abbe87d339 rsi: Correct RSI_NEEDED_HEADROOM in mac80211_attach.
Currently, RSI_NEEDED_HEADROOM is '80' for rsi driver, which is wrong.
As per rsi internal frame format, the RSI_NEEDED_HEADROOM shall be '84',
which is 64(dword_align) + 4(extended_desc) + 16(frame_desc).
Hence, corrected the needed headroom.

f5fbce65ab rsi: add firmware support for AP+BT dual mode
Currently, AP mode will work on only WLAN alone firmware. To give support
for AP and BT dual mode, adding firmware entry in 'struct ta_metadata'.
The firmware entry is based on what coex_mode is used in driver and coex
mode '4' for all AP+BT related functionalities. Hence, added the same.

6ae7467112 hv_netvsc: Add per-cpu ethtool stats for netvsc
This patch implements following ethtool stats fields for netvsc:
cpu<n>_tx/rx_packets/bytes
cpu<n>_vf_tx/rx_packets/bytes

Corresponding per-cpu counters already exist in current code. Exposing
these counters will help troubleshooting performance issues.

for_each_present_cpu() was used instead of for_each_possible_cpu().
for_each_possible_cpu() would create very long and useless output.
It is still being used for internal buffer, but not for ethtool
output.

There could be an overflow if cpu was added between ethtool
call netvsc_get_sset_count() and netvsc_get_ethtool_stats() and
netvsc_get_strings(). (still safe if cpu was removed)
ethtool makes these three function calls separately.
As long as we use ethtool, I can't see any clean solution.

Currently and in foreseeable short term, Hyper-V doesn't support
cpu hot-plug. Plus, ethtool is for admin use. Unlikely the admin
would perform such combo operations.

Changes in v2:
  - Remove cpp style comment
  - Resubmit after freeze

Changes in v3:
  - Reimplemented with kvmalloc instead of alloc_percpu

Changes in v4:
  - Fixed inconsistent array size
  - Use kvmalloc_array instead of kvmalloc

db251d7df4 ath10k: add debugfs file warm_hw_reset
Debugfs support to do hardware warm reset with WMI command
WMI_PDEV_PARAM_PDEV_RESET for 10.4 and 10.2.4(if wmi
service is enabled in the firmware for backward compatibility).

This change is purely for debugging purpose when hardware hangs/mutes.

This hardware reset won't affect the connectivity but there will be small
pause in data traffic. Here we are doing BB/MAC level reset and hence
whenever the BB/MAC watchdog is triggered, it does a hardware_chip_reset.
So the target will be in the active state.

Below command used to warm reset the hardware.
echo 1 > /sys/kernel/debug/ieee80211/phyX/ath10k/warm_hw_reset

tx completion not being handled, these frames are
not getting freed even after the transmission status

when the firmware sends the over-the-air tx status of
the corresponding management frames.

Handle the wmi mgmt tx completion event and free
the corresponding management frame.

673bc519c5 ath10k: disable bundle mgmt tx completion event support
The tx completion of multiple mgmt frames can be bundled
in a single event and sent by the firmware to host, if this
capability is not disabled explicitly by the host. If the host
cannot handle the bundled mgmt tx completion, this capability
support needs to be disabled in the wmi init cmd, sent to the firmware.

Add the host capability indication flag in the wmi ready command,
to let firmware know the features supported by the host driver.
This field is ignored if it is not supported by firmware.

Set the host capability indication flag(i.e. host_capab) to zero,
for disabling the support of bundle mgmt tx completion. This will
indicate the firmware to send completion event for every mgmt tx
completion, instead of bundling them together and sending in a single
event.

Since driver is devicetree-based, all device type and charateristic can be
determined by the compatible string and its data. It's unnecessary to
create another dependent function to check chip ID and then decide whether
the specific funciton is being supported on a certain device. It can be
totally replaced by the existing flag, so a cleanup is made by removing
the function and the only user, HWLRO.

====================
mlx5e-updates-2018-07-27 (Vxlan updates)

This series from Gal and Saeed provides updates to mlx5 vxlan implementation.

Gal, started with three cleanups to reflect the actual hardware vxlan state
- reflect 4789 UDP port default addition to software database
- check maximum number of vxlan  UDP ports
- cleanup an unused member in vxlan work

Then Gal provides performance optimization by replacing the
vxlan radix tree with a hash table.

Measuring mlx5e_vxlan_lookup_port execution time:

                      Radix Tree   Hash Table
     --------------- ------------ ------------
      Single Stream   161 ns       79  ns (51% improvement)
      Multi Stream    259 ns       136 ns (47% improvement)

    Measuring UDP stream packet rate, single fully utilized TX core:
    Radix Tree: 498,300 PPS
    Hash Table: 555,468 PPS (11% improvement)

Next, from Saeed, vxlan refactoring to allow sharing the vxlan table

9939a46d90 NET: stmmac: align DMA stuff to largest cache line length
As for today STMMAC_ALIGN macro (which is used to align DMA stuff)
relies on L1 line length (L1_CACHE_BYTES).
This isn't correct in case of system with several cache levels
which might have L1 cache line length smaller than L2 line. This
can lead to sharing one cache line between DMA buffer and other
data, so we can lose this data while invalidate DMA buffer before
DMA transaction.

Fix that by using SMP_CACHE_BYTES instead of L1_CACHE_BYTES for
aligning.

====================
pull-request: can-next 2018-01-16

this is a pull request for net-next/master consisting of 38 patches.

Dan Murphy's patch fixes the path to a file in the comment of the CAN
Error Message Frame Mask structure.

A patch by Colin Ian King fixes a typo in the cc770 driver.

The next patch is by me an sorts the Kconfigand Makefile entries of the
CAN-USB driver subdir alphabetically.

The patch by Jakob Unterwurzacher adds support for the UCAN USB-CAN
adapter.

YueHaibing's patch replaces a open coded skb_put()+memset() by
skb_put_zero() in the CAN-dev infrastructure.

Zhu Yi provides a patch to enable multi-queue CAN devices.

Three patches by Luc Van Oostenryck fix the return value of several
driver's xmit function, I contribute a patch for the a fourth driver.

Fabio Estevam's patch switches the flexcan driver to SPDX identifier.

Two patches by Jia-Ju Bai replace the mdelay() by a usleep_range() in
the sja1000 drivers.

The next 6 patches are by Anssi Hannula and refactor the xilinx CAN
driver and add support for the xilinx CAN FD core.

A patch by Gustavo A. R. Silva adds fallthrough annotation to the
peak_usb driver.

5 patches by Stephane Grosjean for the peak CANFD driver do some
cleanups and provide more improvements for further firmware releases.

The remaining 13 patches are by Jimmy Assarsson and the first clean up
the kvaser_usb driver, so that the later patches add support for the
Kvaser USB hydra family.

With system having a small memory (around 256MB), the state "cannot
allocate memory to refill with new buffer" is reach pretty quickly.

By this patch we changed buffer allocation method to a better handling of
