On a box with most of the optional Netfilter switches turned off some of the NLAs are never send, e. g. secmark, mark or the conntrack byte/packet counters. As a worst case scenario this may possibly still lead to ctnetlink skbs being reallocated in netlink_trim() later, loosing all the nice effects from the previous patches. I try to solve that (at least partly) by correctly #ifdef'ing the NLAs in the computation. Signed-off-by: Holger Eitzenberger <holger@eitzenberger.org>
