To clarify how table expiration works: we do not install an
individual timer for every table entry; that would way too many.
Instead, every table gets *one* timer which periodically triggers
the expiration of all outdated entries. By default, this is done
every 10s (table_expire_interval). Furthermore, when entries are
expired, only 5000 (table_incremental_step) are expired in a row,
then a delay of 0.01 (table_expire_delay) is inserted to avoid
dropping packets.
