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

TCP/IP stack for Wabi 2.2

There is a stack already there that works for
some things, for example Eudora. I did not get
it to work for AOL30.

1. Packets from bottom of TCP/IP stack direct to application bypassing stack

Hello Everyone

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.
