It's the complete ixp400 access library. The file available via the link above is called "IPL_ixp400AccessLibrary-2_0.zip" and the BSD version of it is called "BSD_ixp400AccessLibrary-2_0.zip". Only the license headers seem to be replaced. As I heard the 2.1 version should also be available in the BSD version in december, but I didn't get access to it until now.
