Jingoo Han 79ac7c9411 net: hippi: remove unnecessary pci_set_drvdata()
The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

Yann Droneaud d73aa2867f net: handle error more gracefully in socketpair()
This patch makes socketpair() use error paths which do not
rely on heavy-weight call to sys_close(): it's better to try
to push the file descriptor to userspace before installing
the socket file to the file descriptor, so that errors are
catched earlier and being easier to handle.

Using sys_close() seems to be the exception, while writing the
file descriptor before installing it look like it's more or less
the norm: eg. except for code used in init/, error handling
involve fput() and put_unused_fd(), but not sys_close().

This make socketpair() usage of sys_close() quite unusual.
So it deserves to be replaced by the common pattern relying on
fput() and put_unused_fd() just like, for example, the one used
in pipe(2) or recvmsg(2).

Three distinct error paths are still needed since calling
fput() on file structure returned by sock_alloc_file() will
implicitly call sock_release() on the associated socket
structure.

====================
Intel Wired LAN Driver Updates

This series contains updates to i40e, igb, ixgbe and ixgbevf.

Shannon provides a couple of i40e patches, first restricts the ethtool
diag test messages by using netif_info() macro to when the hardware
bit is enabled in the message level netdev message mask.  Second
provides a fix for when there is an out-of-range descriptor request.

Kamil provides a fix for i40e by updating the loopback enum types and
add information about the current loopback mode to data returned from
get_link_info().

Jesse provides a fix for i40e define name that was being mis-used.
I40E_ITR_NONE was being used as an ITRN register index by accident
because it was easily associated with the i40e Rx ITR and friends
defines, when it should be associated with the DYN_CTL register sets.

Jacob provides an update for ixgbevf Kconfig description since the VF
driver supports more than just the 82599 device.

Don and Alex provide a cleanup patch for ixgbe to make it where head,
tail, next to clean and next to use are all reset in a single function
for both Tx and Rx path.  Before, the code for this was spread out over
several areas which made it difficult to track what the values were for
each of the values.

Carolyn provides two igb patches to add a media switching feature for
i354 PHY's and new Media Auto Sense for 82580 devices only.

Aaron Sierra provides a fix for igb to resolve an issue with the 64-bit
PCI addresses being truncated because the return values of
pci_resource_start() and pci_resouce_end() were being cast to unsigned
long.

Guenter Roeck provides two igb patches, first simplifies the code by
attaching the hwmon sysfs attributes to hwmon device instead of the
PCI device.  Second fixes the temperature sensor attribute index by
setting it to 1 instead of 0 (per hwmon ABI).

Jack Morgenstein 7c6d74d23a mlx4_core: Roll back round robin bitmap allocation commit for CQs, SRQs, and MPTs
Commit f4ec9e9 "mlx4_core: Change bitmap allocator to work in round-robin fashion"
introduced round-robin allocation (via bitmap) for all resources which allocate
via a bitmap.

Round robin allocation is desirable for mcgs, counters, pd's, UARs, and xrcds.
These are simply numbers, with no involvement of ICM memory mapping.

Round robin is required for QPs, since we had a problem with immediate
reuse of a 24-bit QP number (commit f4ec9e9).

However, for other resources which use the bitmap allocator and involve
mapping ICM memory -- MPTs, CQs, SRQs -- round-robin is not desirable.

What happens in these cases is the following:

ICM memory is allocated and mapped in chunks of 256K.

Since the resource allocation index goes up monotonically, the allocator
will eventually require mapping a new chunk. Now, chunks are also unmapped
when their reference count goes back to zero.  Thus, if a single app is
running and starts/exits frequently we will have the following situation:

When the app starts, a new chunk must be allocated and mapped.

When the app exits, the chunk reference count goes back to zero, and the
chunk is unmapped and freed. Therefore, the app must pay the cost of allocation
and mapping of ICM memory each time it runs (although the price is paid only when
allocating the initial entry in the new chunk).

For apps which allocate MPTs/SRQs/CQs and which operate as described above,
this presented a performance problem.

We therefore roll back the round-robin allocator modification for MPTs, CQs, SRQs.

We were already registering MDIO bus, but we were not connecting bgmac

At the same time it's possible to drop our internal PHY management.
This is a "standard" PHY, so the "Generic PHY" driver works perfectly
fine with this. Don't duplicate the code.
Finally make use of phy_ethtool_[gs]set functions instead implementing
them from scratch.

This change was successfully tested on BCM5357. I was able to

David S. Miller 4e58879346 Merge branch 'neigh'
Jiri Pirko says:

====================
neigh: respect default parms values

This is a long standing regression. But since the patchset is bigger and
the regression happened in 2007, I'm proposing this to net-next instead.

Basically the problem is that if user wants to use /etc/sysctl.conf to specify
default values of neigh related params, he is not able to do that.

The reason is that the default values are copied to dev instance right after
netdev is registered. And that is way to early. The original behaviour
for ipv4 was that this happened after first address was assigned to device.
For ipv6 this was apparently from the very beginning.

So this patchset basically reverts the behaviour back to what it was in 2007 for
ipv4 and changes the behaviour for ipv6 so they are both the same.

Now that we're creating inet devices earlier, this changes the behaviour
of default neigh parms values in an incompatible way (see bug #8519).

This patch creates a compromise by setting the default values at the
same point as before but only for those that have not been explicitly
set by the user since the inet device's creation.

This patch converts the neigh param members to an array. This allows easier
manipulation which will be needed later on to provide better management of
default values.

Florian Fainelli says:

====================
net: phy: consolidate PHY reset

This patchset consolidates the PHY reset through the MII BMCR
register by using a central place were this is done.

This patchset resumes the work Kyle Moffett started here:
https://lkml.org/lkml/2011/10/20/301

Note that at this point, drivers doing funky things after issuing
a PHY reset using phy_init_hw() will still suffer from PHY state
machine problems, this will be taken care of later on.

Florian Fainelli 0c9eb5b931 net: sh_eth: do not issue a wild PHY reset through BMCR
The sh_eth driver issues an uncontrolled PHY reset through the MII
register BMCR but fails to wait for the reset to complete, and will also
implicitely wipe out all possible PHY fixups applied. Use phy_init_hw()
which remedies both problems.

Florian Fainelli 01b0114e06 net: tc35815: use phy_init_hw for PHY reset
Instead of open-coding the PHY reset through MII BMCR, use phy_init_hw()
which does that for us and also makes sure that any PHY specific fixups
are applied.

Florian Fainelli 78de53f05c net: pxa168_eth: use phy_init_hw for PHY reset
Instead of open-coding a PHY reset through the MII BMCR register, use
phy_init_hw() which does this for us and ensures that PHY device fixups
are also applied. We also remove a call to ethernet_phy_reset() which is
now unncessary since phy_attach() calls phy_attach_direct() which in
turns calls phy_init_hw().

Florian Fainelli 7cd1463664 net: mv643xx_eth: use phy_init_hw to reset PHY
Instead of open-coding a PHY reset through the MII BMCR register, use
phy_init_hw() which does that for us and will also make sure that PHY
fixups are applied if required. We also remove a call to phy_reset()
due to the following sequence of calls in the driver:

phy_scan()
	-> phy_connect()
		-> phy_connect_direct()
			-> phy_attach_direct()
				-> phy_init_hw()

and we only have a call to phy_init() after phy_scan().

Florian Fainelli 87aa9f9c61 net: phy: consolidate PHY reset in phy_init_hw()
There are quite a lot of drivers touching a PHY device MII_BMCR
register to reset the PHY without taking care of:

1) ensuring that BMCR_RESET is cleared after a given timeout
2) the PHY state machine resuming to the proper state and re-applying
potentially changed settings such as auto-negotiation

Introduce phy_poll_reset() which will take care of polling the MII_BMCR
for the BMCR_RESET bit to be cleared after a given timeout or return a
timeout error code.

In order to make sure the PHY is in a correct state, phy_init_hw() first
issues a software reset through MII_BMCR and then applies any fixups.
