  Log:
  MFC the change of ifi_epoch to be uptime instead of wall clock time.
  The origional commit message follows:
  
          Change the definition of struct if_data's member ifi_epoch from
          wall clock time to uptime because wall clock time may go
          backwards.
  
          This is a change in the API which will impact SNMP agents who
          are using ifi_epoch to set RFC2233's ifCounterDiscontinuityTime.
          None are known to exist today.  This will not impact applications
          that are using the <index, epoch> tuple to verify interface
          uniqueness except that it eliminates a race which could lead to
          a false assumption of uniqueness.
