Subject: netfilter: nf_nat_snmp_basic: replace ctinfo with dir.
X-Git-Tag: v5.15~9522^2~108^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8b8f0813b763efb55a8462dab096868a6bafd1ba;p=platform%2Fkernel%2Flinux-starfive.git

netfilter: nf_nat_snmp_basic: replace ctinfo with dir.

The snmp_translate() receives ctinfo data to get dir value only.
because of caller already has dir value, we just replace ctinfo with dir.
