[NETFILTER] NAT sequence adjustment: Save eight bytes per conntrack
This patch reduces the size of 'struct ip_conntrack' on systems with NAT by eight bytes. The sequence number delta values can be int16_t, since we only support one sequence number modification per window anyway, and one such modification is not going to exceed 32kB ;) Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S.
