This is a RNDIS function driver, extracted from the all-in-one
Ethernet gadget driver.
Lightly tested ... there seems to be a pre-existing problem when
talking to Windows XP SP2, not quite sure what's up with that yet.

This is a "CDC Ethernet" (ECM) function driver, extracted from the
all-in-one Ethernet gadget driver.
This is a good example of how to implement interface altsettings.
In fact it's currently the only such example in the gadget stack,
pending addition of OBEX support.

Abstract the peripheral side Ethernet-over-USB link layer code from
the all-in-one Ethernet gadget driver into a component that can be
called by various functions, so the various flavors can be split
apart and selectively reused.
A notable difference from the approach taken with the serial link
layer code (beyond talking to NET not TTY) is that because of the
initialization requirements, this only supports one network link.
(And one set of Ethernet link addresses.)
That is, each configuration may have only one instance of a network
function. This doesn't change behavior; the current code has that
same restriction. If you want multiple logical links, that can
easily be done using network layer tools.

Some cleanup to the RNDIS code:
- Minor bugfix: rndis_unit() is supposed to put the link into the
RNDIS_UNINITIALIZED state, which does not mean "unused". There's
a separate method to stop using the link. (Bug doesn't affect
anything right now because of how the code is used.)
- Reduce coupling between RNDIS code and its user(s), in preparation
for updates in that code:
* Decouple RNDIS_RESPONSE_AVAILABLE notifications from net_device
by passing just a void* handle. (Also, remove the unused return
value of the notification callback.)
* When it needs a copy of net_device stats, just ask for it
- Remove unused/untested code backing various never-used OIDs:
* RNDIS_PM, RNDIS_WAKEUP ... "should" get implemented, but the
relevant docs were unclear, ambguous, and incomplete. Someone
with access to the Hidden Gospels (maybe in the EU?) might be
able to figure out what this should do.
* RNDIS_OPTIONAL_STATS ... as the name suggests, optional. Never
implemented in part because not all the semantics were clear.
* OID_GEN_RNDIS_CONFIG_PARAMETER, which has been #if 0 forever.
- A few small whitespace fixes
Plus switch the VERBOSE symbol over to the newer VERBOSE_DEBUG style.
There should be no functional changes because of this patch; it's a
net source code shrink (because of the dead/unused code removal) and
a small object code shrink (a couple hundred bytes on ARMv5).

Split out CDC ACM parts of "gadget serial" to a "function driver".
Some key structural differences from the previous ACM support, shared
with with the generic serial function (next patch):
- As a function driver, it can be combined with other functions.
One gadget configuration could offer both serial and network
links, as an example.
- One serial port can be exposed in multiple configurations;
the /dev/ttyGS0 node could be exposed regardless of which
config the host selected.
- One configuration can expose multiple serial ports, such as
ttyGS0, ttyGS1, ttyGS2, and ttyGS3.
This code should be a lot easier to understand than the previous
all-in-one-big-file version of the driver.

Update Gadget Zero to use the more modular versions of the loopback
and source/sink configuration drivers which build on the new gadget
framework code.
The core code is a LOT simpler, and it should be much easier now to
understand how the parts fit together. The conversion is an overall
source shrink in terms of this gadget, since it uses more midlayer
support. However, it's an overall increase in object size because
there's less sharing between the two configurations (improves code
clarity) and because the midlayer is a bit more functional than this
driver actually needs.

Neither this, nor its sibling "loopback" configuration, is a function

driver wouldn't know how to deal with that!) However the code becomes
simpler because of this conversion, so it's a net win.

Add <linux/usb/composite.h> interfaces for composite gadget drivers, and
basic implementation support behind it:
- struct usb_function ... groups one or more interfaces into a function
managed as one unit within a configuration, to which it's added by
usb_add_function().
- struct usb_configuration ... groups one or more such functions into
a configuration managed as one unit by a driver, to which it's added
by usb_add_config(). These operate at either high or full/low speeds
and at a given bMaxPower.
- struct usb_composite_driver ... groups one or more such configurations
into a gadget driver, which may be registered or unregistered.
- struct usb_composite_dev ... a usb_composite_driver manages this; it
wraps the usb_gadget exposed by the controller driver.
This also includes some basic kerneldoc.
How to use it (the short version): provide a usb_composite_driver with a
bind() that calls usb_add_config() for each of the needed configurations.
The configurations in turn have bind() calls, which will usb_add_function()
for each function required. Each function's bind() allocates resources
needed to perform its tasks, like endpoints; sometimes configurations will
allocate resources too.
Separate patches will convert most gadget drivers to this infrastructure.

Define three new descriptor manipulation utilities, for use when
setting up functions that may have multiple instances:
usb_copy_descriptors() to copy a vector of descriptors
usb_free_descriptors() to free the copy
usb_find_endpoint() to find a copied version
These will be used as follows. Functions will continue to have static
tables of descriptors they update, now used as __initdata templates.
When a function creates a new instance, it patches those tables with
relevant interface and string IDs, plus endpoint assignments. Then it
copies those morphed descriptors, associates the copies with the new
function instance, and records the endpoint descriptors to use when
activating the endpoints. When initialization is done, only the copies
remain in memory. The copies are freed on driver removal.
This ensures that each instance has descriptors which hold the right
instance-specific data. Two instances in the same configuration will
obviously never share the same interface IDs or use the same endpoints.
Instances in different configurations won't do so either, which means
this is slightly less memory-efficient in some cases.
This also includes a bugfix to the epautoconf code that shows up with
this usage model. It must replace the previous endpoint number when
updating the template descriptors, not just mask in a few more bits.

Teach "gadget serial" to use the new abstracted (and bugfixed) TTY glue,
and remove all the orignal tangled-up code. Update the documentation
accordingly. This is a net object code shrink and cleanup; it should
make it a lot easier to see how the TTY glue should accomodate updates
to the TTY layer, be bugfixed, etc.
Notable behavior changes include: it can now support getty even when
there's no USB connection; it fits properly into the mdev/udev world;
and RX handling is better (throttling works, and low latency).
Configurations with scripts setting up the /dev/ttygserial device node
(with "experimental" major number) may want to change that to be a
symlink pointing to the /dev/ttyGS0 file, as a migration aid; else,
just switch entirely over to mdev/udev.

This abstracts the "gadget serial" driver TTY glue into a separate
component, cleaning it up and disentangling it from connection state.
It also changed some behaviors for the better:
- Stops using "experimental" major #127, and switches over to
having the TTY layer allocate the dev_t numbers.
- Provides /sys/class/tty/ttyGS* nodes, thus mdev/udev support.
(Note "mdev" hotplug bug in Busybox v1.7.2: /dev/ttyGS0 will
be a *block* device without CONFIG_SYSFS_DEPRECATED_V2.)
- The tty nodes no longer reject opens when there's no host.
Now they can support normal getty configs in /etc/inttab...
- Now implements RX throttling. When the line discipline says
it doesn't want any more data, only packets in flight will be
delivered (currently, max 1K/8K at full/high speeds) until it
unthrottles the data.
- Supports low_latency. This is a good policy for all USB serial
adapters, since it eliminates scheduler overhead on RX paths.
This also includes much cleanup including better comments, fixing
memory leaks and other bugs (including some locking fixes), messaging
cleanup, and an interface audit and tightening. This added up to a
significant object code shrinkage, on the order of 20% (!) depending
on CPU and compiler.
A separate patch actually kicks in this new code, using the functions
declared in this new header, and removes the previous glue.

This patch (as1092) implements "soft" unbinding for usb-storage. When
the disconnect routine is called, all commands and reset delays are
allowed to complete normally until after scsi_remove_host() returns.
This means that the commands needed for an orderly shutdown will be
sent through to the device.
Unlike before, the driver will now execute every command that it
accepts. Hence there's no need for special code to catch unexecuted
commands and fail them.
The new sequence of events when disconnect runs goes as follows:
If the device is truly unplugged, set the DISCONNECTING
flag so we won't try to access it any more.
If the SCSI-scanning thread hasn't started up yet, prevent
it from doing anything by setting the new DONT_SCAN flag.
Then wake it up and wait for it to terminate.
Remove the SCSI host. This unbinds the upper-level drivers,
doing an orderly shutdown. Commands sent to quiesce the
device will be transmitted normally, unless the device is
unplugged.
Set the DISCONNECTING flag so that we won't accept any new
commands that might get submitted (there aren't supposed to be
any) and we won't try to access the device for resets.
Tell the control thread to exit by waking it up with no
pending command, and wait for it to terminate.
Go on to do all the other normal stuff: releasing resources,
freeing memory, and so on.

This patch (as1091) changes the way usbcore handles interface
unbinding. If the interface's driver supports "soft" unbinding (a new
flag in the driver structure) then in-flight URBs are not cancelled
and endpoints are not disabled. Instead the driver is allowed to
continue communicating with the device (although of course it should
stop before its disconnect routine returns).
The purpose of this change is to allow drivers to do a clean shutdown
when they get unbound from a device that is still plugged in. Killing
all the URBs and disabling the endpoints before calling the driver's
disconnect method doesn't give the driver any control over what
happens, and it can leave devices in indeterminate states. For
example, when usb-storage unbinds it doesn't want to stop while in the
middle of transmitting a SCSI command.
The soft_unbind flag is added because in the past, a number of drivers
have experienced problems related to ongoing I/O after their disconnect
routine returned. Hence "soft" unbinding is made available only to
drivers that claim to support it.
The patch also replaces "interface_to_usbdev(intf)" with "udev" in a
couple of places, a minor simplification.

This patch (as1089) separates out the dynamic atomic bitflags and the
static bitfields in usb-storage. Until now the two sorts of flags
have been sharing the same word; this has always been awkward.
To help prevent possible confusion, the two new fields each have a
different name from the original. us->fflags contains the fixed
bitfields (mostly taken from the USB ID table in unusual_devs.h), and
us->dflags contains the dynamic atomic bitflags (used with set_bit,
test_bit, and so on).

This patch (as1082) makes a small optimization to the way the hub
driver carries out port debouncing immediately after a hub is
activated (i.e., initialized, reset, or resumed). If any port-change
statuses are observed, the code will delay for a minimal debounce
period -- thereby making a good start at debouncing all the ports at
once.
If this wasn't sufficient then khubd will debounce any port that still
requires attention. But in most cases it should suffice; it's rare
for a device to need more than a minimal debounce delay. (In the
cases of hub initialization or reset even that is most likely not
needed, since any devices plugged in at such times have probably been
attached for a while.)

This patch (as1073) adds to khubd a way to recover from power-session
interruption caused by transient connect-change or enable-change
events. After the debouncing period, khubd attempts to do a
USB-Persist-style reset or reset-resume. If it works, the connection
will remain unscathed.
The upshot is that we will be more immune to noise caused by EMI. The
grace period is on the order of 100 ms, so this won't permit recovery
from the "accidentally knocked the USB cable out of its socket" type
of event, but it's a start.
As an added bonus, if a device was suspended when the system goes to
sleep then we no longer need to check for power-session interruptions
when the system wakes up. Khubd will naturally see the status change
while processing the device's parent hub and will do the right thing.
The remote_wakeup() routine is changed; now it expects the caller to
acquire the device lock rather than acquiring the lock itself.

This patch (as1081) straightens out the logic of the hub_restart()
routine. Each port of the hub is scanned and the driver makes sure
that ports which are supposed to be disabled really _are_ disabled.
Any ports with a significant change in status are flagged in
hub->change_bits, so that khubd can focus on them without the need to
scan all the ports a second time -- which means the hub->activating
flag is no longer needed.
Also, it is now recognized explicitly that the only reason for
resuming a port which was not suspended is to carry out a reset-resume
operation, which happens only in a non-CONFIG_USB_SUSPEND setting.

This patch (as1080) makes a significant change to the way khubd
handles port connect-change and enable-change events. Both types of
event are now debounced, and the debouncing is carried out _before_ an
existing usb_device is unregistered, instead of afterward.
This means that drivers will have to deal with longer runs of errors
when a device is unplugged, but they are supposed to be prepared for
that in any case.
The advantage is that when an enable-change occurs (caused for example
by electromagnetic interference), the debouncing period will provide
time for the cause of the problem to die away. A simple port reset
(added in a forthcoming patch) will then allow us to recover from the
fault.

This patch (as1070) creates a new subroutine to check whether a device
can be resumed. This code is needed even when CONFIG_USB_SUSPEND
isn't set, because devices do suspend themselves when the root hub
(and hence the entire bus) is suspended, and power sessions can get
lost during a system sleep even without individual port suspends.
The patch also fixes a loose end in USB-Persist reset-resume handling.
When a low- or full-speed device is attached to an EHCI's companion
controller, the port handoff during resume will cause the companion
port's connect-status-change feature to be set. If that flag isn't
cleared, the port-reset code will think it indicates that the device
has been unplugged and the reset-resume will fail.
