Subject: [PATCH] ip6_tunnel dont update the mtu on the route.
Date: Tue, 19 Oct 2010 15:50:47 +0200	[thread overview]
Message-ID: <1287496247-24127-1-git-send-email-Anders.Franzen@ericsson.com> (raw)

From: Anders Franzen <anders.franzen@ericsson.com>

The ip6_tunnel device did not unset the flag,
IFF_XMIT_DST_RELEASE. This will make the dev layer
to release the dst before calling the tunnel.
The tunnel will not update any mtu/pmtu info, since
it does not have a dst on the skb.
