[NETFILTER]: x_tables: add connlimit match
ipt_connlimit has been sitting in POM-NG for a long time.
Here is a new shiny xt_connlimit with:
* xtables'ified
* will request the layer3 module
(previously it hotdropped every packet when it was not loaded)
* fixed: there was a deadlock in case of an OOM condition
* support for any layer4 protocol (e.g. UDP/SCTP)
* using jhash, as suggested by Eric Dumazet
* ipv6 support
