From fc423ae81487e906141f700c7b3515328ff62b7c Mon Sep 17 00:00:00 2001 From: Arturo Borrero Date: Thu, 9 Jan 2014 12:19:06 +0100 Subject: src: rework and generalize the build/parse system The intention behind this patch is to prepare the introduction of the new API that will allow us to parse files that contain the rule-sets expressed in XML/JSON format. This adds the NFT_PARSE_BUFFER that indicates that the input is provided in a buffer, which is what we currently support.
