  <li><b>HiFn 7751</b><br>
!     Cards using the 7751 can be used as a cryptographic accelerator (ie.
      <a href="http://www.powercrypt.com">PowerCrypt</a>).
      Current performance using a single Hifn 7751 on each end of a tunnel
      is 63Mbit/sec for 3DES/SHA1 ESP, nearly a 600% improvement over
      using a P3/550 cpu.  Further improvements are under way to resolve a
      few more issues, but as of April 13, 2000 the code is considered
!     stable.<p>
!     The 7751 is considered slow by industry standards and many vendors have
!     faster chips (even HiFn now has a faster but much more expensive chip).
!     We are already looking at supporting other chips such as
!     <a href="http://www.ire.com/OEM/OEMTechnologyDefault.htm">IRE 2141</a>,
!     <a href="http://www.bluesteelnet.com/product.html">Bluesteelnet 5501</a>,
!     <a href="http://www.pcc.pijnenburg.nl/pcc-ises.htm">Pijnenburg PCC-ISES</a>,
!     perhaps the
!     <a href="http://www.3com.com/promotions/3c990promo/index.html">3com 3c990</a>,
!     and others. IRE and Bluesteelnet in particular  have already been very
      friendly, and have given us all the information we need to support their
!     hardware.
      Intel (and 3com to a lesser degree) don't yet fully understand how
      they could benefit from giving us documentation for their cryptography
      cards, so feel free to contact them independently and encourage them.
