f5260f02e7 USB: cdc_ether: remove unneeded check
We already verified that "dev->udev->actconfig->extralen" was non-zero
so "len" is non-zero here as well.

2185126412 cdc_ether: Identify MBM devices by GUID in MDLM descriptor
This patch removes vid/pid for Ericsson MBM devices from the whitelist set of
devices. The MBM devices are instead identified by GUID.

In order for cdc_ether to handle these devices the GUID in the MDLM descriptor
is tested. All MBM devices currently handled by cdc_ether as well as future
CDC Ethernet MBM devices can be identified by the GUID.

This is the same solution used in Carl Nordbeck's mbm driver,
http://kerneltrap.org/mailarchive/linux-usb/2008/11/17/4141384/thread

I post this as RFC to get feedback on however cdc_ether is the correct place to
do the binding, or if it should be done in a separate driver, e.g. zaurus.

55964d72d6 cdc_ether: fix autosuspend for mbm devices
Autosuspend works until you bring the wwan interface up, then the
device does not enter autosuspend anymore.

The following patch fixes the problem by setting the .manage_power
field in the mbm_info struct to the same as in the cdc_info struct
(cdc_manager_power).

60b8675592 usbnet: Convert dev(dbg|err|warn|info) macros to netdev_<level>
These macros are too similar to the dev_<level> equivalents
but take a usbnet * argument.  Convert them to the recently
introduced netdev_<level> macros and remove the old macros.

The old macros had "\n" appended to the format string.
Add the "\n" to the converted uses.

Some existing uses of the dev<foo> macros in cdc_eem.c
probably mistakenly had trailing "\n".  No "\n" added there.

Fix net1080 this/other log message inversion.

71cc1fa9f2 cdc_ether: Partially revert "usbnet: Set link down initially ..."
Commit 37e8273cd3 ("usbnet: Set link down
initially for drivers that update link state") changed the initial link
state in cdc_ether and other drivers based on the understanding that the
devices they support generate link change interrupts.  However, this is
optional in the CDC Ethernet protocol, and two users have reported in
<http://bugzilla.kernel.org/show_bug.cgi?id=14791> that the link state
for their devices remains down.  Therefore, revert the change in
cdc_ether.

cac477e8f1 cdc_ether: add usb id for Ericsson F3507g
The Ericsson F3507g wireless broadband module provides a CDC Ethernet
compliant interface, but identifies it as a "Mobile Direct Line" CDC
subclass, thereby preventing the CDC Ethernet class driver from picking
it up.  This patch adds the device id to cdc_ether.c as a workaround.

Ericsson has provided a "class" driver for this device:
http://kerneltrap.org/mailarchive/linux-net/2008/10/28/3832094
But closer inspection of that driver reveals that it adds little more
than duplication of code from cdc_ether.c.  See also

5b2fc49991 Move USB network drivers to drivers/net/usb.
It is preferable to group drivers by usage (net, scsi, ATA, ...) than
by bus.  When reviewing drivers, the [PCI|USB|PCMCIA|...] maintainer
is probably less qualified on networking issues than a networking
maintainer.  Also, from a practical standpoint, chips often
appear on multiple buses, which is why we do not put drivers into
drivers/pci/net.
