Subject: [PATCH 7/8] netfilter: IPv6: fix DSCP mangle code
Date: Tue, 10 May 2011 12:05:58 +0200 [thread overview]
Message-ID: <1305021959-2980-8-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1305021959-2980-1-git-send-email-pablo@netfilter.org>
From: Fernando Luis Vazquez Cao <fernando@oss.ntt.co.jp>
The mask indicates the bits one wants to zero out, so it needs to be
inverted before applying to the original TOS field.
