Subject: netfilter: nf_conntrack: account packets drop by tcp_packet()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7d1e04598e5e92527840b6889fb75b4b30fdd33b;p=linux-beck.git

netfilter: nf_conntrack: account packets drop by tcp_packet()

Since tcp_packet() may return -NF_DROP in two situations, the
packet-drop stats must be increased.
