Thank you for recommending using the show functions.

By using the rtems_bsdnet_show_inet_routes(), I found that the error I was
getting had to do with configuring the route table entry for the second
Ethernet device.  The way I had my device rtems_bsdnet_ifconfig structures
initialized, the code was trying to configure both Ethernet devices with
exactly the same route entry.

By changing the rtems_bsdnet_ifconfig structures for the Ethernet devices,
I was able to get the three ports initialized.  I still do not understand
why the RTEMS networking software creates the routing table entries it
does.

I will have to dig a little deeper into network routing in general to
understand what is going on.

Thanks again for your help.
