It's userspace which is managing the entries in the kernel hash table and it has some intelligence about aging out entries (and specifically about doing it more aggressively as the number of entries increases), so it's not really unbounded. In practice, userspace actually keeps the number of entries much smaller than the maximum size of the table. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
