I found it under
http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=17182

That driver was never submitted for inclusion anywhere, so it is not
really relevant here. The APIs are similar, but not identical, most
importantly they use a different ioctl command base number, but also
some of the structures are laid out slightly differently.

Ohtake-san, Richard's code already contains an abstraction for multiple
ieee1588 sources, which looks like it should perfectly fit your purposes.
I don't see room for another user interface, so please try to integrate
into version 5 of his ptp code.
