Pull networking updates from David Miller:
 "Highlights:

   1) Steady transitioning of the BPF instructure to a generic spot so
      all kernel subsystems can make use of it, from Alexei Starovoitov.

   2) SFC driver supports busy polling, from Alexandre Rames.

   3) Take advantage of hash table in UDP multicast delivery, from David
      Held.

   4) Lighten locking, in particular by getting rid of the LRU lists, in
      inet frag handling.  From Florian Westphal.

   5) Add support for various RFC6458 control messages in SCTP, from
      Geir Ola Vaagland.

   6) Allow to filter bridge forwarding database dumps by device, from
      Jamal Hadi Salim.

   7) virtio-net also now supports busy polling, from Jason Wang.

   8) Some low level optimization tweaks in pktgen from Jesper Dangaard
      Brouer.

   9) Add support for ipv6 address generation modes, so that userland
      can have some input into the process.  From Jiri Pirko.

  10) Consolidate common TCP connection request code in ipv4 and ipv6,
      from Octavian Purdila.

  11) New ARP packet logger in netfilter, from Pablo Neira Ayuso.

  12) Generic resizable RCU hash table, with intial users in netlink and
      nftables.  From Thomas Graf.

  13) Maintain a name assignment type so that userspace can see where a
      network device name came from (enumerated by kernel, assigned
      explicitly by userspace, etc.) From Tom Gundersen.

  14) Automatic flow label generation on transmit in ipv6, from Tom
      Herbert.

  15) New packet timestamping facilities from Willem de Bruijn, meant to
      assist in measuring latencies going into/out-of the packet
      scheduler, latency from TCP data transmission to ACK, etc"

The PHY's MMD register accesses are handled by the PAL framework
by default, but can be overridden by a specific PHY driver if
required. This could be the case if a PHY was released for
manufacturing before the MMD PHY register definitions were
standardized by the IEEE. Most modern PHYs will be able to use
the generic PAL framework for accessing the PHY's MMD registers.
An example of such usage is for Energy Efficient Ethernet support,
implemented in the PAL. This support uses the PAL to access MMD
registers for EEE query and configuration if the PHY supports
the IEEE standard access mechanisms, or can use the PHY's specific
access interfaces if overridden by the specific PHY driver. See
the Micrel driver in drivers/net/phy/ for an example of how this
can be implemented.

Tuning NIC for max performance
==============================
The default NIC setting are (likely) not tuned for pktgen's artificial
overload type of benchmarking, as this could hurt the normal use-case.
Specifically increasing the TX ring buffer in the NIC:
# ethtool -G ethX tx 1024
A larger TX ring can improve pktgen's performance, while it can hurt
in the general case, 1) because the TX ring buffer might get larger
than the CPUs L1/L2 cache, 2) because it allow more queueing in the
NIC HW layer (which is bad for bufferbloat).
One should be careful to conclude, that packets/descriptors in the HW
TX ring cause delay. Drivers usually delay cleaning up the
ring-buffers (for various performance reasons), thus packets stalling
the TX ring, might just be waiting for cleanup.
This cleanup issues is specifically the case, for the driver ixgbe
(Intel 82599 chip). This driver (ixgbe) combine TX+RX ring cleanups,
and the cleanup interval is affected by the ethtool --coalesce setting
of parameter "rx-usecs".
For ixgbe use e.g "30" resulting in approx 33K interrupts/sec (1/30*10^6):
# ethtool -C ethX rx-usecs 30

SOF_TIMESTAMPING_RAW_HARDWARE is set. No assumptions about its
relation to system time should be made.
hwtimetrans is the hardware time stamp transformed so that it
corresponds as good as possible to system time. This correlation is
not perfect; as a consequence, sorting packets received via different
NICs by their hwtimetrans may differ from the order in which they were
received. hwtimetrans may be non-monotonic even for the same NIC.
Filled in if SOF_TIMESTAMPING_SYS_HARDWARE is set. Requires support
by the network device and will be empty without that support.
hwtimetrans is always zero. This field is deprecated. It used to hold
hw timestamps converted to system time. Instead, expose the hardware
clock device on the NIC directly as a HW PTP clock source, to allow
time conversion in userspace and optionally synchronize system time
with a userspace PTP stack such as linuxptp. For the PTP clock API,
see Documentation/ptp/ptp.txt.
