From b1c96ed37ceeef5573402d4af202897edaf1e4b8 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Sat, 11 Apr 2015 02:27:36 +0100 Subject: netfilter: nf_tables: add register parsing/dumping helpers Add helper functions to parse and dump register values in netlink attributes. These helpers will later be changed to take care of translation between the old 128 bit and the new 32 bit register numbers.
