If register_netdev returns failure, the dev->interrupt and
its transfer buffer should be released, so just fix it.

The transfer buffer of dev->interrupt is allocated in .probe path,
but not freed in .disconnet path, so mark the interrupt URB as
URB_FREE_BUFFER to free the buffer when the URB is destroyed.

The asix.c USB Ethernet driver avoids ending a tx transfer with a zero-
length packet by appending a four-byte padding to transfers whose length
is a multiple of maxpacket. However, the hard-coded 512 byte maxpacket
length is valid for high-speed USB only; full-speed USB uses 64 byte
packets.

The MC77xx devices can operate in two modes: "Direct IP" or "QMI",
switchable using a password protected AT command. Both product ID
and USB interface configuration will change when switched.
The "sierra_net" driver supports the "Direct IP" mode. This driver
supports the "QMI" mode.
There are also multiple possible USB interface configurations in each
mode, some providing more than one wwan interface. Like many other
devices made for Windows, different interface types are identified
using a static interface number. We define a Sierra specific
interface whitelist to support this.

Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid
recursive locking in usbnet_stop()) fixes the recursive locking
problem by releasing the skb queue lock, but it makes usb_unlink_urb
racing with defer_bh, and the URB to being unlinked may be freed before
or during calling usb_unlink_urb, so use-after-free problem may be
triggerd inside usb_unlink_urb.
The patch fixes the use-after-free problem by increasing URB
reference count with skb queue lock held before calling
usb_unlink_urb, so the URB won't be freed until return from
usb_unlink_urb.

If host is going to autosuspend function with two interfaces and
if IP packet has arrived in-between of two usbnet_suspend() callbacks,
i.e usbnet_resume() is called in-between, tx data flow is stopped.
When autosuspend timer expires and device is put to autosuspend
again, tx queue is waked up and data can be sent again.
This behavior might be repeated several times in a row.

asix_rx_fixup() is complex, and does some unnecessary memory copies (at
least on x86 where NET_IP_ALIGN is 0)
Also, it tends to provide skbs with a big truesize (4096+256 with
MTU=1500) to upper stack, so incoming trafic consume a lot of memory and
I noticed early packet drops because we hit socket rcvbuf too fast.
Switch to a different strategy, using copybreak so that we provide nice
skbs to upper stack (including the NET_SKB_PAD to avoid future head
reallocations in some paths)
With this patch, I no longer see packets drops or tcp collapses on
various tcp workload with a AX88772 adapter.

Adding the Pantech UML290 and all non-QDL Gobi device IDs from the
qcserial driver now that we have support for shared net/QMI USB
interfaces. Most of these are not yet tested with this driver, but
should be mostly identical to tested devices, except for device IDs.
Gobi devices provide several different interfaces (serial/net/other)
using the exact same class, subclass and protocol values. This driver
will only support the net/QMI function while there are other drivers
supporting other device functions. The net/QMI interface number may
also differ from device to device. It has been noted that all the
other interfaces have additional functional descriptors, so we use that
to detect the interface supported by this driver.

Some WWAN LTE/3G devices based on chipsets from Qualcomm provide
near standard CDC ECM interfaces in addition to the usual serial
interfaces. The Huawei E392/E398 are examples of such devices.
These typically cannot be fully configured using AT commands
over a serial interface. It is necessary to speak the proprietary
Qualcomm MSM Interface (QMI) protocol to the device to enable the
ethernet proxy functionality.
The devices embed the QMI protocol in CDC on the control interface,
using standard CDC commands and notifications. The do not otherwise
use CDC commands for the ethernet function. This driver does
therefore not need access to any other aspects of the control
interface than the descriptors attached to it.
Another driver, cdc-wdm, will provide userspace access to the
QMI protocol independently of this driver. To facilitate this,
this driver avoids binding to the control interface, and uses
only the associated data interface after parsing the common CDC
functional descriptors on the control interface.
You will want both the cdc-wdm and option drivers as companions to
this driver, to have full access to all interfaces and protocols
exported by the device.

defer_bh() takes the lock which is hold during unlink_urbs(). The safe
walk suggest that the skb will be removed from the list and this is done
by defer_bh() so it seems to be okay to drop the lock here.

Conflicts:
drivers/net/ethernet/sfc/rx.c
Overlapping changes in drivers/net/ethernet/sfc/rx.c, one to change
the rx_buf->is_page boolean into a set of u16 flags, and another to
adjust how ->ip_summed is initialized.

Unify return value of .ndo_set_mac_address if the given address
isn't valid. Return -EADDRNOTAVAIL as eth_mac_addr() already does
if is_valid_ether_addr() fails.

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.

The intent was to clear out the icount struct here, but we accidentally
clear stack memory instead. It probably will lead to a NULL dereference
right away.
