Pull networking updates from David Miller:
"Another merge window, another set of networking changes. I've heard
rumblings that the lightweight tunnels infrastructure has been voted
networking change of the year. But what do I know?

1) Add conntrack support to openvswitch, from Joe Stringer.

2) Initial support for VRF (Virtual Routing and Forwarding), which
allows the segmentation of routing paths without using multiple
devices. There are some semantic kinks to work out still, but
this is a reasonably strong foundation. From David Ahern.

3) Remove spinlock fro act_bpf fast path, from Alexei Starovoitov.

4) Ignore route nexthops with a link down state in ipv6, just like
ipv4. From Andy Gospodarek.

5) Remove spinlock from fast path of act_gact and act_mirred, from
Eric Dumazet.

6) Document the DSA layer, from Florian Fainelli.

7) Add netconsole support to bcmgenet, systemport, and DSA. Also
from Florian Fainelli.

8) Add Mellanox Switch Driver and core infrastructure, from Jiri
Pirko.

9) Add support for "light weight tunnels", which allow for
encapsulation and decapsulation without bearing the overhead of a
full blown netdevice. From Thomas Graf, Jiri Benc, and a cast of
others.

10) Add Identifier Locator Addressing support for ipv6, from Tom
Herbert.

11) Support fragmented SKBs in iwlwifi, from Johannes Berg.

12) Allow perf PMUs to be accessed from eBPF programs, from Kaixu Xia.

13) Add BQL support to 3c59x driver, from Loganaden Velvindron.

14) Stop using a zero TX queue length to mean that a device shouldn't
have a qdisc attached, use an explicit flag instead. From Phil
Sutter.

15) Use generic geneve netdevice infrastructure in openvswitch, from
Pravin B Shelar.

16) Add infrastructure to avoid re-forwarding a packet in software
that was already forwarded by a hardware switch. From Scott
Feldman.

17) Allow AF_PACKET fanout function to be implemented in a bpf
program, from Willem de Bruijn"

Merge branch 'lwtunnel'

Thomas Graf says:

====================
Lightweight & flow based encapsulation

This series combines the work previously posted by Roopa, Robert and
myself. It's according to what we discussed at NFWS. The motivation
of this series is to:

* Consolidate code between OVS and the rest of the kernel and get
rid of OVS vports and instead represent them as pure net_devices.
* Introduce a lightweight tunneling mechanism which enables flow
based encapsulation to improve scalability on both RX and TX.
* Do the above in an encapsulation unspecific way so that the
encapsulation type is eventually abstracted away from the user.
* Use the same forwarding decision for both native forwarding and
encapsulation thus allowing to switch between native IPv6 and
UDP encapsulation based on endpoint without requiring additional
logic

The fundamental changes introduces in this series are:
* A new RTA_ENCAP Netlink attribute for routes carrying encapsulation
instructions. Depending on the specified type, the instructions
apply to UDP encapsulations, MPLS and possible other in the future.
* Depending on the encapsulation type, the output function of the
dst is directly overwritten or the dst merely attaches metadata and
relies on a subsequent net_device to apply it to the packet. The
latter is typically used if an inner and outer IP header exist which
require two subsequent routing lookups to be performed.
* A new metadata_dst structure which can be attached to skbs to
carry metadata in between subsystems. This new metadata transport
is used to provide a single interface for VXLAN, routing and OVS
to communicate through metadata.

The OVS interfaces remain as-is but will transparently create a real
VXLAN net_device in the background. iproute2 is extended with a new
use cases:

VXLAN:
ip route add 40.1.1.1/32 encap vxlan id 10 dst 50.1.1.2 dev vxlan0

MPLS:
ip route add 10.1.1.0/30 encap mpls 200 via inet 10.1.1.1 dev swp1

Performance implications:
The additional memory allocation in the receive path should have
performance implications although it is not observable in standard
throughput tests if GRO is properly done. The correct net_device
model outweights the additional cost of the allocation. Furthermore,
this implication can be relaxed by reintroducing a direct unqueued
path from a software device to a consumer like bridge or OVS if
needed.

Merge branch 'basic-mpls-support'

Eric W. Biederman says:

====================
Basic MPLS support take 2

On top of my two pending neighbour table prep patches here is the mpls
support refactored to use them, and edited to not drop routes when
an interface goes down. Additionally the addition of RTA_LLGATEWAY
has been replaced with the addtion of RTA_VIA. RTA_VIA being an
attribute that includes the address family as well as the address
of the next hop.

MPLS is at it's heart simple and I have endeavoured to maintain that
simplicity in my implemenation.

This is an implementation of a RFC3032 forwarding engine, and basic MPLS
egress logic. Which should make linux sufficient to be a mpls
forwarding node or to be a LSA (Label Switched Router) as it says in all
of the MPLS documents. The ingress support will follow but it deserves
it's own discussion so I am pushing it separately.

mpls: Basic routing support

This change adds a new Kconfig option MPLS_ROUTING.

The core of this change is the code to look at an mpls packet received
from another machine. Look that packet up in a routing table and
forward the packet on.

Support of MPLS over ATM is not considered or attempted here. This
implemntation follows RFC3032 and implements the MPLS shim header that
can pass over essentially any network.

What RFC3021 refers to as the as the Incoming Label Map (ILM) I call
net->mpls.platform_label[]. What RFC3031 refers to as the Next Label
Hop Forwarding Entry (NHLFE) I call mpls_route. Though calling it the
label fordwarding information base (lfib) might also be valid.

Further the implemntation forwards packets as described in RFC3032.
There is no need and given the original motivation for MPLS a strong
discincentive to have a flexible label forwarding path. In essence
the logic is the topmost label is read, looked up, removed, and
replaced by 0 or more new lables and the sent out the specified
interface to it's next hop.

Quite a few optional features are not implemented here. Among them
are generation of ICMP errors when the TTL is exceeded or the packet
is larger than the next hop MTU (those conditions are detected and the
packets are dropped instead of generating an icmp error). The traffic
class field is always set to 0. The implementation focuses on IP over
MPLS and does not handle egress of other kinds of protocols.

Instead of implementing coordination with the neighbour table and
sorting out how to input next hops in a different address family (for
which there is value). I was lazy and implemented a next hop mac
address instead. The code is simpler and there are flavor of MPLS
such as MPLS-TP where neither an IPv4 nor an IPv6 next hop is
appropriate so a next hop by mac address would need to be implemented
at some point.

Two new definitions AF_MPLS and PF_MPLS are exposed to userspace.

Decoding the mpls header must be done by first byeswapping a 32bit bit
endian word into the local cpu endian and then bit shifting to extract
the pieces. There is no C bit-field that can represent a wire format
mpls header on a little endian machine as the low bits of the 20bit
label wind up in the wrong half of third byte. Therefore internally
everything is deal with in cpu native byte order except when writing
to and reading from a packet.

For management simplicity if a label is configured to forward out
an interface that is down the packet is dropped early. Similarly
if an network interface is removed rt_dev is updated to NULL
(so no reference is preserved) and any packets for that label
are dropped. Keeping the label entries in the kernel allows
the kernel label table to function as the definitive source
of which labels are allocated and which are not.
