The conflicts are of two varieties:

1) Conflicts with Joe Perches's 'extern' removal from header file
   function declarations.  Usually it's an argument signature change
   or a function being added/removed.  The resolutions are trivial.

2) Some overlapping changes in qmi_wwan.c and be.h, one commit adds
   a new value, another changes an existing value.  That sort of
   thing.

Bjørn Mork 0470667caa net: qmi_wwan: add new Qualcomm devices
Adding the device list from the Windows driver description files
included with a new Qualcomm MDM9615 based device, "Alcatel-sbell
ASB TL131 TDD LTE", from China Mobile.  This device is tested
and verified to work.  The others are assumed to work based on
using the same Windows driver.

Many of these devices support multiple QMI/wwan ports, requiring
multiple interface matching entries.  All devices are composite,
providing a mix of one or more serial, storage or Android Debug
Brigde functions in addition to the wwan function.

This device list included an update of one previously known device,
which was incorrectly assumed to have a Gobi 2K layout.  This is
corrected.

Bjørn Mork c2020be3c3 qmi_wwan/cdc_ether: let qmi_wwan handle the Huawei E1820
Another QMI speaking Qualcomm based device, which should be
driven by qmi_wwan, while cdc_ether should ignore it.

Like on other Huawei devices, the wwan function can appear
either as a single vendor specific interface or as a CDC ECM
class function using separate control and data interfaces.
The ECM control interface protocol is 0xff, likely in an
attempt to indicate that vendor specific management is
required.

In addition to the near standard CDC class, Huawei also add
vendor specific AT management commands to their firmwares.
This is probably an attempt to support non-Windows systems
using standard class drivers.  Unfortunately, this part of
the firmware is often buggy.  Linux is much better off using
whatever native vendor specific management protocol the
device offers, and Windows uses, whenever possible. This
means QMI in the case of Qualcomm based devices.

The E1820 has been verified to work fine with QMI.

Matching on interface number is necessary to distiguish the
wwan function from serial functions in the single interface
mode, as both function types will have class/subclass/function
set to ff/ff/ff.

The control interface number does not change in CDC ECM mode,
so the interface number matching rule is sufficient to handle
both modes.  The cdc_ether blacklist entry is only relevant in
CDC ECM mode, but using a similar interface number based rule
helps document this as a transfer from one driver to another.

Other Huawei 02/06/ff devices are left with the cdc_ether driver
because we do not know whether they are based on Qualcomm chips.
The Huawei specific AT command management is known to be somewhat
hardware independent, and their usage of these class codes may
also be independent of the modem hardware.

Bjørn Mork cc6ba5fdaa net: qmi_wwan: prevent duplicate mac address on link (firmware bug workaround)
We normally trust and use the CDC functional descriptors provided by a
number of devices.  But some of these will erroneously list the address
reserved for the device end of the link.  Attempting to use this on
both the device and host side will naturally not work.

Work around this bug by ignoring the functional descriptor and assign a
random address instead in this case.

The bogus address is always the same, and matches the address
suggested by many devices as a default address.  It is likely a
hardcoded firmware default.

The circumstances where this bug has been observed indicates that
the trigger is related to timing or some other factor the host
cannot control. Repeating the exact same configuration sequence
that caused it to trigger once, will not necessarily cause it to
trigger the next time. Reproducing the bug is therefore difficult.
This opens up a possibility that the bug is more common than we can
confirm, because affected devices often will work properly again
after a reset.  A procedure most users are likely to try out before
reporting a bug.

Unconditionally rewriting the destination address if the first digit
of the received packet is 0, is considered an acceptable compromise
since we already have to inspect this digit.  The simplification will
cause unnecessary rewrites if the real address starts with 0, but this
is still better than adding additional tests for this particular case.

Bjørn Mork 6ff509af38 net: qmi_wwan: fixup missing ethernet header (firmware bug workaround)
A number of LTE devices from different vendors all suffer from the
same firmware bug: Most of the packets received from the device while
it is attached to a LTE network will not have an ethernet header. The
devices work as expected when attached to 2G or 3G networks, sending
an ethernet header with all packets.

This driver is not aware of which network the modem attached to, and
even if it were there are still some packet types which are always
received with the header intact.

All devices supported by this driver have severely limited
networking capabilities:
 - can only transmit IPv4, IPv6 and possibly ARP
 - can only support a single host hardware address at any time
 - will only do point-to-point communcation with the host

Because of this, we are able to reliably identify any bogus raw IP
packets by simply looking at the 4 IP version bits.  All we need to
do is to avoid 4 or 6 in the first digit of the mac address.  This
workaround ensures this, and fix up the received packets as necessary.

Given the distribution of the bug, it is believed that the source is
the chipset vendor.  The devices which are verified to be affected are:
 Huawei E392u-12 (Qualcomm MDM9200)
 Pantech UML290  (Qualcomm MDM9600)
 Novatel USB551L (Qualcomm MDM9600)
 Novatel E362    (Qualcomm MDM9600)

It is believed that the bug depend on firmware revision, which means
that possibly all devices based on the above mentioned chipset may be
affected if we consider all available firmware revisions.

The information about affected devices and versions is likely
incomplete.  As the additional overhead for packets not needing this
fixup is very small, it is considered acceptable to apply the
workaround to all devices handled by this driver.

Bjørn Mork b701f16dd4 net: qmi_wwan: set correct altsetting for Gobi 1K devices
commit bd877e4 ("net: qmi_wwan: use a single bind function for
all device types") made Gobi 1K devices fail probing.

Using the number of endpoints in the default altsetting to decide
whether the function use one or two interfaces is wrong.  Other
altsettings may provide more endpoints.

With Gobi 1K devices, USB interface #3's altsetting is 0 by default, but
altsetting 0 only provides one interrupt endpoint and is not sufficent
for QMI.  Altsetting 1 provides all 3 endpoints required for qmi_wwan
and works with QMI. Gobi 1K layout for intf#3 is:

    Interface Descriptor:  255/255/255
      bInterfaceNumber        3
      bAlternateSetting       0
      Endpoint Descriptor:  Interrupt IN
    Interface Descriptor:  255/255/255
      bInterfaceNumber        3
      bAlternateSetting       1
      Endpoint Descriptor:  Interrupt IN
      Endpoint Descriptor:  Bulk IN
      Endpoint Descriptor:  Bulk OUT

Prior to commit bd877e4, we would call usbnet_get_endpoints
before giving up finding enough endpoints. Removing the early
endpoint number test and the strict functional descriptor
requirement allow qmi_wwan_bind to continue until
usbnet_get_endpoints has made the final attempt to collect
endpoints.  This restores the behaviour from before commit
bd877e4 without losing the added benefit of using a single bind
function.

The driver has always required a CDC Union functional descriptor
for two-interface functions. Using the existence of this
descriptor to detect two-interface functions is the logically
correct method.

Whereas on the 'net-next' side we are calculating the UID and GID from

Bjørn Mork 8624dd2a3e net: qmi_wwan: call subdriver with control intf only
This fixes a hang on suspend due to calling wdm_suspend on
the unregistered data interface. The hang should have been
a NULL pointer reference had it not been for a logic error
in the cdc_wdm code.

  commit 230718bd net: qmi_wwan: bind to both control and data interface

changed qmi_wwan to use cdc_wdm as a subdriver for devices with
a two-interface QMI/wwan function.  The commit failed to update
qmi_wwan_suspend and qmi_wwan_resume, which were written to handle
either a single combined interface function, or no subdriver at all.

The result was that we called into the subdriver both when the
control interface was suspended and when the data interface was
suspended.  Calling the subdriver suspend function with an
unregistered interface is not supported and will make the
subdriver bug out.

Bjørn Mork 3ee2403739 net: qmi_wwan: increase max QMI message size to 4096
QMI requests exceeding 1500 bytes are possible and
device firmware does not handle fragmented messages
very well.  It is therefore necessary to increase
the maximum message size from the current 512 bytes.

The protocol message size limit is not documented
in any publicly known source, but the out of tree
driver from CodeAurora use 4 kB.  This is therefore
chosen as the new arbitrary default until the real
limit is known.

This should allow any QMI message to be transmitted
without fragmentation, fixing known issues with GPS
assistance data upload.

Bjørn Mork 10cbc1d97a net: qmi_wwan: new devices: UML290 and K5006-Z
Newer firmware versions for the Pantech UML290 use a different
subclass ID.  The Windows driver match on both IDs, so we do
that as well.

The ZTE (Vodafone) K5006-Z is a new device.
