I have had a number of strange problems (including this one), when I
tried
to set both interfaces on the same subnet (eth0=192.168.2.50 and
eth1=192.168.2.51).
When I moved the second interface to the different subnet (192.168.3.51)
it 
worked. It still does :) It seems logical, since you usually don't need
two
interfaces on the same network, but still, the error report is
confusing.

Try to swap the order of interfaces in rtems_bsdnet_config structure. If
this is a 
problem, you should get the same message for the other interface.
