The call to e1000e_write_protect_nvm_ich8lan() is no longer supported by HW.
Access to these registers causes a system freeze in A step hardware and is
ignored in B step hardware. This function must not be called in hardware
newer than LPT.

When bringing down an interface netif_carrier_off() should be
one the first things we do, since this will prevent the stack
from queuing more packets to this interface.
This operation is very fast, and should make the device behave
much nicer when trying to bring down an interface under load.
Also, this would Do The Right Thing (TM) if this device has some
sort of fail-over teaming and redirect traffic to the other IF.
Move netif_carrier_off as early as possible.

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.

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.

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.

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.

With ethtool being able to control what is advertised, the advertising
field is what should be used for priming the auto-negotiation registers
and for various other checks, instead of the supported field.
Also, move the initial setting of the supported and advertising fields
into the probe function so that they are not reset each time the device
is brought up, thus allowing the user to set as desired before bringing
the device up.

Test robot noticed that we check the return of vxlan_igmp_join and leave
but inside them there was a path that it could be used initialized.
It's not really possible because those if() inside these igmp functions
would always match as we can't have sockets of other type in there, but
this way we keep the compiler happy.

pull request: bluetooth-next 2015-03-19
This wont the last 4.1 bluetooth-next pull request, but we've piled up
enough patches in less than a week that I wanted to save you from a
single huge "last-minute" pull somewhere closer to the merge window.
The main changes are:
- Simultaneous LE & BR/EDR discovery support for HW that can do it
- Complete LE OOB pairing support
- More fine-grained mgmt-command access control (normal user can now do
harmless read-only operations).
- Added RF power amplifier support in cc2520 ieee802154 driver
- Some cleanups/fixes in ieee802154 code
Please let me know if there are any issues pulling. Thanks.

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

Storing the `platform_data` struct inside of the SPI struct when using
the device tree allows for a later function to edit the content of that
struct. This patch refactors the `cc2520_get_platformat_data` function
to accept a pointer to a `cc2520_platform_data` struct and populates
the fields inside of it.

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.

Implement the phys_port_name operation. Port names are pulled from the
rocker hardware model in qemu and default to the qemu name + port id.
e.g.,
sw1p1: flags=4098<BROADCAST,MULTICAST> mtu 1500
ether 52:54:00:12:35:01 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
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.

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.

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}

Add the low-level device commands and definitions used for QP max-rate limiting.
This is done through the following elements:
- read rate-limit device caps in QUERY_DEV_CAP: number of different
rates and the min/max rates in Kbs/Mbs/Gbs units
- enhance the QP context struct to contain rate limit units and value
- allow to do run time rate-limit setting to QPs through the
update-qp firmware command
- QP rate-limiting is disallowed for VFs

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.
