If you've never worked with kernel code before, it's extremely difficult.  I 
highly recommend that you get involved with development of existing kernel 
networking code before you try to make this leap.

There are a few O'Reilly books about the kernel networking stack, and anything 
written in the past few years should be recent enough for your purposes.  It 
would probably also be helpful to read articles (such as those on lwn.net) about 
new network stack features that have been added.  The commentary there will give 
you a general idea of the challenges you'll face, but you'll need to complement 
that with experience working with the network code.
