Forget this, this can happen in an attempt to reopen a closed
connection, and such case is likely. We need such ID in order to achieve
accuracy. I think that it must be the user who has to choose if he wants
accuracy or not, in such case we have to provide the corresponding
methods to achieve it. A user could kill a conntrack by means of:
a) the tuples, if he doesn't want accuracy
b) the tuples + the id, if he does.
