RTEMS BOOTP and Linksys routers

The Linksys router will not issue infinite leases. If one would add dhcp
renew features to the current networking code where would one begin?

Our experience is that some routers do not support bootp or bootp 
needs to be enabled.  We wound up using umon to DHCP for an address 
which we then call from RTEMS to get the IP address.
