Subject: [NET]: Fix breakage, use ip_hdr() for DF check in ip_forward
Date: Sun, 25 Mar 2007 15:37:31 +0200	[thread overview]
Message-ID: <20070325133731.GH521@postel.suug.ch> (raw)
In-Reply-To: <11746948061847-git-send-email-jheffner@psc.edu>

The patch [NET] Move DF check to ip_forward broke net-2.6.22 as
skb->nh has been renamed to skb->network_header. Use ip_hdr().
