I switched off auto negotiation on the NUT (Linux 2.6.15usagi with 
Davicom DM9xxx driver), but unfortunately the behaviour did not change. 
What else can I do? It seems that the unit is not sending DAD packets at 
all (checked with tcpdump), maybe there is something I can change in the 
kernel to initiate DAD manually after I loaded the network driver module?

Kind regards,
Heiko
