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.

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.

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.

Many of these devices support multiple QMI/wwan ports, requiring

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,

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.
