Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next

Steffen Klassert says: ==================== One patch to rename a newly introduced struct. The rest is the rework of the IPsec virtual tunnel interface for ipv6 to support inter address family tunneling and namespace crossing. 1) Rename the newly introduced struct xfrm_filter to avoid a conflict with iproute2. From Nicolas Dichtel. 2) Introduce xfrm_input_afinfo to access the address family dependent tunnel callback functions properly. 3) Add and use a IPsec protocol multiplexer for ipv6. 4) Remove dst_entry caching. vti can lookup multiple different dst entries, dependent of the configured xfrm states. Therefore it does not make to cache a dst_entry. 5) Remove caching of flow informations. vti6 does not use the the tunnel endpoint addresses to do route and xfrm lookups. 6) Update the vti6 to use its own receive hook. 7) Remove the now unused xfrm_tunnel_notifier. This was used from vti and is replaced by the IPsec protocol multiplexer hooks. 8) Support inter address family tunneling for vti6. 9) Check if the tunnel endpoints of the xfrm state and the vti interface are matching and return an error otherwise. 10) Enable namespace crossing for vti devices. ====================
