qmi_wwan/cdc_ether: add device ID for HP lt2523 (Novatel E371) WWAN card

2017-02-15T12:59:26+00:00

[ Upstream commit 5b9f57516337b523f7466a53939aaaea7b78141b ]

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 7fdb7846c9ca

qmi_wwan/cdc_ether: move Novatel E371 (1410:9011) to qmi_wwan

2016-04-18T15:08:23+00:00

commit 7b5939ba591e9affbe4f336935b0985fd250a2b3 upstream.

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.

net/usb: add relative mii functions for r815x

2013-07-12T00:11:01+00:00

Base on cdc_ether, add the mii functions for RTL8152 and RTL8153.
The RTL8152 and RTL8153 support ECM mode which use the driver of
cdc_ether. Add the mii functions. Then, the basic PHY access is
possible.

net: cdc_ether: allow combined control and data interface

2013-07-02T08:47:41+00:00

Some Icera based Huawei modems handled by this driver are not
completely CDC ECM compliant, using the same USB interface for both
control and data. The CDC functional descriptors include a Union
naming this interface as both master and slave, so it is supportable
by relaxing the descriptor parsing in case these interfaces are
identical.

This has been tested on a Huawei K3806 and verified to add support
for that device.

qmi_wwan/cdc_ether: let qmi_wwan handle the Huawei E1820

2013-06-11T09:43:22+00:00

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.
