Pull networking updates from David Miller:

 1) Add VF IPSEC offload support in ixgbe, from Shannon Nelson.

 2) Add zero-copy AF_XDP support to i40e, from Björn Töpel.

 3) All in-tree drivers are converted to {g,s}et_link_ksettings() so we
    can get rid of the {g,s}et_settings ethtool callbacks, from Michal
    Kubecek.

 4) Add software timestamping to veth driver, from Michael Walle.

 5) More work to make packet classifiers and actions lockless, from Vlad
    Buslov.

 6) Support sticky FDB entries in bridge, from Nikolay Aleksandrov.

 7) Add ipv6 version of IP_MULTICAST_ALL sockopt, from Andre Naujoks.

 8) Support batching of XDP buffers in vhost_net, from Jason Wang.

 9) Add flow dissector BPF hook, from Petar Penkov.

10) i40e vf --> generic iavf conversion, from Jesse Brandeburg.

11) Add NLA_REJECT netlink attribute policy type, to signal when users
    provide attributes in situations which don't make sense. From
    Johannes Berg.

12) Switch TCP and fair-queue scheduler over to earliest departure time
    model. From Eric Dumazet.

13) Improve guest receive performance by doing rx busy polling in tx
    path of vhost networking driver, from Tonghao Zhang.

14) Add per-cgroup local storage to bpf

15) Add reference tracking to BPF, from Joe Stringer. The verifier can
    now make sure that references taken to objects are properly released
    by the program.

16) Support in-place encryption in TLS, from Vakul Garg.

17) Add new taprio packet scheduler, from Vinicius Costa Gomes.

18) Lots of selftests additions, too numerous to mention one by one here
    but all of which are very much appreciated.

19) Support offloading of eBPF programs containing BPF to BPF calls in
    nfp driver, frm Quentin Monnet.

20) Move dpaa2_ptp driver out of staging, from Yangbo Lu.

21) Lots of u32 classifier cleanups and simplifications, from Al Viro.

22) Add new strict versions of netlink message parsers, and enable them
    for some situations. From David Ahern.

23) Evict neighbour entries on carrier down, also from David Ahern.

24) Support BPF sk_msg verdict programs with kTLS, from Daniel Borkmann
    and John Fastabend.

25) Add support for filtering route dumps, from David Ahern.

26) New igc Intel driver for 2.5G parts, from Sasha Neftin et al.

27) Allow vxlan enslavement to bridges in mlxsw driver, from Ido
    Schimmel.

28) Add queue and stack map types to eBPF, from Mauricio Vasquez B.

29) Add back byte-queue-limit support to r8169, with all the bug fixes
    in other areas of the driver it works now! From Florian Westphal and
    Heiner Kallweit.

-* Add a DPAA2 MAC kernel driver in order to allow PHY management; currently
-  the DPMAC objects and their link to DPNIs are handled by MC internally
-  and all PHYs are seen as fixed-link
-* add more debug support: decide how to expose detailed debug statistics,
-  add ingress error queue support
-* MC firmware uprev; the DPAA2 objects used by the Ethernet driver need to
-  be kept in sync with binary interface changes in MC
-* refine README file
-* cleanup
-
-NOTE: None of the above is must-have before getting the DPAA2 Ethernet driver
-out of staging. The main requirement for that is to have the drivers it
-depends on, fsl-mc bus and DPIO driver, moved to drivers/bus and drivers/soc
-respectively.

-DPAA2 Ethernet driver
-===============================
-
-:Copyright: |copy| 2017-2018 NXP
-
-This file provides documentation for the Freescale DPAA2 Ethernet driver.
-
-Supported Platforms
-===================
-This driver provides networking support for Freescale DPAA2 SoCs, e.g.
-LS2080A, LS2088A, LS1088A.
-
-
-Architecture Overview
-=====================
-Unlike regular NICs, in the DPAA2 architecture there is no single hardware block
-representing network interfaces; instead, several separate hardware resources
-concur to provide the networking functionality:
-
-- network interfaces
-- queues, channels
-- buffer pools
-- MAC/PHY
-
-All hardware resources are allocated and configured through the Management
-Complex (MC) portals. MC abstracts most of these resources as DPAA2 objects
-and exposes ABIs through which they can be configured and controlled. A few
-hardware resources, like queues, do not have a corresponding MC object and
-are treated as internal resources of other objects.
-
-For a more detailed description of the DPAA2 architecture and its object
-abstractions see *Documentation/networking/dpaa2/overview.rst*.
-
-Each Linux net device is built on top of a Datapath Network Interface (DPNI)
-object and uses Buffer Pools (DPBPs), I/O Portals (DPIOs) and Concentrators
-(DPCONs).
-

-
-Datapath I/O (DPIO) portals provide enqueue and dequeue services, data
-availability notifications and buffer pool management. DPIOs are shared between
-all DPAA2 objects (and implicitly all DPAA2 kernel drivers) that work with data
-frames, but must be affine to the CPUs for the purpose of traffic distribution.
-
-Frames are transmitted and received through hardware frame queues, which can be
-grouped in channels for the purpose of hardware scheduling. The Ethernet driver
-enqueues TX frames on egress queues and after transmission is complete a TX
-confirmation frame is sent back to the CPU.
-
-When frames are available on ingress queues, a data availability notification
-is sent to the CPU; notifications are raised per channel, so even if multiple
-queues in the same channel have available frames, only one notification is sent.
-After a channel fires a notification, is must be explicitly rearmed.
-
-Each network interface can have multiple Rx, Tx and confirmation queues affined
-to CPUs, and one channel (DPCON) for each CPU that services at least one queue.
-DPCONs are used to distribute ingress traffic to different CPUs via the cores'
-affine DPIOs.
-
-The role of hardware buffer pools is storage of ingress frame data. Each network
-interface has a privately owned buffer pool which it seeds with kernel allocated
-buffers.
-
-
-DPNIs are decoupled from PHYs; a DPNI can be connected to a PHY through a DPMAC
-object or to another DPNI through an internal link, but the connection is
-managed by MC and completely transparent to the Ethernet driver.

-
-Creating a Network Interface
-============================
-A net device is created for each DPNI object probed on the MC bus. Each DPNI has
-a number of properties which determine the network interface configuration
-options and associated hardware resources.
-
-DPNI objects (and the other DPAA2 objects needed for a network interface) can be
-added to a container on the MC bus in one of two ways: statically, through a
-Datapath Layout Binary file (DPL) that is parsed by MC at boot time; or created
-dynamically at runtime, via the DPAA2 objects APIs.
-
-
-Features & Offloads
-===================
-Hardware checksum offloading is supported for TCP and UDP over IPv4/6 frames.
-The checksum offloads can be independently configured on RX and TX through
-ethtool.
-
-Hardware offload of unicast and multicast MAC filtering is supported on the
-ingress path and permanently enabled.
-
-Scatter-gather frames are supported on both RX and TX paths. On TX, SG support
-is configurable via ethtool; on RX it is always enabled.
-
-The DPAA2 hardware can process jumbo Ethernet frames of up to 10K bytes.
-
-The Ethernet driver defines a static flow hashing scheme that distributes
-traffic based on a 5-tuple key: src IP, dst IP, IP proto, L4 src port,
-L4 dst port. No user configuration is supported for now.
-
-Hardware specific statistics for the network interface as well as some
-non-standard driver stats can be consulted through ethtool -S option.
