Subject: ip6_tunnel dont update the mtu on the route.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7e223de84b73c621b90755dc4d8c8128e673b529;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ip6_tunnel dont update the mtu on the route.

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.
