    sys/net              if.c if.h 
  Log:
  Re-add ifi_epoch, to struct if_data, this time replacing ifi_unused
  to avoid ABI changes.  It is set to the last time the interface
  counters were zeroed, currently the time if_attach() was called.  It is
  intentended to be a valid value for RFC2233's ifCounterDiscontinuityTime
  and to make it easier for applications to verify that the interface they
  find at a given index is the one that was there last time they looked.
  
  Due to space constraints ifi_epoch is a time_t rather then a struct
  timeval.  SNMP would prefer higher precision, but this unlikely to be
  useful in practice.
