Subject: [PATCH 4/5] ipv6: Add IPv6 multicast address flag defines
Date: Wed, 16 Feb 2011 00:19:20 +0100 [thread overview]
Message-ID: <1297811961-19249-5-git-send-email-linus.luessing@web.de> (raw)
In-Reply-To: <1297811961-19249-1-git-send-email-linus.luessing@web.de>
This commit adds the missing IPv6 multicast address flag defines to
complement the already existing multicast address scope defines and to
be able to check these flags nicely in the future.
Signed-off-by: Linus Lüssing <linus.luessing@web.de>
