 * Name: net_foreachroute_ipv4 and net_foreachroute_ipv6
 *
 * Description:
 *   Traverse the routing table
 *
 * 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
