This takes the MAC address for smsc75xx/smsc95xx USB network devices
from a the device tree. This is required to get a usable persistent
address on the popular beagleboard, whose hardware designers
accidentally forgot that an ethernet device really requires an a
MAC address to be functional.
The Raspberry Pi also ships smsc9514 without a serial EEPROM, stores
the MAC address in ROM accessible via VC4 firmware.
The smsc75xx and smsc95xx drivers are just two copies of the
same code, so better fix both.

The default Pegasus setup was to append the status and CRC at the end of each

usb_fill_bulk_urb() receives buffer length parameter 8 bytes larger
than what's allocated by alloc_skb(); This seems to be a problem with
older (pegasus usb-1.1) devices, which may silently return more data
than the maximal packet length.

We now have a positive report of another Huawei device needing
this quirk: The ME906s-158 (12d1:15c1). This is an m.2 form
factor modem with no obvious relationship to the E3372 (12d1:157d)
we already have a quirk entry for. This is reason enough to
believe the quirk might be necessary for any number of current
and future Huawei devices.
Applying the quirk to all Huawei devices, since it is crucial
to any device affected by the firmware bug, while the impact
on non-affected devices is negligible.
The quirk can if necessary be disabled per-device by writing
N to /sys/class/net/<iface>/cdc_ncm/ndp_to_end

This reverts commit a59f8c5b048dc938fb958c91c282c865cd845705.
There are several bugs in this new code, for example:
1) Uses sleeping locks in get_stats64, which is not allowed,
as the operation can be invoked in an atomic context.
2) Uses PM fields without CONFIG_PM or similar guards.
3) Does not synchronize HW stats when the device runtime
suspends.
Therefore this is being reverted until a correct version
is implemented.

usbnet_link_change will call schedule_work and should be
avoided if bind is failing. Otherwise we will end up with
scheduled work referring to a netdev which has gone away.
Instead of making the call conditional, we can just defer
it to usbnet_probe, using the driver_info flag made for
this purpose.

Some devices will silently fail setup unless they are reset first.
This is necessary even if the data interface is already in
altsetting 0, which it will be when the device is probed for the
first time. Briefly toggling the altsetting forces a function
reset regardless of the initial state.
This fixes a setup problem observed on a number of Huawei devices,
appearing to operate in NTB-32 mode even if we explicitly set them
to NTB-16 mode.

This avoids a harmless randconfig warning I get when USB_NET_CDC_SUBSET
is enabled, but all of the more specific drivers are not:
drivers/net/usb/cdc_subset.c:241:2: #warning You need to configure some hardware for this driver
The current behavior is clearly intentional, giving a warning when
a user picks a configuration that won't do anything good. The only
reason for even addressing this is that I'm getting close to
eliminating all 'randconfig' warnings on ARM, and this came up
a couple of times.
My workaround is to not even build the module when none of the
configurations are enable.
Alternatively we could simply remove the #warning (nothing wrong
for compile-testing), turn it into a runtime warning, or
change the Kconfig options into a menu to hide CONFIG_USB_NET_CDC_SUBSET.

When the reset_resume() is called, the flag of SELECTIVE_SUSPEND should be
cleared and reinitialize the device, whether the SELECTIVE_SUSPEND is set
or not. If reset_resume() is called, it means the power supply is cut or the
device is reset. That is, the device wouldn't be in runtime suspend state and
the reinitialization is necessary.

NCM buffer sizes are negotiated with the device independently of
the network device MTU. The RX buffers are allocated by the
usbnet framework based on the rx_urb_size value set by cdc_ncm. A
single RX buffer can hold a number of MTU sized packets.
The default usbnet change_mtu ndo only modifies rx_urb_size if it
is equal to hard_mtu. And the cdc_ncm driver will set rx_urb_size
and hard_mtu independently of each other, based on dwNtbInMaxSize
and dwNtbOutMaxSize respectively. It was therefore assumed that
usbnet_change_mtu() would never touch rx_urb_size. This failed to
consider the case where dwNtbInMaxSize and dwNtbOutMaxSize happens
to be equal.
Fix by implementing an NCM specific change_mtu ndo, modifying the
netdev MTU without touching the buffer size settings.

The CDC descriptors found on these vendor specific functions should
not be considered authoritative. They seem to be ignored by drivers
for other systems, and the quality is therefore low.
One device (1e0e:9001) has been reported to have such a bogus union
descriptor on the QMI function, making it fail probing even if the
device id was dynamically added. The report was not complete enough
to allow adding a device entry for this modem. But this should at
least fix the dynamic id probing problem.

NETIF_F_ALL_CSUM is being used as a mask).
- Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to
