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

2017-03-16T02:27:23+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

card")

r8152: fix the sw rx checksum is unavailable

2017-03-16T02:27:23+00:00

[ Upstream commit 19c0f40d4fca3a47b8f784a627f0467f0138ccc8 ]

Fix the hw rx checksum is always enabled, and the user couldn't switch
it to sw rx checksum.

Note that the RTL_VER_01 only support sw rx checksum only. Besides,
the hw rx checksum for RTL_VER_02 is disabled after
commit b9a321b48af4 ("r8152: Fix broken RX checksums."). Re-enable it.

cdc_ncm: workaround for EM7455 "silent" data interface

2017-03-16T02:27:18+00:00

[ Upstream commit c086e7096170390594c425114d98172bc9aceb8a ]

Several Lenovo users have reported problems with their Sierra
Wireless EM7455 modem. The driver has loaded successfully and
the MBIM management channel has appeared to work, including
establishing a connection to the mobile network. But no frames
have been received over the data interface.

The problem affects all EM7455 and MC7455, and is assumed to
affect other modems based on the same Qualcomm chipset and
baseband firmware.

Testing narrowed the problem down to what seems to be a
firmware timing bug during initialization. Adding a short sleep
while probing is sufficient to make the problem disappear.
Experiments have shown that 1-2 ms is too little to have any
effect, while 10-20 ms is enough to reliably succeed.

catc: Use heap buffer for memory size test

commit 2d6a0e9de03ee658a9adc3bfb2f0ca55dff1e478 upstream.

Allocating USB buffers on the stack is not portable, and no longer
works on x86_64 (with VMAP_STACK enabled as per default).

commit bd9e33508c5e1eb5d807d11d7bfc52125fcdb04e upstream.

Added support for Gemalto's Cinterion PHxx WWAN interfaces
by adding QMI_FIXED_INTF with Cinterion's VID and PID.

PHxx can have:
2 RmNet Interfaces (PID 0x0082) or
1 RmNet + 1 USB Audio interface (PID 0x0083).

cdc_ncm: toggle altsetting to force reset before setup

2016-04-30T22:06:13+00:00

[ Upstream commit 48906f62c96cc2cd35753e59310cb70eb08cc6a5 ]

Some devices will silently fail setup unless they are reset first.
This is necessary even if the data interface is already in
altsetting 0, which it will be when the device is probed for the
first time.  Briefly toggling the altsetting forces a function
reset regardless of the initial state.

This fixes a setup problem observed on a number of Huawei devices,
appearing to operate in NTB-32 mode even if we explicitly set them
to NTB-16 mode.
