[NETFILTER]: ctnetlink: rework conntrack fields dumping logic on events
| NEW | UPDATE | DESTROY | ----------------------------------------| tuples | Y | Y | Y | status | Y | Y | N | timeout | Y | Y | N | protoinfo | S | S | N | helper | S | S | N | mark | S | S | N | counters | F | F | Y | Leyend: Y: yes N: no S: iif the field is set F: iif overflow This patch also replace IPCT_HELPINFO by IPCT_HELPER since we want to track the helper assignation process, not the changes in the private information held by the helper.
