[PATCH nf] netfilter: nf_tables: do not dump chain counters if not enabled

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Chain counters are only enabled on demand since 9f08ea848117, skip them
when dumping them via netlink.

Fixes: 9f08ea848117 ("netfilter: nf_tables: keep chain counters away from hot path")
