From: Jozsef Kadlecsik <kadlec@xxxxxxxxxxxxx>
The commit 510841da1fcc ("netfilter: ipset: enforce documented limit to
prevent allocating huge memory") was too strict and prevented to add up to
64 clashing elements to a hash:net,iface type of set. This patch fixes the
issue and now the type behaves as documented.
