3.16.7-ckt18 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Borkmann <daniel@iogearbox.net>
commit e41b0bedba0293b9e1e8d1e8ed553104b9693656 upstream.
We previously register IPPROTO_ROUTING offload under inet6_add_offload(), but in error path, we try to unregister it with inet_del_offload(). This doesn't seem correct, it should actually be inet6_del_offload(), also ipv6_exthdrs_offload_exit() from that commit seems rather incorrect (it also uses rthdr_offload twice), but it got removed entirely later on.
