For U9300

Interface 1 is used by for ADB interface in stock firmware of U9300, the

3cddfeca9f net: usb: qmi_wwan: Remove generic .ndo_get_stats64 
Commit 3e2f544dd8 ("net: get stats64 if device if driver is
configured") moved the callback to dev_get_tstats64() to net core, so,
unless the driver is doing some custom stats collection, it does not
need to set .ndo_get_stats64.

Since this driver is now relying in NETDEV_PCPU_STAT_TSTATS, then, it
doesn't need to set the dev_get_tstats64() generic .ndo_get_stats64
function pointer.

8959bf2acf net: usb: qmi_wwan: Leverage core stats allocator 
With commit 34d21de99c ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core
instead of in this driver.

With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.

Remove the allocation in the qmi_wwan driver and leverage the network
core allocation instead.

eaaacb0851 net: usb: qmi_wwan: add u-blox 0x1312 composition 
Add RmNet support for LARA-R6 01B.

The new LARA-R6 product variant identified by the "01B" string can be
configured (by AT interface) in three different USB modes:
* Default mode (Vendor ID: 0x1546 Product ID: 0x1311) with 4 serial
interfaces
* RmNet mode (Vendor ID: 0x1546 Product ID: 0x1312) with 4 serial
interfaces and 1 RmNet virtual network interface
* CDC-ECM mode (Vendor ID: 0x1546 Product ID: 0x1313) with 4 serial
interface and 1 CDC-ECM virtual network interface
The first 4 interfaces of all the 3 configurations (default, RmNet, ECM)
are the same.

In RmNet mode LARA-R6 01B exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parset/alternative functions
If 4: RMNET interface

strtobool() is the same as kstrtobool().
However, the latter is more used within the kernel.

In order to remove strtobool() and slightly simplify kstrtox.h, switch to
the other function name.

While at it, include the corresponding header file (<linux/kstrtox.h>).

057d49334c qmi_wwan: Do not call netif_rx from rx_fixup 
When the QMI_WWAN_FLAG_PASS_THROUGH is set, netif_rx() is called from
qmi_wwan_rx_fixup(). When the call to netif_rx() is successful (which is
most of the time), usbnet_skb_return() is called (from rx_process()).
usbnet_skb_return() will then call netif_rx() a second time for the same
skb.

Simplify the code and avoid the redundant netif_rx() call by changing
qmi_wwan_rx_fixup() to always return 1 when QMI_WWAN_FLAG_PASS_THROUGH
is set. We then leave it up to the existing infrastructure to call
netif_rx().

cac6fb015f usb: class: cdc-wdm: WWAN framework integration 
The WWAN framework provides a unified way to handle WWAN/modems and its
control port(s). It has initially been introduced to support MHI/PCI
modems, offering the same control protocols as the USB variants such as
MBIM, QMI, AT... The WWAN framework exposes these control protocols as
character devices, similarly to cdc-wdm, but in a bus agnostic fashion.

This change adds registration of the USB modem cdc-wdm control endpoints
to the WWAN framework as standard control ports (wwanXpY...).

Exposing cdc-wdm through WWAN framework normally maintains backward
compatibility, e.g:
    $ qmicli --device-open-qmi -d /dev/wwan0p1QMI --dms-get-ids
instead of
    $ qmicli --device-open-qmi -d /dev/cdc-wdm0 --dms-get-ids

However, some tools may rely on cdc-wdm driver/device name for device
detection. It is then safer to keep the 'legacy' cdc-wdm character
device to prevent any breakage. This is handled in this change by
API mutual exclusion, only one access method can be used at a time,
either cdc-wdm chardev or WWAN API.

Note that unknown channel types (other than MBIM, AT or MBIM) are not
registered to the WWAN framework.

This makes qmi_wwan mux implementation more similar to the

59e139cf0b net: qmi_wwan: Add pass through mode 
Pass through mode is to allow packets in MAP format to be passed
on to the stack. rmnet driver can be used to process and demultiplex
these packets.

Pass through mode can be enabled when the device is in raw ip mode only.
Conversely, raw ip mode cannot be disabled when pass through mode is
enabled.

Userspace can use pass through mode in conjunction with rmnet driver
through the following steps-

1. Enable raw ip mode on qmi_wwan device
2. Enable pass through mode on qmi_wwan device
3. Create a rmnet device with qmi_wwan device as real device using netlink

2e42338705 qmi_wwan: Increase headroom for QMAP SKBs 
When measuring the throughput (iperf3 + TCP) while routing on a
not-so-powerful device (Mediatek MT7621, 880MHz CPU), I noticed that I
achieved significantly lower speeds with QMI-based modems than for
example a USB LAN dongle. The CPU was saturated in all of my tests.

With the dongle I got ~300 Mbit/s, while I only measured ~200 Mbit/s
with the modems. All offloads, etc.  were switched off for the dongle,
and I configured the modems to use QMAP (16k aggregation). The tests
with the dongle were performed in my local (gigabit) network, while the
LTE network the modems were connected to delivers 700-800 Mbit/s.

Profiling the kernel revealed the cause of the performance difference.
In qmimux_rx_fixup(), an SKB is allocated for each packet contained in
the URB. This SKB has too little headroom, causing the check in
skb_cow() (called from ip_forward()) to fail. pskb_expand_head() is then
called and the SKB is reallocated. In the output from perf, I see that a
significant amount of time is spent in pskb_expand_head() + support
functions.

In order to ensure that the SKB has enough headroom, this commit
increases the amount of memory allocated in qmimux_rx_fixup() by
LL_MAX_HEADER. The reason for using LL_MAX_HEADER and not a more
accurate value, is that we do not know the type of the outgoing network
interface. After making this change, I achieve the same throughput with
the modems as with the dongle.

2d5c27dafe qmi_wwan: switch to core handling of rx/tx byte/packet counters 
Use netdev->tstats instead of a member of qmimux_priv for storing
a pointer to the per-cpu counters. This allows us to use core
functionality for statistics handling.
