5b9f575163 qmi_wwan/cdc_ether: add device ID for HP lt2523 (Novatel E371) WWAN card
Another rebranded Novatel E371.  qmi_wwan should drive this device, while
cdc_ether should ignore it.  Even though the USB descriptors are plain
CDC-ETHER that USB interface is a QMI interface.  Ref commit 7fdb7846c9

This patch adds support for PID 0x1040 of Telit LE922A.

The qmi adapter requires to have DTR set for proper working,
so QMI_WWAN_QUIRK_DTR has been enabled.

9a765881bf qmi_wwan: add support for Quectel EC21 and EC25
The Quectel EC21 and EC25 need the same "set DTR" request as devices
based on the MDM9230 chipset, but has no USB3 support. Our best guess
is that the "set DTR" functionality depends on chipset and/or
baseband firmware generation. But USB3 is still an optional feature.

Since we cannot enable this unconditionally for all older devices, and
there doesn't appear to be anything we can use in the USB descriptors
to identify these chips, we are forced to use a device specific quirk
flag.

34a55d5e85 net: qmi_wwan: ignore bogus CDC Union descriptors
The CDC descriptors found on these vendor specific functions should
not be considered authoritative.  They seem to be ignored by drivers
for other systems, and the quality is therefore low.

One device (1e0e:9001) has been reported to have such a bogus union
descriptor on the QMI function, making it fail probing even if the
device id was dynamically added.  The report was not complete enough
to allow adding a device entry for this modem. But this should at
least fix the dynamic id probing problem.

32f7adf633 net: qmi_wwan: support "raw IP" mode
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.

9372514979 net: qmi_wwan: MDM9x30 specific power management
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.

7091079173 qmi_wwan: fix entry for HP lt4112 LTE/HSPA+ Gobi 4G Module
The lt4112 is a HP branded Huawei me906e modem. Like other Huawei
modems, it does not have a fixed interface to function mapping.
Instead it uses a Huawei specific scheme: functions are mapped by
subclass and protocol.

However, the HP vendor ID is used for modems from many different
manufacturers using different schemes, so we cannot apply a generic
vendor rule like we do for the Huawei vendor ID.

Replace the previous lt4112 entry pointing to an arbitrary interface
number with a device specific subclass + protocol match.

e3426ca7bc qmi_wwan: add the second QMI/network interface for Sierra Wireless MC7305/MC7355
Sierra Wireless MC7305/MC7355 with USB ID 1199:9041 also provide a
second QMI/network interface like the MC73xx with USB ID 1199:68c0 on
USB interface #10 when used in the appropriate USB configuration.
Add the corresponding QMI_FIXED_INTF entry to the qmi_wwan driver.

Please note that the second QMI/network interface is not working for
early MC73xx firmware versions like 01.08.x as the device does not
respond to QMI messages on the second /dev/cdc-wdm port.

531ad4282e qmi_wwan: Set random MAC on devices with buggy fw
Some buggy firmwares export an incorrect MAC address (00:a0:c6:00:00:00). This
makes for example checking devices for random MAC addresses tricky, and you
might end up with multiple network interfaces with the same address.

This patch tries to fix, or at least improve, the situation by setting the MAC
address of devices with this firmware bug to a random address. I tested the
patch with two devices that has this firmware bug (Huawei E398 and E392), and
network traffic worked fine after changing the address.

These devices are all clearly Sierra devices, but are also definitely
Gobi-based.  The A8 might be the MC7700/7710 and A9 is likely a MC7750.

This device provides QMI and ethernet functionality via a standard CDC
ethernet descriptor.  But when driven by cdc_ether, the QMI
functionality is unavailable because only cdc_ether can claim the USB
interface. Thus blacklist the device in cdc_ether and add its IDs to
qmi_wwan, which enables both QMI and ethernet simultaneously.

eb85569fe2 usbnet: remove generic hard_header_len check
This patch removes a generic hard_header_len check from the usbnet
module that is causing dropped packages under certain circumstances
for devices that send rx packets that cross urb boundaries.

One example is the AX88772B which occasionally send rx packets that
cross urb boundaries where the remaining partial packet is sent with
no hardware header. When the buffer with a partial packet is of less
number of octets than the value of hard_header_len the buffer is
discarded by the usbnet module.

With AX88772B this can be reproduced by using ping with a packet
size between 1965-1976.

The bug has been reported here:

https://bugzilla.kernel.org/show_bug.cgi?id=29082

This patch introduces the following changes:
- Removes the generic hard_header_len check in the rx_complete
  function in the usbnet module.
- Introduces a ETH_HLEN check for skbs that are not cloned from
  within a rx_fixup callback.
- For safety a hard_header_len check is added to each rx_fixup
  callback function that could be affected by this change.
  These extra checks could possibly be removed by someone
  who has the hardware to test.
- Removes a call to dev_kfree_skb_any() and instead utilizes the
  dev->done list to queue skbs for cleanup.

The changes place full responsibility on the rx_fixup callback
functions that clone skbs to only pass valid skbs to the
usbnet_skb_return function.
