Yes. > But you are definitely right - looks like enabled internal bridge. Where > I can look for parameters which control such behaivor? Did you add "options BRIDGE" to your kernel config file? I'm now somewhat confused. I *think* that you'd normally shouldn't see this message, unless you enabled bridging. However, why would you want to enable bridging between two interfaces connected to the same net? Why have you connected both interfaces to the same net? If you want your host to be on two subnets on the same wire, simply configure both IPs (see /etc/rc.conf for details). >> The non-working autoselect might be due to different PHY chips used >> (jugding from the vastly different MAC addresses, I guess the cards are >> from two diffent vendors).

Can you compile /sys/pci/if_de.c with TULIP_DEBUG enabled? And give us some more information on the make and model of the cards your using?
