436c2a5036 asix: Do full reset during ax88772_bind
commit 3cc81d85ee ("asix: Don't reset PHY on if_up for ASIX 88772")
causes the ethernet on Arndale to no longer function. This appears to
be because the Arndale ethernet requires a full reset before it will
function correctly, however simply reverting the above patch causes
problems with ethtool settings getting reset.

It seems the problem is that the ethernet is not properly reset during
bind, and indeed the code in ax88772_bind that resets the device is a
very small subset of the actual ax88772_reset function. This patch uses
ax88772_reset in place of the existing reset code in ax88772_bind which
removes some code duplication and fixes the ethernet on Arndale.

It is still possible that the original patch causes some issues with
suspend and resume but that seems like a separate issue and I haven't
had a chance to test that yet.

d59c876dd6 r8152: stop submitting intr for -EPROTO
For Renesas USB 3.0 host controller, when unplugging the usb hub which
has the RTL8153 plugged, the driver would get -EPROTO for interrupt
transfer. There is high probability to get the information of "HC died;
cleaning up", if the driver continues to submit the interrupt transfer
before the disconnect() is called.

95ff886887 ax88179_178a: fix bonding failure
The following patch fixes a bug which causes the ax88179_178a driver to be
incapable of being added to a bond.

When I brought up the issue with the bonding maintainers, they indicated
that the real problem was with the NIC driver which must return zero for
success (of setting the MAC address). I see that several other NIC drivers
follow that pattern by either simply always returing zero, or by passing
through a negative (error) result while rewriting any positive return code
to zero. With that same philisophy applied to the ax88179_178a driver, it
allows it to work correctly with the bonding driver.

I believe this is suitable for queuing in -stable, as it's a small, simple,
and obvious fix that corrects a defect with no other known workaround.

This patch is against vanilla 3.17(.0).

Remove calling cancel_delayed_work_sync() for runtime suspend,
because it would cause dead lock. Instead, return -EBUSY to
avoid the device enters suspending if the net is running and
the delayed work is pending or running. The delayed work would
try to wake up the device later, so the suspending is not
necessary.

Pull networking updates from David Miller:
 "Most notable changes in here:

   1) By far the biggest accomplishment, thanks to a large range of
      contributors, is the addition of multi-send for transmit.  This is
      the result of discussions back in Chicago, and the hard work of
      several individuals.

      Now, when the ->ndo_start_xmit() method of a driver sees
      skb->xmit_more as true, it can choose to defer the doorbell
      telling the driver to start processing the new TX queue entires.

      skb->xmit_more means that the generic networking is guaranteed to
      call the driver immediately with another SKB to send.

      There is logic added to the qdisc layer to dequeue multiple
      packets at a time, and the handling mis-predicted offloads in
      software is now done with no locks held.

      Finally, pktgen is extended to have a "burst" parameter that can
      be used to test a multi-send implementation.

      Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
      virtio_net

      Adding support is almost trivial, so export more drivers to
      support this optimization soon.

      I want to thank, in no particular or implied order, Jesper
      Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
      Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
      David Tat, Hannes Frederic Sowa, and Rusty Russell.

   2) PTP and timestamping support in bnx2x, from Michal Kalderon.

   3) Allow adjusting the rx_copybreak threshold for a driver via
      ethtool, and add rx_copybreak support to enic driver.  From
      Govindarajulu Varadarajan.

   4) Significant enhancements to the generic PHY layer and the bcm7xxx
      driver in particular (EEE support, auto power down, etc.) from
      Florian Fainelli.

   5) Allow raw buffers to be used for flow dissection, allowing drivers
      to determine the optimal "linear pull" size for devices that DMA
      into pools of pages.  The objective is to get exactly the
      necessary amount of headers into the linear SKB area pre-pulled,
      but no more.  The new interface drivers use is eth_get_headlen().
      From WANG Cong, with driver conversions (several had their own
      by-hand duplicated implementations) by Alexander Duyck and Eric
      Dumazet.

   6) Support checksumming more smoothly and efficiently for
      encapsulations, and add "foo over UDP" facility.  From Tom
      Herbert.

   7) Add Broadcom SF2 switch driver to DSA layer, from Florian
      Fainelli.

   8) eBPF now can load programs via a system call and has an extensive
      testsuite.  Alexei Starovoitov and Daniel Borkmann.

   9) Major overhaul of the packet scheduler to use RCU in several major
      areas such as the classifiers and rate estimators.  From John
      Fastabend.

  10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
      Duyck.

  11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
      Dumazet.

  12) Add Datacenter TCP congestion control algorithm support, From
      Florian Westphal.

  13) Reorganize sk_buff so that __copy_skb_header() is significantly
      faster.  From Eric Dumazet"

when ethtool is used to set autonegotiation to 'off', half

It can be tested by:
 ifconfig eth0 down
 ethtool -s eth0 autoneg off speed 10 duplex half
 ifconfig eth0 up

Then checking 'dmesg' for the link speed.

d70b113723 r8152: disable ALDPS
If the hw is in ALDPS mode, the hw may have no response for accessing
the most registers. Therefore, the ALDPS should be disabled before
accessing the hw in rtl_ops.init(), rtl_ops.disable(), rtl_ops.up(),
and rtl_ops.down(). Regardless of rtl_ops.enable(), because the hw
wouldn't enter ALDPS mode when linking on. The hw would enter the
ALDPS mode after several seconds when link down occurs and the ALDPS
is enabled.

Exchange the location of rtl8152_set_mac_address() and
set_ethernet_addr(). Then, the set_ethernet_addr() could
set the MAC address by calling rtl8152_set_mac_address()
later.

1764bcd9fe r8152: reduce the number of Tx
Because the Tx has the features of stopping queue and aggregation,
We don't need many tx buffers. Change the tx number from 10 to 4
to reduce the usage of the memory. This could save 16K * 6 bytes
memory.

269f8cb260 net: fix USB network driver config option.
It must be tristate to avoid broken dependencies with kernel built-in
usb network drivers when usb support is module only.

When net config option is set, least surprize default should match usb.

Wireless RNDIS USB driver used to select USB_USBNET. USB_USBNET now
depends on USB_NET_DRIVERS so the latter should be selected as well.

Conflicts:
	drivers/net/Makefile
	net/ipv6/sysctl_net_ipv6.c

Two ipv6_table_template[] additions overlap, so the index
of the ipv6_table[x] assignments needed to be adjusted.

In the drivers/net/Makefile case, we've gotten rid of the
garbage whereby we had to list every single USB networking
driver in the top-level Makefile, there is just one
"USB_NETWORKING" that guards everything.

1bb5a356c3 net: reduce USB network driver config options.
USB network drivers are already handled in drivers/net/usb/Kconfig.
Let's save the maintenance burden of dependencies in drivers/net/Makefile.

The newly introduced USB_NET_DRIVERS umbrella config option defaults
to 'y' so as to minimize the changes of behavior.

dbcdd4d58c cdc_subset: deal with a device that needs reset for timeout
This device needs to be reset to recover from a timeout.
Unfortunately this can be handled only at the level of
the subdrivers.

This reverts commit 20fbe3ae99.

As reported by Stephen Rothwell, it causes compile failures in certain
configurations:

  drivers/net/usb/cdc_subset.c:360:15: error: 'dummy_prereset' undeclared here (not in a function)
    .pre_reset = dummy_prereset,
                 ^
  drivers/net/usb/cdc_subset.c:361:16: error: 'dummy_postreset' undeclared here (not in a function)
    .post_reset = dummy_postreset,
                  ^

c472ab68ad cdc-ether: clean packet filter upon probe
There are devices that don't do reset all the way. So the packet filter should
be set to a sane initial value. Failure to do so leads to intermittent failures
of DHCP on some systems under some conditions.
