Sorry about that, I was paraphrasing the error, its coming from

cpukit/libnetworking/rtems/rtems_glue.c, line 867


Is there any documentation about where to find the list of drivers
already registered?  I'd guess its something related to that as the
error does not seem associated with the ip/netmask given for the
interface.
