net: cdc_ether: fix divide by 0 on bad descriptors

2017-11-26T13:50:39+00:00

commit 2cb80187ba065d7decad7c6614e35e07aec8a974 upstream.

Setting dev->hard_mtu to 0 will cause a divide error in
usbnet_probe. Protect against devices with bogus CDC Ethernet
functional descriptors by ignoring a zero wMaxSegmentSize.

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")

cdc-ether: clean packet filter upon probe

2014-07-29T19:22:15+00:00

There are devices that don't do reset all the way. So the packet filter should
be set to a sane initial value. Failure to do so leads to intermittent failures
of DHCP on some systems under some conditions.

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

2014-03-31T20:06:11+00:00

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.

r8152: disable the ECM mode

2014-03-06T01:40:24+00:00

There are known issues for switching the drivers between ECM mode and
vendor mode. The interrup transfer may become abnormal. The hardware
may have the opportunity to die if you change the configuration without
unloading the current driver first, because all the control transfers
of the current driver would fail after the command of switching the
configuration.

Although to use the ecm driver and vendor driver independently is fine,
it may have problems to change the driver from one to the other by
switching the configuration. Additionally, now the vendor mode driver
is more powerful than the ECM driver. Thus, disable the ECM mode driver,
and let r8152 to set the configuration to vendor mode and reset the
device automatically.

drivers/net: delete non-required instances of include

2014-01-16T19:53:26+00:00

None of these files are actually using any __init type directives
and hence don't need to include .   Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

This covers everything under drivers/net except for wireless, which
has been submitted separately.

r8152: ecm and vendor modes coexist

2014-01-15T02:48:54+00:00

Remove the limitation that the ecm and r8152 drivers couldn't coexist.
 - Remove the devices from the blacklist of relative drivers.
 - Remove usb_driver_set_configuration() from r8152 driver.
 - Modify the id_table of the r8152 driver for the vendor mode only.

usb: Fix FSF address in file headers

2013-12-06T17:37:55+00:00

Several files refer to an old address for the Free Software Foundation
in the file header comment.  Resolve by replacing the address with
the URL  so that we do not have to keep
updating the header comments anytime the address changes.
