So the SDK for the Hifn HIPP devices is 2.4 only, thats seems a bit
dodgy.

I checked my hifn extranet login and couldn't find anything better than
their old 795x source.

You could try contacting Hank Cohen at hifn, he has helped me in the
past.  Maybe they have something better.

Let him know you were talking to me about OCF/HIFN/8155 and were
wondering if they had anything for linux-2.6 in that space.

Of course the SDK is more than likely 95% OS independant for use with
vxworks/windows/whatever,  so you may be able to use it on almost any OS
without too much work :-(

Cheers,
