* Name: net_foreachroute_ipv4 and net_foreachroute_ipv6
*
* Description:
* Traverse the routing table
*
* Input Parameters:
* handler - Will be called for each route in the routing table.
* arg - An arbitrary value that will be passed tot he handler.
*
* Returned Value:
* Zero (OK) returned if the entire table was search. A negated errno
* value will be returned in the event of a failure. Handlers may also
* terminate the search early with any non-zero, non-negative value.
