54 driver supports cards containing Broadcom and BlueSteel uBsec 5x0x
55 crypto accelerator chips.
59 driver registers itself to accelerate DES, Triple-DES, MD5-HMAC,

81 This extremely rare unit
82 was not very fast, lacked an RNG, and had a number of other bugs.
84 A faster and fixed version of the original, with a random number

87 A BCM5805 without public key engine or random number generator.
89 A slower version of the BCM5805.
91 Faster version of Bluesteel 5601.
93 64 bit version of the chip, and significantly more advanced.
95 Faster version of the BCM5820.
96 This is the chip found on the Sun Crypto Accelerator 1000.
