3110 - dual-core, 3.0GHz
-- 4GB memory (3326MB visible to the non-PAE kernel)
-- PCI-X riser card
-- Broadcom BCM95821SSN PCI-X cryptographic accelerator card

Kernel modules: cryptodev, ubsec

>Description:
When cryptodev is present, OpenSSL probes its usability but actually never
uses it for cryptographic operation, falling back to the default,
software-based implementation.
>How-To-Repeat:
With ubsec.ko and cryptodev.ko loaded:

$ ktrace openssl speed -evp des-cbc -elapsed
$ kdump | grep ioctl

The last command shows no CIOCCRYPT ioctls, i.e. actual hardware encryptions.

This problem is a regression, previously unobserved on FreeBSD 6.4 (which
however has its own problem; see kern/133143).
