PPP Code was updated
ZeroCopy Stuff was added
Netfilter Code changed

Current Status AFAIK:

- PPPOE Code was not changed until 2.4.7 (when they started tracking down
our problem)
- Netfilter Code (concerning our issue) was already revisited by Rusty
Russel, but no potential problems were found
- what about the ppp_generic and ppp_synctty stuff ? (Holger reports having
similar problems with ISDN, we use this there too, right?)
