dd19f83d6c rocker: hook ndo_neigh_destroy to cleanup neigh refs in driver
Rocker driver tracks arp_tbl neighs to resolve IPv4 route nexthops.  The
driver uses NETEVENT_NEIGH_UPDATE for neigh adds and updates, but there is
no event when the neigh is removed from the device (such as when the device
goes admin down).  This patches hooks ndo_neigh_destroy so the driver can
know when a neigh is removed from the device.  In response, the driver will
purge the neigh entry from its internal tbl.

I didn't find an in-tree users of ndo_neigh_destroy, so I'm not sure if
this ndo is vestigial or if there are out-of-tree users.  In any case, it
does what I need here.  An alternative design would be to generate
NETEVENT_NEIGH_UPDATE event when neigh is being destroyed, setting state to
NUD_NONE so driver knows neigh entry is dead.

6bc6d0a881 dsa: Support multiple MDIO busses
When using a cluster of switches, some topologies will have an MDIO
bus per switch, not one for the whole cluster. Allow this to be
represented in the device tree, by adding an optional mii-bus property
at the switch level. The old platform_device method of instantiation
supports this already, so only the device tree binding needs extending
with an additional optional phandle.

073e570d7c Input: alps - only Dell laptops have separate button bits for v2 dualpoint sticks
It turns out that only Dell laptops have the separate button bits for
v2 dualpoint sticks and that commit 92bac83dd7 ("Input: alps - non
interleaved V2 dualpoint has separate stick button bits") causes
regressions on Toshiba laptops.

This commit adds a check for Dell laptops to the code for handling these
extra button bits, fixing this regression.

This patch has been tested on a Dell Latitude D620 to make sure that it
does not reintroduce the original problem.

c934b36127 phy: ti-pipe3: i783 workaround for SATA lockup after dpll unlock/relock
SATA_PLL_SOFT_RESET bit of CTRL_CORE_SMA_SW_0 must be toggled
between a SATA DPLL unlock and re-lock to prevent SATA lockup.

Introduce a new DT parameter 'syscon-pllreset' to provide the syscon
regmap access to this register which sits in the control module.

If the register is not provided we fallback to the old behaviour
i.e. SATA DPLL refclk will not be disabled and we prevent SoC low
power states.

8013d1d7ea net/ipv6: add sysctl option accept_ra_min_hop_limit
Commit 6fd99094de ("ipv6: Don't reduce hop limit for an interface")
disabled accept hop limit from RA if it is smaller than the current hop
limit for security stuff. But this behavior kind of break the RFC definition.

RFC 4861, 6.3.4.  Processing Received Router Advertisements
   A Router Advertisement field (e.g., Cur Hop Limit, Reachable Time,
   and Retrans Timer) may contain a value denoting that it is
   unspecified.  In such cases, the parameter should be ignored and the
   host should continue using whatever value it is already using.

   If the received Cur Hop Limit value is non-zero, the host SHOULD set
   its CurHopLimit variable to the received value.

So add sysctl option accept_ra_min_hop_limit to let user choose the minimum
hop limit value they can accept from RA. And set default to 1 to meet RFC
standards.

71382bc043 net: netcp: Fixes efuse mac addr swap on k2e and k2l
On some of the K2E and K2L platforms, the two DWORDs in
efuse occupied by the pre-programmed mac address for
slave port 1 are swapped.  To workaround this issue,
this patch adds a new define NETCP_EFUSE_ADDR_SWAP (2)
which signifies the occurrence of such swapping so that
the driver can take proper action.  The flag can be
enabled in the corresponding netcp interface dts binding
as efuse-mac = <2>  under the corresponding netcp
interface node.

Pull SCSI target fixes from Nicholas Bellinger:
 "This series is larger than what I'd normally be conformable with
  sending for a -rc5 PULL request..

  However, the bulk of the series is localized to qla2xxx target
  specific fixes that address a number of real-world correctness issues,
  that have been outstanding on the list for ~6 weeks now.  They where
  submitted + verified + acked by the HW LLD vendor, contributed by a
  major production customer of the code, and are marked for v3.18.y
  stable code.

  That said, I don't see a good reason to wait another month to get
  these fixes into mainline.

  Beyond the qla2xx specific fixes, this series also includes:

   - bugfix for a long standing use-after-free in iscsi-target during
     TPG shutdown + demo-mode sessions.

   - bugfix for a >= v4.0 regression OOPs in iscsi-target during a
     iscsi_start_kthreads() failure.

   - bugfix for a >= v4.0 regression hang in iscsi-target for iser
     explicit session/connection logout.

   - bugfix for a iser-target bug where a early CMA REJECTED status
     during login triggers a NULL pointer dereference OOPs.

   - bugfixes for a handful of v4.2-rc1 specific regressions related to
     the larger set of recent backend configfs attribute changes.

  A big thanks to QLogic + Pure Storage for the qla2xxx target bugfixes"

4cba5c2103 of_mdio: add new DT property 'managed' to specify the PHY management type
Currently the PHY management type is selected by the MAC driver arbitrary.
The decision is based on the presence of the "fixed-link" node and on a
will of the driver's authors.
This caused a regression recently, when mvneta driver suddenly started
to use the in-band status for auto-negotiation on fixed links.
It appears the auto-negotiation may not work when expected by the MAC driver.
Sebastien Rannou explains:
<< Yes, I confirm that my HW does not generate an in-band status. AFAIK, it's
a PHY that aggregates 4xSGMIIs to 1xQSGMII ; the MAC side of the PHY (with
inband status) is connected to the switch through QSGMII, and in this context
we are on the media side of the PHY. >>
https://lkml.org/lkml/2015/7/10/206

This patch introduces the new string property 'managed' that allows
the user to set the management type explicitly.
The supported values are:
"auto" - default. Uses either MDIO or nothing, depending on the presence
of the fixed-link node
"in-band-status" - use in-band status

Intel Wired LAN Driver Updates 2015-07-17

This series contains updates to igb, ixgbe, ixgbevf, i40e, bnx2x,
freescale, siena and dp83640.

Jacob provides several patches to clarify the intended way to implement
both SIOCSHWTSTAMP and ethtool's get_ts_info().  It is okay to support
the specific filters in SIOCSHWTSTAMP by upscaling them to the generic
filters.

Alex Duyck provides a igb patch to pull the time stamp from the fragment
before it gets added to the skb, to avoid a possible issue in which the
fragment can possibly be less than IGB_RX_HDR_LEN due to the time stamp
being pulled after the copybreak check.  Also provides a ixgbevf patch to
fold the ixgbevf_pull_tail() call into ixgbevf_add_rx_frag(), which gives
the advantage that the fragment does not have to be modified after it is
added to the skb.

Fan provides patches for ixgbe/ixgbevf to set the receive hash type
based on receive descriptor RSS type.

Todd provides a fix for igb where on check for link on any media other
than copper was not being detected since it was looking on the incorrect
PHY page (due to the page being used gets switched before the function
to check link gets executed).

eff3cddc22 clarify implementation of ethtool's get_ts_info op
This patch adds some clarification about the intended way to implement
both SIOCSHWTSTAMP and ethtool's get_ts_info. The HWTSTAMP API has
several Rx filters which are very specific, as well as more general
filters. The specific filters really only exist to support some broken
hardware which can't fully implement the generic filters. This patch
adds clarification that it is okay to support the specific filters in
SIOCSHWTSTAMP by upscaling them to the generic filters. In addition,
update the header for ethtool_ts_info to specify that drivers ought to
only report the filters they support without upscaling in this manner.

e1e50e1e1e imx-drm: fixes for parallel-display, imx-tve, and ipu-common
These patches fix the parallel-display driver to use the standard OF
 graph bindings for connecting a drm_panel via device tree instead of
 an undocumented, driver specific device tree property, take care to
 disable all IPU interrupts before setting up the irq chip to fix a
 kexec lockup, and fix VGA output on i.MX53-QSB boards by correcting
 the media bus format set by the imx-tve driver.
