Under Wabi 2.2 is it possible to install some kind of TCP/IP stack.

I am working on a ADSL modem and have the following situation that I
would like to have some advice on.
I need to filter out some packages in the lower level of the network
stack. There are 2 types of packages: [eth | ppp | ip | udp] and [eth
| ip | udp], the data in these packages are the same and they can be
identified with the first 16 bits in the UDP data.
I have manage to catch these packages in the /net/core/dev.c file and
function netif_rx(...) with the 16 bit ID so I have the packages.
Now for my question: How do I in an easy way get these packages
directly to my application without using the network stack. I need
BOTH of these packages to reach there and if I use socket the one with
PPP get thrown away somewhere and that is not so good.
I know this is not a very specific question and a little vague but
some advice and pointers would be appreciated.
