I add a few more debug outputs and now with this driver I can run a

$ nmap <ip>

from my host against the target and target's network stops always at the same 
point.

The last output from the driver is (with DEBUG macro defined):

net eth0: ievent: 08020000

and no further interrupt occurs anymore (I checked all three interrupt entry 
functions)

nmap on host's side outputs:

Starting Nmap 4.20 ( http://insecure.org ) at 2007-09-28 16:56 CEST
Interesting ports on 192.168.23.226:
Not shown: 852 filtered ports, 843 closed ports
PORT   STATE SERVICE
22/tcp open  ssh
23/tcp open  telnet

Nmap finished: 1 IP address (1 host up) scanned in 14.120 seconds

But I can't run it a second time, as the network on target's side doesn't 
respond. Any idea?
