[ Upstream commit 6a66ce44a51bdfc47721f0c591137df2d4b21247 ]
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.
