. UPDATING

sys/net if.c if.h
sys/sys param.h
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.
