The Hifn 9751 shares the same PCI ID.
This chip is basically a 7751, but with the cryptographic functions missing.
Instead, the 9751 is only capable of doing compression.
Since we do not currently attempt to use any of these chips to do
compression, the 9751-based cards are not useful.
Support for the 7955 and 7956 is incomplete; the asymmetric crypto
facilities are to be added and the performance is suboptimal.

The 7751 chip starts out at initialization by only supporting compression.
A proprietary algorithm, which has been reverse engineered, is required to
unlock the cryptographic functionality of the chip.
It is possible for vendors to make boards which have a lock ID not known
to the driver, but all vendors currently just use the obvious ID which is
13 bytes of 0.
