ubsec -- Broadcom and BlueSteel uBsec 5x0x crypto accelerator
ubsec* at pci? dev ? function ?
The ubsec driver supports cards containing any of the following chips:
Bluesteel 5501 The original chipset, no longer made. This
extremely rare unit was not very fast, lacked an
RNG, and had a number of other bugs.
Broadcom BCM5801 A BCM5805 without public key engine or random
Broadcom BCM5802 A slower version of the BCM5805.
Broadcom BCM5805 Faster version of Bluesteel 5601.
Broadcom BCM5820 64 bit version of the chip, and significantly
Broadcom BCM5821 Faster version of the BCM5820. This is the chip
found on the Sun Crypto Accelerator 1000.
Broadcom BCM5822 Faster version of the BCM5820.
Broadcom BCM5823 Faster version of the BCM5822 that also supports
Broadcom BCM5825 Faster PCI Express or PCI-X version of the chip.
Broadcom BCM5860 IPSec/SSL Security Processor that is faster and
has more features.
Broadcom BCM5861 Faster version of the BCM5860.
Broadcom BCM5862 Faster version of the BCM5861.
The ubsec driver registers itself to accelerate DES, Triple-DES, MD5,
SHA1, MD5-HMAC, and SHA1-HMAC operations for opencrypto(9), and thus for
ipsec(4) and crypto(4). The driver also supports acceleration of AES-CBC
with the BCM5823 or newer.
On those models which contain a public key engine (almost all of the more
recent ones), this feature is registered with the crypto(4) subsystem.
On all models except the Bluesteel 5501 and Broadcom 5801, the driver
registers itself to provide random data to the rnd(4) subsystem.

The ubsec device driver appeared in OpenBSD 2.8. The ubsec device driver
was imported to FreeBSD 5.0, back-ported to FreeBSD 4.8, and subsequently
imported to NetBSD 2.0.
The BCM5801 and BCM5802 have not actually been tested.
