Subject: [PATCH 05/12] netfilter: {ipt,ebt}_ULOG: rise warning on deprecation
Date: Wed,  5 Jun 2013 22:40:26 +0200	[thread overview]
Message-ID: <1370464832-4216-6-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1370464832-4216-1-git-send-email-pablo@netfilter.org>

This target has been superseded by NFLOG. Spot a warning
so we prepare removal in a couple of years.
