Adding a device with limited QMI support. It does not support
normal QMI_WDS commands for connection management. Instead,
sending a QMI_CTL SET_INSTANCE_ID command is required to
enable the network interface:
01 0f 00 00 00 00 00 00 20 00 04 00 01 01 00 00
A number of QMI_DMS and QMI_NAS commands are also supported
for optional device management.

usbnet_disconnect() will set intfdata to NULL before calling
the minidriver unbind function. The cdc_wdm subdriver cannot
know that it is disconnecting until the qmi_wwan unbind
function has called its disconnect function. This means that
we must be able to support the cdc_wdm subdriver operating
normally while usbnet_disconnect() is running, and in
particular that intfdata may be NULL.
The only place this matters is in qmi_wwan_cdc_wdm_manage_power
which is called from cdc_wdm. Simply testing for NULL
intfdata there is sufficient to allow it to continue working
at all times.
Fixes this Oops where a cdc-wdm device was closed while the
USB device was disconnecting, causing wdm_release to call
qmi_wwan_cdc_wdm_manage_power after intfdata was set to
NULL by usbnet_disconnect:

If usbnet is resumed by remote wakeup, generally there are
some packets comming to be handled, so allocate and submit
rx URBs in usbnet_resume to avoid delays introduced by tasklet.
Otherwise, usbnet may have been runtime suspended before the
usbnet_bh is executed to schedule Rx URBs.
Without the patch, usbnet can't recieve any packets from peer
in runtime suspend state if runtime PM is enabled and
autosuspend_delay is set as zero.

Ignoring interfaces with additional descriptors is not a reliable
method for locating the correct interface on Gobi devices. There
is at least one device where this method fails:
https://bbs.archlinux.org/viewtopic.php?id=143506
The result is that the AT command port (interface #2) is hidden
from qcserial, preventing traditional serial modem usage:
[ 15.562552] qmi_wwan 4-1.6:1.0: cdc-wdm0: USB WDM device

[ 15.570372] qcserial 4-1.6:1.3: Qualcomm USB modem converter detected
[ 15.570430] usb 4-1.6: Qualcomm USB modem converter now attached to ttyUSB1
Use static interface numbers taken from the interface map in
qcserial for all Gobi devices instead:
Gobi 1K USB layout:
0: serial port (doesn't respond)
1: serial port (doesn't respond)
2: AT-capable modem port
3: QMI/net
Gobi 2K+ USB layout:
0: QMI/net
1: DM/DIAG (use libqcdm from ModemManager for communication)
2: AT-capable modem port
3: NMEA
This should be more reliable over all, and will also prevent the
noisy "probe failed" messages. The whitelisting logic is expected
to be replaced by direct interface number matching in 3.6.

or the device fails to initialise. After applying this patch and
loading the Option driver without usb-modeswitch's bind all
interfaces trick, a wwan0 net interface and /dev/cdc-wdm0 device

Change the forced interface 4 whitelist to use the generic shared
binder instead of the Gobi specific one. Certain ZTE devices
(K3520-Z & K3765-Z) don't work with the Gobi version, but function
quite happily with the generic. This has been tested with the following
devices:
K3520-Z
K3565-Z
K3765-Z
K4505-Z
It hasn't been tested with the ZTE MF820D, which is the only other
device that uses this whitelist at present. Although Bjorn doesn't
expect any problems, any testing with that device would be appreciated.

Hub-initiated LPM is not good for USB communications devices. Comms
devices should be able to tell when their link can go into a lower power
state, because they know when an incoming transmission is finished.
Ideally, these devices would slam their links into a lower power state,
using the device-initiated LPM, after finishing the last packet of their
data transfer.
If we enable the idle timeouts for the parent hubs to enable
hub-initiated LPM, we will get a lot of useless LPM packets on the bus
as the devices reject LPM transitions when they're in the middle of
receiving data. Worse, some devices might blindly accept the
hub-initiated LPM and power down their radios while they're in the
middle of receiving a transmission.
The Intel Windows folks are disabling hub-initiated LPM for all USB
communications devices under a xHCI USB 3.0 host. In order to keep
the Linux behavior as close as possible to Windows, we need to do the
same in Linux.
Set the disable_hub_initiated_lpm flag for for all USB communications
drivers. I know there aren't currently any USB 3.0 devices that
implement these class specifications, but we should be ready if they do.

Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid
recursive locking in usbnet_stop()) fixes the recursive locking
problem by releasing the skb queue lock before unlink, but may
cause skb traversing races:
- after URB is unlinked and the queue lock is released,
the refered skb and skb->next may be moved to done queue,
even be released
- in skb_queue_walk_safe, the next skb is still obtained
by next pointer of the last skb
- so maybe trigger oops or other problems
This patch extends the usage of entry->state to describe 'start_unlink'
state, so always holding the queue(rx/tx) lock to change the state if
the referd skb is in rx or tx queue because we need to know if the
refered urb has been started unlinking in unlink_urbs.
The other part of this patch is based on Huajun's patch:
always traverse from head of the tx/rx queue to get skb which is
to be unlinked but not been started unlinking.

The RNDIS protocol contains a vast number of Object ID:s (OIDs).
The current definitions had multiple definitions of these ID:s,
let's use the nicely RNDIS_*-prefixed defines from the HyperV
implementation, rename everywhere they're used, and copy+rename
the few that were missing from this list of objects.

The header file <linux/usb/rndis_host.h> used a number of #defines
that included the cpu_to_le32() macro to assure the result will be
in LE endianness. Inlining this into the code instead of using it
in the code definitions yields consolidation opportunities later
on as you will see in the following patches. The individual
drivers also used local defines - all are switched over to the
pattern of doing the conversion at the call sites instead.

Resolved the iwlwifi conflict with mainline using 3-way diff posted
by John Linville and Stephen Rothwell. In 'net' we added a bug
fix to make iwlwifi report a more accurate skb->truesize but this
conflicted with RX path changes that happened meanwhile in net-next.
In e1000e a conflict arose in the validation code for settings of
adapter->itr. 'net-next' had more sophisticated logic so that
logic was used.

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.

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.

Make smsc95xx recalculate the hard_mtu after adjusting the
hard_header_len.
Without this, usbnet adjusts the MTU down to 1488 bytes, and the host is
unable to receive standard 1500-byte frames from the device.
Inspired by same fix on cdc_eem 78fb72f7936c01d5b426c03a691eca082b03f2b9.
Tested on ARM/Beagle.
