cdc_ether: add Novatel USB551L device IDs for FLAG_WWAN

2012-05-15T17:41:43+00:00

Needs to be tagged with FLAG_WWAN, which since it has generic
descriptors, won't happen if we don't override the generic
driver info.

cdc_ether: Ignore bogus union descriptor for RNDIS devices

2012-05-06T17:11:55+00:00

Some RNDIS devices include a bogus CDC Union descriptor pointing
to non-existing interfaces.  The RNDIS code is already prepared
to handle devices without a CDC Union descriptor by hardwiring
the driver to use interfaces 0 and 1, which is correct for the
devices with the bogus descriptor as well. So we can reuse the
existing workaround.

Move Logitech Harmony 900 from cdc_ether to zaurus

2012-02-22T20:50:23+00:00

In the current kernel implementation, the Logitech Harmony 900 remote
control is matched to the cdc_ether driver through the generic
USB_CDC_SUBCLASS_MDLM entry.  However, this device appears to be of the
pseudo-MDLM (Belcarra) type, rather than the standard one.  This patch
blacklists the Harmony 900 from the cdc_ether driver and whitelists it for
the pseudo-MDLM driver in zaurus.

Merge branch 'driver-core-next' into Linux 3.2

2012-01-06T19:42:52+00:00

This resolves the conflict in the arch/arm/mach-s3c64xx/s3c6400.c file,
and it fixes the build error in the arch/x86/kernel/microcode_core.c
file, that the merge did not catch.

The microcode_core.c patch was provided by Stephen Rothwell
 who was invaluable in the merge issues involved
with the large sysdev removal process in the driver-core tree.

USB: convert drivers/net/* to use module_usb_driver()

2011-11-18T17:44:20+00:00

This converts the drivers in drivers/net/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

net/usb: Misc. fixes for the LG-VL600 LTE USB modem

2011-11-14T05:49:05+00:00

Add checking for valid magic values (needed for stability in the event
corrupted packets are received) and remove some other unneeded checks.
Also, fix flagging device as WWAN (Bugzilla bug #39952).

net/usb: mark LG VL600 LTE modem ethernet interface as WWAN

2011-05-10T22:03:50+00:00

Like other mobile broadband device ethernet interfaces, mark the LG
VL600 with the 'wwan' devtype so userspace knows it needs additional
configuration via the AT port before the interface can be used.

usbnet: use eth%d name for known ethernet devices

2011-04-02T03:12:02+00:00

The documentation for the USB ethernet devices suggests that
only some devices are supposed to use usb0 as the network interface
name instead of eth0. The logic used there, and documented in
Kconfig for CDC is that eth0 will be used when the mac address
is a globally assigned one, but usb0 is used for the locally
managed range that is typically used on point-to-point links.

Unfortunately, this has caused a lot of pain on the smsc95xx
device that is used on the popular pandaboard without an
EEPROM to store the MAC address, which causes the driver to
call random_ether_address().

Obviously, there should be a proper MAC addressed assigned to
the device, and discussions are ongoing about how to solve
this, but this patch at least makes sure that the default
interface naming gets a little saner and matches what the
user can expect based on the documentation, including for
new devices.

The approach taken here is to flag whether a device might be a
point-to-point link with the new FLAG_POINTTOPOINT setting in
the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT
and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one
of the two.  The usbnet framework only looks at the MAC address
for device naming if both flags are set, otherwise it trusts the
flag.
