Pull yet more networking updates from David Miller:

1) Various fixes to the new Redpine Signals wireless driver, from
Fariya Fatima.

2) L2TP PPP connect code takes PMTU from the wrong socket, fix from
Dmitry Petukhov.

3) UFO and TSO packets differ in whether they include the protocol
header in gso_size, account for that in skb_gso_transport_seglen().
From Florian Westphal.

4) If VLAN untagging fails, we double free the SKB in the bridging
output path. From Toshiaki Makita.

5) Several call sites of sk->sk_data_ready() were referencing an SKB
just added to the socket receive queue in order to calculate the
second argument via skb->len. This is dangerous because the moment
the skb is added to the receive queue it can be consumed in another
context and freed up.

It turns out also that none of the sk->sk_data_ready()
implementations even care about this second argument.

So just kill it off and thus fix all these use-after-free bugs as a
side effect.

6) Fix inverted test in tcp_v6_send_response(), from Lorenzo Colitti.

7) pktgen needs to do locking properly for LLTX devices, from Daniel
Borkmann.

8) xen-netfront driver initializes TX array entries in RX loop :-) From
Vincenzo Maffione.

9) After refactoring, some tunnel drivers allow a tunnel to be
configured on top itself. Fix from Nicolas Dichtel.
