netfilter: xtables: add struct xt_mtchk_param::net
Some complex match modules (like xt_hashlimit/xt_recent) want netns information at constructor and destructor time. We propably can play games at match destruction time, because netns can be passed in object, but I think it's cleaner to explicitly pass netns. Add ->net, make sure it's set from ebtables/iptables/ip6tables code. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
