+       Counters are stored in the lease storage and after schema
+       upgrade all existing leases are considered to be part of pool
+       ID 0. On lease update, the counters will be updated accordingly
+       including pool IDs and statistics will converge to real values
+       over time.

 2142.  [func]          piotrek
        New command option was added to perfdhcp: --or.
        It allows to insert extra option(s) to relayed DHCPv6 message
