On some devices, the internal PLL circuit occasionally provides the
wrong clock frequency after power up. The probability of failure is less
than one failure per 1000 power cycles. When the failure occurs, the
internal clock frequency is around 1/20 of the correct frequency.

For RTL8411, RTL8111G, RTL8402, RTL8105, and RTL8106, disable the feature
of entering the L2/L3 link state of the PCIe. When the nic starts the process
of entering the L2/L3 link state and the PCI reset occurs before the work
is finished, the work would be queued and continue after the next the PCI
reset occurs. This causes the device stays in L2/L3 link state, and the system
couldn't find the device.

This commit fixes the command value generated for CSUM calculation
when running in big endian mode. The Ethernet protocol ID for IP was
being unconditionally byte-swapped in the layer 3 protocol check (with
swab16), which caused the mvneta driver to not function correctly in
big endian mode. This patch byte-swaps the ID conditionally with
htons.

As reported by Maggie Mae Roxas, the mvneta driver doesn't behave
properly in 10 Mbit/s mode. This is due to a misconfiguration of the
MVNETA_GMAC_AUTONEG_CONFIG register: bit MVNETA_GMAC_CONFIG_MII_SPEED
must be set for a 100 Mbit/s speed, but cleared for a 10 Mbit/s speed,
which the driver was not properly doing. This commit adjusts that by
setting the MVNETA_GMAC_CONFIG_MII_SPEED bit only in 100 Mbit/s mode,
and relying on the fact that all the speed related bits of this
register are cleared at the beginning of the mvneta_adjust_link()
function.
This problem exists since c5aff18204da0 ("net: mvneta: driver for
Marvell Armada 370/XP network unit") which is the commit that
introduced the mvneta driver in the kernel.

It is recommended that TX work not count against the quota.
The cost of TX packet liberation is a minute percentage of what it costs to
process an RX frame. Furthermore, that SKB freeing makes memory available for
other paths in the stack.
Give the TX a larger budget and be more aggressive about cleaning up the Tx
descriptors this budget could be changed using ethtool:
$ ethtool -C eth1 tx-frames-irq <budget>

In xennet_disconnect_backend(), netif_carrier_off() was called once
per queue when it needs to only be called once.
The queue locking around the netif_carrier_off() call looked very
odd. I think they were supposed to synchronize any NAPI instances with
the expectation that no further NAPI instances would be scheduled
because of the carrier being off (see the check in
xennet_rx_interrupt()). But I can't easily tell if this works
correctly.
Instead, add a napi_synchronize() call after disabling the interrupts.
This is obviously correct as with no Rx interrupts, no further NAPI
instances will be scheduled.

The nesting of the per-queue rx_lock and tx_lock in xennet_connect()
is confusing to both humans and lockdep. The locking is safe because
this is the only place where the locks are nested in this way but
lockdep still warns.
Instead of adding the missing lockdep annotations, refactor the
locking to avoid the confusing nesting. This is still safe, because
the xenbus connection state changes are all serialized by the xenwatch
thread.

The add_vxlan_port ndo driver code was wrongly testing whether HW vxlan offloads
are supported by the device instead of checking if they are currently enabled.
This causes the driver to configure the HW parser to conduct matching for vxlan
packets but since no steering rules were set, vxlan packets are dropped on RX.
Fix that by doing the right test, as done in the del_vxlan_port ndo handler.

exit function puts the controller into reset using the socfpga reset

The RX handler of the driver has two paths switched between, depending on
the size of the frame received, as determined by SKBUFF_RX_COPYBREAK.
When a small frame is received, a new skb allocated has data space large
enough to hold the incoming frame only, and data is copied there from the
original skb whose buffer is returned to the DMA RX ring; in that case
`rx_in_place' is 0. When a large frame is received, a new skb allocated
has data space large enough to hold the largest frame possible, including
the overhead for alignment, the receive status and padding, over 4.5kiB
overall, and its buffer is placed on the DMA RX ring while the original
buffer is passed up to the network stack avoiding the need to copy data;
in that case `rx_in_place' is 1.
However the latter scenario is only possible when dynamic buffers are
used, as determined by DYNAMIC_BUFFERS, because otherwise the buffers used
for the DMA RX ring are fixed at the time the interface is brought up.
That leads to an observation that the preprocessor conditional around the
`rx_in_place' check is inverted, the check only really matters when
dynamic buffers are in use. It has gone unnoticed for many years since
support for using dynamic buffers on the DMA RX ring was introduced in
2.1.40 -- because the only problem that results is in the case where
`rx_in_place' is 1 frame data received is unnecessarily copied to the
newly-allocated buffer, before the buffer placed on the the DMA receive RX
and its contents ignored. Therefore the only symptom is some performance
loss.
Rather than flipping the condition though I decided to discard the
conditional altogether -- in the case of static buffers `rx_in_place' is
always 0 so GCC will optimise the C conditional away instead.
Tested on a few DEFPA and DEFTA boards successfully using both small and
large frames, both with DYNAMIC_BUFFERS defined and with the macro
undefined.

For the bluetooth bits, Gustavo says:
"A few fixes for 3.16. This pull request contains a NULL dereference fix,
and some security/pairing fixes."
For the iwlwifi bits, Emmanuel says:
"I have here a fix from Eliad for scheduled scan: it fixes a firmware
assertion. Arik reverts a patch I made that didn't take into account
that 3160 doesn't have UAPSD and hence, we can't assume that all
newer firmwares support the feature. Here too, the visible effect
is a firmware assertion. Along with that, we have a few fixes and
additions to the device list."
For the ath10k bits, Kalle says:
"Bartosz fixed an issue where we were not able to create 8 vdevs when
using DFS. Michal removed a false warning which was just confusing

The UniMAC CMD_SW_RESET bit is not a self-clearing bit, so we need to
assert it, wait a bit and clear it manually. As a result, umac_reset()
is updated not to return any value. The previous version of the code
simply wrote 0 to the CMD register, which would make the busy-waiting
loop exit immediately, having zero effect.
By writing 0 to the CMD register, we were clearing all bits in the CMD

The original code uses netdev->real_num_tx_queues to bookkeep number of
queues and invokes netif_set_real_num_tx_queues to set the number of
queues. However, netif_set_real_num_tx_queues doesn't allow
real_num_tx_queues to be smaller than 1, which means setting the number
to 0 will not work and real_num_tx_queues is untouched.
This is bogus when xenvif_free is invoked before any number of queues is
allocated. That function needs to iterate through all queues to free
resources. Using the wrong number of queues results in NULL pointer
dereference.
So we bookkeep the number of queues in xen-netback to solve this
problem. This fixes a regression introduced by multiqueue patchset in
3.16-rc1.
There's another bug in original code that the real number of RX queues
is never set. In current Xen multiqueue design, the number of TX queues
and RX queues are in fact the same. We need to set the numbers of TX and
RX queues to the same value.
Also remove xenvif_select_queue and leave queue selection to core
driver, as suggested by David Miller.

Pull ARM SoC fixes from Arnd Bergmann:
"A new set of bug fixes for 3.16, containing patches for seven
platforms:
at91:
- drivers/misc fix for Kconfig PWM symbol
- correction of several values in DT after conversion to CCF
- fix at91sam9261/at91sam9261ek mistake in slow crystal vs. slow RC osc
imx:
- Use GPIO for card CD/WP on imx51-babbage and eukrea-mbimxsd51,
because controller base CD/WP is not working in esdhc driver due to
runtime PM support
- A couple of random ventana gw5xxx board fixes
- Add IMX_IPUV3_CORE back to defconfig, which gets lost when moving
IPUv3 driver out of staging tree
- Fix enet/fec clock selection on imx6sl
- Fix display node on imx53-m53evk board
- A couple of Cubox-i updates from Russell, which were omitted from
the merge window due to dependency
integrator:
- fix an OF-related regression against 3.15
mvebu:
- mvebu (v7)
- Fix broken SoC ID detection
- Select ARM_CPU_SUSPEND for v7
- Remove armada38x compatible string (no users yet)
- Enable Dove SoC in mvebu_v7_defconfig
- kirkwood
- Fix phy-connection-type on GuruPlug board
qcom:
- enable gsbi driver in defconfig
- fix section mismatch warning in serial driver
samsung:
- use WFI macro in platform_do_lowpower because exynos cpuhotplug
includes a hardcoded WFI instruction and it causes compile error
in Thumb-2 mode.
- fix GIC reg sizes for exynos4 SoCs
- remove reset timer counter value during boot and resume for mct
to fix a big jump in printk timestamps
- fix pm code to check cortex-A9 for another exynos SoCs
- don't rely on firmware's secondary_cpu_start for mcpm
sti:
- Ethernet clocks were wrongly defined for STiH415/416 platforms
- STiH416 B2020 revision E DTS file name contained uppercase, change to
lowercase"

The function brcmf_usb_dlneeded() queries the device to obtain the chip
id and revision. So assigning these in bus interface before the call
resulted in chip id and revision being zero. This was introduced by:

It is observed that sometimes Tx packet is downloaded without
adding driver's txpd header. This results in firmware parsing
garbage data as packet length. Sometimes firmware is unable
to read the packet if length comes out as invalid. This stops
further traffic and timeout occurs.
The root cause is uninitialized fields in tx_info(skb->cb) of
packet used to get garbage values. In this case if
MWIFIEX_BUF_FLAG_REQUEUED_PKT flag is mistakenly set, txpd
header was skipped. This patch makes sure that tx_info is
correctly initialized to fix the problem.

Murata Manufacturing Co., Ltd is the vendor for
NTC (Negative Temperature coefficient) based Thermistors.
But, the driver extensively uses "NTC" as the vendor name.
This patch corrects the vendor name also updates the
compatibility strings according to the vendor-prefix.txt
Note: Drivers continue to support the previous compatible strings
but further addition of these compatible strings in device tree
is deprecated.
