A change in MCFW behaviour means that the net driver must update its record
of the warm_boot_count by reading it from the ER_DZ_BIU_MC_SFT_STATUS
register.

On v4.6.x MCFW the global boot count was incremented when some functions
needed to be reset to enable multicast chaining, so all functions saw the
same value.  In that case, the driver needed to increment its
warm_boot_count when other functions were reset, to avoid noticing it later
and then trying to reset itself to recover unnecessarily.

With v4.7+ MCFW, the boot count in firmware doesn't change as that is
unnecessary since the PFs that have been reset will each receive an MC
reboot notification.  In that case, the driver re-reads the unchanged
value.

net: qmi_wwan: MDM9x30 support

We add new device IDs all the time, often without any testing on
actual hardware. This is usually OK as long as the device is similar
to already supported devices, using the same chipset and firmware
basis.  But the Sierra Wireless MC7455 is an example of a new chipset
generation. Adding it based on assumed similarity with its ancestors
proved too optimistic.

This series adds the missing bits and pieces necessary to support LTE
Advanced modems based on the Qualcomm MDM9x30 chipset. A big thanks to
Sierra Wireless for providing MC7455 samples for testing

The most important change is the "raw-ip" support. The series also
adds a necessary control request, removes an unsupported device ID,
and adds a driver specific entry in MAINTAINERS.

A few random notes about "raw-ip":

"I rather have these all running in raw IP mode. The 802.3 framing is
utterly stupid." - Marcel Holtmann in Jan 2012 [1]

Marcel was right.  I should have listened to him. What more can I say?

The 802.3 framing has provided a steady supply of firmware bugs for
many years. We've added driver workarounds for many of these, but
there are still known bugs where the workaround is so yucky that we
have refused to apply it. But all that is over now.  The latest
generation Qualcomm chips no longer supports 802.3 framing at all.

I had two open questions regarding the "raw-ip" userspace API:

1) Should we continue faking an ethernet device, even if we don't use
   the L2 headers on the USB link anymore?

   There was a vote in favour of the "headerless" device. This is the
   honest representation of the hardware/firmware interface.

2) What input should the driver base its framing on?

   Snooping or directly manipulating QMI is considered out of the
   question. We delegated all QMI handling to userspace from the
   beginning.

   We have so far required userspace to configure the firmware for
   "802.3" framing, or fail if that proved impossible.  This
   requirement is now changed.  Userspace must now inform the driver
   if it negotiates "raw-ip" framing.  Two alternative interfaces were
   proposed:
    - ethtool private driver flag, or
    - sysfs file

   The NetworkManager/ModemManager developers were in favour of the
   sysfs alternative.

These questions (or any other you migh have :) are of course still
open.  This patch set presents the solutions I currently prefer,
considering the above.

All comments are appreciated, even simple '+1' ones.

QMI wwan devices have traditionally emulated ethernet devices
by default. But they have always had the capability of operating
without any L2 header at all, transmitting and receiving "raw"
IP packets over the USB link.  This firmware feature used to be
configurable through the QMI management protocol.

Traditionally there was no way to verify the firmware mode
without attempting to change it.  And the firmware would often
disallow changes anyway, i.e. due to a session already being
established.  In some cases, this could be a hidden firmware
internal session, completely outside host control.  For these
reasons, sticking with the "well known" default mode was safest.

But newer generations of QMI hardware and firmware have moved
towards defaulting to "raw IP" mode instead, followed by an
increasing number of bugs in the already buggy "802.3" firmware
implementation. At the same time, the QMI management protocol
gained the ability to detect the current mode.  This has enabled
the userspace QMI management application to verify the current
firmware mode without trying to modify it.

Following this development, the latest QMI hardware and firmware
(the MDM9x30 generation) has dropped support for "802.3" mode
entirely. Support for "raw IP" framing in the driver is therefore
necessary for these devices, and to a certain degree to work
around problems with the previous generation,

This patch adds support for "raw IP" framing for QMI devices,
changing the netdev from an ethernet device to an ARPHRD_NONE
p-t-p device when "raw IP" framing is enabled.

The firmware setup is fully delegated to the QMI userspace
management application, through simple tunneling of the QMI
protocol. The driver will therefore not know which mode has been
"negotiated" between firmware and userspace. Allowing userspace
to inform the driver of the result through a sysfs switch is
considered a better alternative than to change the well established
clean delegation of firmware management to userspace.

MDM9x30 based modems appear to go into a deeper sleep when
suspended without "Remote Wakeup" enabled.  The QMI interface
will not respond unless a "set DTR" control request is sent
on resume. The effect is similar to a QMI_CTL SYNC request,
resetting (some of) the firmware state.

We allow userspace sessions to span multiple character device
open/close sequences.  This means that userspace can depend
on firmware state while both the netdev and the character
device are closed.  We have disabled "needs_remote_wakeup" at
this point to allow devices without remote wakeup support to
be auto-suspended.

To make sure the MDM9x30 keeps firmware state, we need to
keep "needs_remote_wakeup" always set. We also need to
issue a "set DTR" request to enable the QMI interface.

net:hns: Add support of Hip06 SoC to the Hislicon Network Subsystem

This PATCH V7 addresses the TAB formatting comments by
Sergei Shtylyov. Missing TABs at some other palces have
also been corrected.

PATCH V6:
This addresses the review comments provided by
David Miller over the existing use of ENABLE/DISABLE
hash defines with the code. These hash defines are doing
a similar job as implicit type bool would do. So these are
kind of duplicate and are redundant.

PATCH V5:
This PATCH addresses the review comments by Yuval Mintz
 <Yuval.Mintz@qlogic.com>. This rework of comments are basically
 related to:
 1) styling of the code,
 2) RSS default Key initiailization related code
 3) redundant code removal

PATCH V4:
This addresses the review comment provided by
Sergei Shtylyov. The changelog of every patch has also
been modified.

PATCH V3:
 Addresses the review comment floated by David Miller

PATCH V2:
1) Bug Fixes and Clean-up: Internally identified
2) Addresses internal review comments by Kenneth Lee and
   by Huang Daode
3) Addresses the review comment from "Yisen.Zhuang(Zhuangyuzeng)"
4) Adds fix from Fengguang Wu for an error generated from
   "kbuild test robot" from Intel
5) Ethtool support for TSO set option from Lisheng

PATCH V1:
Adds initial support of Hip06 SoC with below changes:
This patch-set adds support of new Hisilicon Hip06 SoC to the existing
(already part of net-next) HNS ethernet driver for Hip05 SoC. Hip06 is
a multi-core SoC and is a derivative of Hip05 SoC with lots of new
hardware featres supported like RSS, TSO, hardware VLAN assist etc.

The changes in the driver are mainly due to following:
 1) changes in the DMA descriptor provided by the Hip06 ethernet
    hardware. These changes need to co-exist with already present
    Hip05 DMA descriptor and its operating functions. The decision
    to choose the correct type of DMA descriptor is taken dynamically
    depending upon the version of the hardware (i.e. V1/hip05 or
    V2/hip06, see already existing hisilicon-hns-nic.txt binding file
    for the detailed description version and naming).
 2) To support new features added to the Hip06 ethernet hardware:
    a. RSS (Receive Side Scaling)
    b. TSO (TCP Segment Offload)
    c. Hardware VLAN support (currently we are initializing hardware
       to not assist in stripping the vlan tag at hardware level.
       Proper support of this feature and ethtool would come after
       these patches have been accepted)

Kindly note that, this patchset has been based on latest net-next.

Call bnxt_cfg_rx_mode() in bnxt_init_chip() to setup uc_list and
mc_list mac address filters.  Before the patch, uc_list is not
setup again after chip reset (such as ethtool ring size change)
and macvlans don't work any more after that.

Modify bnxt_cfg_rx_mode() to return error codes appropriately so
that the init chip sequence can detect any failures.
