From dedb67c4b4e5fa2e6e149a2ce93e7848aaa9d762 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Tue, 28 Mar 2017 22:27:32 +0530 Subject: netfilter: Add nfnl_msg_type() helper function Add and use nfnl_msg_type() function to replace opencoded nfnetlink message type. I suggested this change, Arushi Singhal made an initial patch to address this but was missing several spots.
