Subject: [PATCH 2/7] netfilter: Add MODULE_DESCRIPTION entries to kernel modules

From: Rob Gill <rrobgill@...tonmail.com>

The user tool modinfo is used to get information on kernel modules, including a
description where it is available.

This patch adds a brief MODULE_DESCRIPTION to netfilter kernel modules
(descriptions taken from Kconfig file or code comments)
