Subject: pull request (net): ipsec 2016-03-10

1) Add pmtu handling to vti, we need it do report
   pmtu informations for local generated packets.

2) The flowcache can hit an OOM condition if too
   many entries are in the gc_list. Fix this by
   counting the entries in the gc_list and refuse
   new allocations if the value is too high.

3) The inner headers are invalid after a xfrm transformation,
   so reset the skb encapsulation field ensure nobody tries
   access the inner headers. Otherwise tunnel divices stacked
   on top of xfrm may build the outer headers based on wrong
   informations.

4) Fix recource leeks for vti4/vti6 introduced with the
   pmtu handling.

Please pull or let me know if there are problems.

Thanks!
