Mohit Mehta wrote:
> iptc_zero_counter/ip6tc_zero_counter are functions available in libiptc to zero counters for a rule in a given chain. However, this is not exposed in iptables/ip6tables. The patch below exposes the underlying function to the user to zero out packet and byte counters for a specific rule.

Exposing this seems useful, the patch doesn't apply to the
current git version though:
