This patch removes an unneccesary 1ms mdelay in the HS200 tuning
loop, called 40 times per retuning. Currently this causes a latency
of >40ms on any emmc accesses triggering wake from runtime PM,
which can occur for a significant portion of reads on a mostly idle system.
The delay is left in place for SD Cards, which use
MMC_SEND_TUNING_BLOCK rather than MMC_SEND_TUNING_BLOCK_HS200.
I'm not able to find evidence that this is required for SD in the
specs I have access to, however this delay has been present from
initial checkin for SD so I have preserved the original behavior for
compatibility.
This has been verified to fix observed glitching on local audio
playback and recording on apps with inbuilt assumptions on storage
latency.

If a struct contains 64-bit fields, it is aligned on 64-bit boundaries
within containing structs in 64-bit compilations. This is the case with
struct v4l2_window, which contains pointers and is embedded into struct
v4l2_format, and that one is embedded into struct v4l2_create_buffers.
Unlike some other structs, used as a part of the kernel ABI as ioctl()
arguments, that are packed, these structs aren't packed. This isn't a
problem per se, but the ioctl-compat code for VIDIOC_CREATE_BUFS contains
a bug, that triggers in such 64-bit builds. That code wrongly assumes,
that in struct v4l2_create_buffers, struct v4l2_format immediately follows
the __u32 memory field, which in fact isn't the case. This bug wasn't
visible until now, because until recently hardly any applications used
this ioctl() and mostly embedded 32-bit only drivers implemented it. This
is changing now with addition of this ioctl() to some USB drivers, e.g.
UVC. This patch fixes the bug by copying parts of struct
v4l2_create_buffers separately.

When I was converting the driver to the managed device API, only devm_kzalloc()
was available for memory allocation, so I had to use it, despite zeroing out the
PHY IRQ array right before initializing all its entries to PHY_POLL was quite
stupid. Now that devm_kmalloc_array() has become available, we can avoid the
needless zeroing out...

If any TSO fragment hits hardware bug conditions (e.g. 4G boundary), the
driver will workaround by calling skb_copy() to copy to a linear SKB. Users
have reported page allocation failures as the TSO packet can be up to 64K.
Copying such a large packet is also very inefficient. We fix this by using
existing tg3_tso_bug() to transmit the packet using GSO.

tg3 uses GSO as workaround if the hardware cannot perform TSO on certain
packets. We should not modify the ip header fields if we do GSO on the
packet. It happens to work by accident because GSO recalculates the IP
checksum and IP total length.

The NCM class match in the cdc_mbim driver is confusing and
cause unexpected behaviour. The USB core guarantees that a
USB interface is in altsetting 0 when probing starts. This
means that devices implementing a NCM 1.0 backwards
compatible MBIM function (a "NCM/MBIM function") always hit
the NCM entry in the cdc_mbim driver match table. Such
functions will never match any of the MBIM entries.
This causes unexpeced behaviour for cases where the NCM and
MBIM entries are differet, which is currently the case for
all except Ericsson devices.
Improve the probing of NCM/MBIM functions by looking up the
device again in the cdc_mbim match table after switching to
the MBIM identity.
The shared altsetting selection is updated to better
accommodate the new probing logic, returning the preferred
altsetting for the control interface instead of the data
interface. The control interface altsetting update is moved
to the cdc_mbim driver. It is never necessary to change the
control interface altsetting for NCM.

DSS VLANs are pseudo network interfaces representing arbitrary
data streams, and specifically not IP. Preventing spurious IP
packets can sometimes be a hassle. The kernel will for example
send an IPv6 Router Solicit when the interface is brought up
unless the user has been careful enough to disable IPv6 first.
Such packets forwared to a MBIM DSS session will look like
spurious noise to the device, and can cause it to log an error
or even malfunction.
Drop all IP packets on the designated DSS VLANs to prevent such
unwanted spurious transmissions.

The cdc_mbim driver maps 802.1q VLANs to MBIM IP and DSS
sessions. MBIM IP session 0 is handled as an exception and
is mapped to untagged frames.
This patch adds optional support for remapping MBIM IP
session 0 to 802.1q VLAN ID 4094 instead. The default
behaviour is not changed. The new behaviour is triggered
by adding a link for this previously unsupported VLAN.
The untagged mapping was chosen initially to support the
assumed most common use case: Most current MBIM devices only
support a single IP session (i.e. session 0 only), and using
untagged frames lets the users completely ignore the
additonal complexity of the multiplexing layer.
But when the multiplexing features of MBIM are used, then
this netdev gets a double meaning: It becomes the master
interface for all the VLAN subdevs the additional sessions
are mapped to, while still serving as the untagged IP
interface for session 0.
This can be problematic, especially when using Device Service
Streams (DSS), as have become apparent recently with the
availability of devices with real DSS support. Some use cases
need to e.g set a MTU which is higher than allowed for IP
Session 0. The dual role also leads to the situation where
the IP Session 0 interface cannot be taken down without
breaking unrelated IP or DSS sessions - a devastating side
effect which applications managing a simple IP session cannot
be expected to be aware of. A typical DHCP client will assume
that it should bring the interface down after releasing the
IP lease.
These problems can be avoided by tagging IP session 0 packets
too, making this session similar to all other multiplexed
sessions. This redefines the main netdev as an upper master
interface only.

FWS is always queuing frames and using a worker for de-queueing,
this is not always efficient for all bus layer. For example SDIO
has an internal queue and worker making the queueing of FWS
unnecessary. Make it possible to bypass the worker if fws mode
is none using a bus interface configuration. For USB bus layer
