netfilter: nfnetlink_queue: allow to attach expectations to conntracks
This patch adds the capability to attach expectations via nfnetlink_queue. This is required by conntrack helpers that trigger expectations based on the first packet seen like the TFTP and the DHCPv6 user-space helpers. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
