  47. * Name: net_foreachroute_ipv4 and net_foreachroute_ipv6
  48. *
  49. * Description:
  50. * Traverse the routing table
  51. *
  52. * Input Parameters:
  53. * handler - Will be called for each route in the routing table.
  54. * arg - An arbitrary value that will be passed tot he handler.
  55. *
  56. * Returned Value:
  57. * Zero (OK) returned if the entire table was search. A negated errno
  58. * value will be returned in the event of a failure. Handlers may also
  59. * terminate the search early with any non-zero, non-negative value.
