netfilter: conntrack: add nf_ct_iter_data object for nf_ct_iterate_cleanup*()
This patch adds a structure to collect all the context data that is passed to the cleanup iterator. struct nf_ct_iter_data { struct net *net; void *data; u32 portid; int report; }; There is a netns field that allows to clean up conntrack entries specifically owned by the specified netns.
