Ethernet bridge generates unwanted screen output, why?

[christian funk <c.funk@zweitform.de>]

I just finished building my beautiful bridge firewall, and it _seems_ 
to work perfectly!

However, always after "up"ing the bridge with ifconfig I get massive 
amounts of screen output to EVERY local tty, thus disrupting my local 
command line interface.

This output starts by telling my that the interfaces are in leaning 
mode and then goes on for ever with stuff like:

skb: pf=2 (unowned) dev=eth1 len=40
PORTO=6 xxx.xxx.xxx.xxx:53746 xxx.xxx.xxx.yyy:110 L=40 S=0x00 I=47345 
F=0x40000 T=64
nf_hook: hook 4 already set.


Anybody know why, and/or how I can stop the output at least until I get 
right what's still wrong?
