and BlueSteel uBsec 5x0x crypto accelerator
ubsec* at pci?
ubsec driver supports cards containing
any of the following chips:
ubsec driver registers itself to
accelerate Triple-DES, MD5-HMAC, and SHA1-HMAC operations for
ipsec(4). The driver also supports
acceleration of AES-CBC with the BCM5823 or newer.
On all models except the Bluesteel 5501 and Broadcom 5801, the driver registers itself to provide random data to the random(4) subsystem.

The BCM5801 and BCM5802 have not actually been tested. Also, some of the newer chips support AES-CTR (AES Counter Mode) but it is not supported by the driver. The advanced SSL/TLS acceleration features of the BCM5860 or newer are not supported by the driver.
