Thanks, will fix that in both patches in v2.

Thanks for the comment.  And yes, I think currently, iptables’s
connlimit extension does support limiting the # of connections.  Users
need to configure the zone properly, and the iptable’s connlimit
extension is using netfilter's nf_conncount backend already.

The main goal for this patch is to utilize netfilter backend
(nf_conncount) to count and limit the number of connections. OVS needs
the proposed OVS_CT_LIMIT netlink API and the corresponding booking
data structure because the current nf_conncount backend only counts
the # of connections, but it does not keep track of the connection
limit in nf_conncount.
