Subject: [PATCH 3/5] bridge: Add missing ntohs()s for MLDv2 report parsing
Date: Wed, 16 Feb 2011 00:19:19 +0100	[thread overview]
Message-ID: <1297811961-19249-4-git-send-email-linus.luessing@web.de> (raw)
In-Reply-To: <1297811961-19249-1-git-send-email-linus.luessing@web.de>

The nsrcs number is 2 Byte wide, therefore we need to call ntohs()
before using it.
