Subject: [PATCH 1/2] netfilter: ipset: bitmap:ip,mac: fix listing with timeout

From: Jozsef Kadlecsik <kadlec@...ckhole.kfki.hu>

The type when timeout support was enabled, could not list all elements,
just the first ones which could fit into one netlink message: it just
did not continue listing after the first message.
