how to Add a route to a host in RTEMS ?

[Thomas Doerfler]

Hi,

I am not an expert in setting routing options, but maybe you 
might have a look into the "bootp_subr.c" file (in 
c/src/libnetworking/nfs or cpukit/libnetworking/nfs, depending 
on the rtems version you are working with). In this file, the 
routing table is modified in various ways, maybe you might use 
it as a starting point?

wkr,
	Thomas.
