The recent changes in ifupdown where all calls to 'ip link set' and
'ip addr set' are swapped give some problems with v4tunnels.
For plain ipv4 and ipv6 interfaces it works correct, other methods
not tried. The patch below change the behaviour back for v4tunnels
only.

Without the patch the following errors are shown:
RTNETLINK answers: Network is down
RTNETLINK answers: No route to host
and the tunnel is not fully brought up

With this patch all works as expected.
