commit f54e9367f8499a9bf6b2afbc0dce63e1d53c525a
Author: Alexey Dobriyan <adobriyan@gmail.com>
Date: Mon Jan 18 08:25:47 2010 +0100

netfilter: xtables: add struct xt_mtdtor_param::net

Add ->net to match destructor list like ->net in constructor list.

Make sure it's set in ebtables/iptables/ip6tables, this requires to
propagate netns up to *_unregister_table().
