TCP/IP between L4Linux and L4 task

Well, sounds good. So I'm currently trying to integrate the latest e1000
driver (v7.0.33) into ORe as my e1000 adapter is not supported by the
current one but encountered the following problem:

The updated driver wants to alloc some pages using alloc_page(). This
results in a undefined reference to "_alloc_pages" when linking ore:

I suppose I have to link something else? Any hints appreciated.

BTW is ORe an acronym for something? What does it stand for?
