Add a compat wrapper to make modules work with older Linux.

Browse Source 
The extension modules use the API of a fairly recent kernel, if not
even the networking git tree. To make it work with older Linux
kernels, an API wrapper is added. Should compile against
running-kernels Linux 2.6.19..current (tested: 2.6.22..current).
