Subject: [PATCH 15/33] netfilter: ipset: Move extension data to set structure
From: Jozsef Kadlecsik <kadlec@...ckhole.kfki.hu>
Default timeout and extension offsets are moved to struct set, because
all set types supports all extensions and it makes possible to generalize
extension support.
Signed-off-by: Jozsef Kadlecsik <kadlec@...ckhole.kfki.hu>
