Hannes Frederic Sowa b6a7719aed ipv4: hash net ptr into fragmentation bucket selection
As namespaces are sometimes used with overlapping ip address ranges,
we should also use the namespace as input to the hash to select the ip
fragmentation counter bucket.

Power up the GPHY while we are bringing-up the network interface, and
conversely, upon bring down, power the GPHY down. In order to avoid

Marcelo Ricardo Leitner 24c0e6838c vxlan: simplify if clause in dev_close
Dan Carpenter's static checker warned that in vxlan_stop we are checking
if 'vs' can be NULL while later we simply derreference it.

As after commit 56ef9c909b ("vxlan: Move socket initialization to
within rtnl scope") 'vs' just cannot be NULL in vxlan_stop() anymore, as
the interface won't go up if the socket initialization fails. So we are
good to just remove the check and make it consistent.

Ondrej Zary f40bff4239 cx82310_eth: wait for firmware to become ready
When the device is powered up, some (older) firmware versions fail to work
properly if we send commands before the boot is complete (everything is OK
when the device is hot-plugged). The firmware indicates its ready status by
putting the link up.
Newer firmwares delay the first command so they don't suffer from this problem.
They also report the link being always up.

Wait for firmware to become ready (link up) before sending any commands and/or
data.

This also allows lowering CMD_TIMEOUT value to a reasonable time.

Tested with 4.1.0.9 (old) and 4.1.0.30 (new) firmware versions.

WingMan Kwok 9a391c7ba7 net: netcp: ethss: enhancement to support NetCP 1.5 ethss
NetCP 1.5 available on newer K2 SoCs such as K2E and K2L introduced 3
variants of the ethss subsystem, 9 port, 5 port and 2 port. These have
one host port towards the CPU and N external slave ports.

To customize the driver for these new ethss sub systems, multiple
compatibility strings are introduced. Currently some of parameters that
are different on different variants such as number of ALE ports, stats
modules and number of ports are defined through constants. These are now
changed to variables in gbe_priv data that get set based on the
compatibility string. This is required as there are no hardware
identification registers available to distinguish among the variants
of NetCP 1.5 ethss. However there is identification register available
to differentiate between NetCP 1.4 vs NetCP 1.5 and the same is made use
of in the code to differentiate them.

For more reading on the details of this peripheral, please refer to the
User Guide available at http://www.ti.com/lit/pdf/spruhz3

Ethss has multiple modules within the sub system
 - switch sub system
 - sgmii
 - mdio
 - switch module

NetCP driver re-uses existing davinci mdio driver. It requires to
have its own register region to map the reg space. So restructure
the code to use separate reg region for the individual modules it
manages. Use range property to define register space of NetCP and
use reg property to define individual reg spaces. So MDIO will have
its own reg space to map. This is a pre-requisite to enable MDIO
driver for NetCP.

David S. Miller 0fa74a4be4 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Conflicts:
	drivers/net/ethernet/emulex/benet/be_main.c
	net/core/sysctl_net_core.c
	net/ipv4/inet_diag.c

The be_main.c conflict resolution was really tricky.  The conflict
hunks generated by GIT were very unhelpful, to say the least.  It
split functions in half and moved them around, when the real actual
conflict only existed solely inside of one function, that being
be_map_pci_bars().

So instead, to resolve this, I checked out be_main.c from the top
of net-next, then I applied the be_main.c changes from 'net' since
the last time I merged.  And this worked beautifully.

The inet_diag.c and sysctl_net_core.c conflicts were simple
overlapping changes, and were easily to resolve.

Lendacky, Thomas 4a57ebcc2c amd-xgbe: Fix Rx coalescing reporting
The Rx coalescing value is internally converted from usecs to a value
that the hardware can use. When reporting the Rx coalescing value, this
internal value is converted back to usecs. During the conversion from
and back to usecs some rounding occurs. So, for example, when setting an
Rx usec of 30, it will be reported as 29. Fix this reporting issue by
keeping the original usec value and using that during reporting.

Lendacky, Thomas c635eaacbf amd-xgbe: Remove Tx coalescing
The Tx coalescing support in the driver was a software implementation
for something lacking in the hardware. Using hrtimers, the idea was to
trigger a timer interrupt after having queued a packet for transmit.
Unfortunately, as the timer value was lowered, the timer expired before
the hardware actually did the transmit and so it was racey and resulted
in unnecessary interrupts.

Remove the Tx coalescing support and hrtimer and replace with a Tx timer
that is used as a reclaim timer in case of inactivity.

Lendacky, Thomas 9ae5eecdba amd-xgbe-phy: Provide support for auto-negotiation timeout
Currently, there is no interrupt code that indicates auto-negotiation
has timed out. If the auto-negotiation has timed out then the start of
a new auto-negotiation will begin again with a new base page being
received. The state machine could be in a state that is not expecting
this interrupt code which results in an error during auto-negotiation.

Update the code to timestamp when the auto-negotiation starts.  Should
another page received interrupt code occur before auto-negotiation has
completed but after the auto-negotiation timeout, then reset the state
machine to allow the auto-negotiation to continue.

Hence, this patch fixes EEH error detection by replacing config reads with

Markos Chandras 87f966d97b net: ethernet: pcnet32: Setup the SRAM and NOUFLO on Am79C97{3, 5}
On a MIPS Malta board, tons of fifo underflow errors have been observed
when using u-boot as bootloader instead of YAMON. The reason for that
is that YAMON used to set the pcnet device to SRAM mode but u-boot does
not. As a result, the default Tx threshold (64 bytes) is now too small to
keep the fifo relatively used and it can result to Tx fifo underflow errors.
As a result of which, it's best to setup the SRAM on supported controllers
so we can always use the NOUFLO bit.

e.g.,

sw1p1: flags=4098<BROADCAST,MULTICAST>  mtu 1500
        ether 52:54:00:12:35:01  txqueuelen 1000  (Ethernet)

        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

where 'sw1' comes from the qemu command line -device rocker,name=sw1, and
'p1' is port 1.

Patch is adapted from Scott's phys_port_id patch.

Marcelo Ricardo Leitner 56ef9c909b vxlan: Move socket initialization to within rtnl scope
Currently, if a multicast join operation fail, the vxlan interface will
be UP but not functional, without even a log message informing the user.

Now that we can grab socket lock after already having rntl, we don't
need to defer socket creation and multicast operations. By not deferring
we can do proper error reporting to the user through ip exit code.

This patch thus removes all deferred work that vxlan had and put it back
inline. Now the socket will only be created, bound and join multicast
group when one bring the interface up, and will undo all that as soon as
one put the interface down.

As vxlan_sock_hold() is not used after this patch, it was removed too.

Marcelo Ricardo Leitner 54ff9ef36b ipv4, ipv6: kill ip_mc_{join, leave}_group and ipv6_sock_mc_{join, drop}
in favor of their inner __ ones, which doesn't grab rtnl.

As these functions need to operate on a locked socket, we can't be
grabbing rtnl by then. It's too late and doing so causes reversed
locking.

So this patch:
- move rtnl handling to callers instead while already fixing some
  reversed locking situations, like on vxlan and ipvs code.
- renames __ ones to not have the __ mark:
  __ip_mc_{join,leave}_group -> ip_mc_{join,leave}_group
  __ipv6_sock_mc_{join,drop} -> ipv6_sock_mc_{join,drop}

Brad Campbell f0b7d43c8a cc2520: Add support for CC2591 amplifier.
The TI CC2521 is an RF power amplifier that is designed to interface
with the CC2520. Conveniently, it directly interfaces with the CC2520
and does not require any pins to be connected to a
microcontroller/processor. Adding a CC2591 increases the CC2520's range,
which is useful for border router and other wall-powered applications.

Using the CC2591 with the CC2520 requires configuring the CC2520 GPIOs
that are connected to the CC2591 to correctly set the CC2591 into TX and
RX modes. Further, TI recommends that the CC2520_TXPOWER and
CC2520_AGCCTRL1 registers are set differently to maximize the CC2591's
performance. These settings are covered in TI Application Note AN065.

This patch adds an optional `amplified` field to the cc2520 entry in the
device tree. If present, the CC2520 will be configured to operate with a
CC2591.

The expected pin mapping is:
CC2520 GPIO0 --> CC2591 EN
CC2520 GPIO5 --> CC2591 PAEN

Robert Jarzmik 8d7d9cca43 Revert "smc91x: retrieve IRQ and trigger flags in a modern way"
The commit breaks the legacy platforms, ie. these not using device-tree,
and setting up the interrupt resources with a flag to activate edge
detection. The issue was found on the zylonite platform.

The reason is that zylonite uses platform resources to pass the interrupt number
and the irq flags (here IORESOURCE_IRQ_HIGHEDGE). It expects the driver to
request the irq with these flags, which in turn setups the irq as high edge
triggered.

After the patch, this was supposed to be taken care of with :
  irq_resflags = irqd_get_trigger_type(irq_get_irq_data(ndev->irq));

But irq_resflags is 0 for legacy platforms, while for example in
arch/arm/mach-pxa/zylonite.c, in struct resource smc91x_resources[] the
irq flag is specified. This breaks zylonite because the interrupt is not
setup as triggered, and hardware doesn't provide interrupts.

Alexander Aring d907c4f05c at86rf230: fix at86rf230_read_subreg succeed handling
This patch fix an issue when at86rf230_read_subreg was successful. The
function at86rf230_read_subreg will directly call regmap_read which
returns zero on successful. Nobody figured out issues yet because it was
only necessary to evaluate dvdd state while probing. This could make
trouble because the stack variable could have an random value.

The function is also used by reset the irq line before requesting irq, but
the value isn't evaluated afterwards.

Michal Schmidt a8e0c246da bnx2x: fix encapsulation features on 57710/57711
E1x chips (57710, 57711(E)) have no support for encapsulation
offload. bnx2x incorrectly advertises the support as available.

Setting of those features is conditional on "!CHIP_IS_E1x(bp)", but
the bp struct is not initialized yet at this point and consequently
any chip passes the check.
The check must use the "chip_is_e1x" local variable instead to work
correctly.

Shaohui Xie 73ee544297 net/fsl: modify xgmac_mdio for little endian SoCs
MDIO controller on little endian Socs, e.g. ls2085a is similar to the
controller on big endian Socs, but the MDIO access is little endian,
we use I/O accessor function to handle endianness, so the driver can
run on little endian Socs. A property "little-endian" is used
in DTS to indicate the MDIO is little endian, if driver probes the
property, driver will access MDIO in little endian, otherwise, driver
works in big endian by default.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2015-03-13

This series contains updates to ixgbe and ixgbevf.

Don adds additional support for X550 MAC types, which require additional
steps around enabling and disabling Rx.  Also cleans up variable type
inconsistency.

I provide a patch to allow relaxed ordering to be enabled on SPARC
architectures.  Also cleans up ixgbevf whitespace and code comments to
align the driver with networking coding standard.  Lastly cleaned up
uses of memcpy() where ether_addr_copy() could have been used.

Alex removes some dead code in the ixgbe cleanup patch.
