There is no reason to have a separate usb_generic_handle_packet function
any more, fold it into usb_handle_packet(). Also call the do_token_*
functions which handle control transfer emulation for control pipe
packets only.

All drivers except usb-hub use usb_generic_handle_packet. The only
reason the usb hub has its own function is that it used to be called
with packets which are intended for downstream devices. With the new,
separate device lookup step this doesn't happen any more, so the need
for a different handle_packet callback is gone.
So we can kill the handle_packet callback and just call
usb_generic_handle_packet directly. The special hub handling in
usb_handle_packet() can go away for the same reason.

Implement the find_device callback for the usb hub. It'll loop over all
ports, calling usb_find_device for all enabled ports until it finds a
matching device.
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
Add usb_find_device(). This function will check whenever a device with
a specific address is connected to the specified port. Usually this
will just check state and address of the device hooked up to the port,
but in case of a hub it will ask the hub to check all hub ports for a
matching device.
This patch doesn't put the code into use yet, see the following patches
for details.
The master plan is to separate device lookup and packet processing.
Right now the usb code simply walks all devices, calls
usb_handle_packet() on each until one accepts the packet (by returning
something different that USB_RET_NODEV). I want to have a device lookup
first, then call usb_handle_packet() once, for the device which actually
processes the packet.

The USB subsystem pipes internal reset notifications through
usb_handle_packet() with a special magic PID. This indirection
is a pretty pointless excercise as it ends up being handled by
usb_generic_handle_packet anyway.
Replace the USB_MSG_RESET with a usb_device_reset() function
which can be called directly. Also rename the existing usb_reset()
function to usb_port_reset() to avoid confusion.

According to the EHCI spec port ownership should revert to the EHCI controller
on device disconnect. This fixes the problem of a port getting stuck on USB 1
when using redirection and plugging in a USB 2 device after a USB 1 device
has been redirected.

The OS is allowed to make the UHCI Controller run in circles. That is
usually done to serve multiple connected USB devices in a robin-round
fashion, so the available USB bandwidth is evenly distributed between
devices.
The uhci emulation handles this in a very poor way though. When it
figures it runs in circles it stops processing unconditionally, so
it usually processes at most a single transfer desriptor per queue,
even if there are multiple transfer descriptors are queued up.
This patch makes uhci act in a more sophisticated way. It keeps track
of successful processed transfer descriptors and transfered bytes. Then
it will stop processing when there is nothing to do (no transfer
descriptor was completed the last round) or when the transfered data
reaches the usb bandwidth limit.
Result is that the usb-storage devices connected to uhci are ten times
faster, mkfs.vfat time for a 64M stick goes down from five seconds to
a half second. Reason for this is that we are now processing up to 20
transfer descriptors (with 64 bytes each) per frame instead of a single
one.

In some cases, a legacy property does need a special print method
but not a special parse method. In this case, we can reuse the get/set
from the static (non-legacy) property.
If neither parse nor print is needed, though, do not register the
legacy property at all. The previous patch ensures that the right
fallback will be used.

There's no need to call into ->parse and ->print manually. The

Limit them to the device_add functionality. Device aliases were a hack based
on the fact that virtio was modeled the wrong way. The mechanism for aliasing
is very limited in that only one alias can exist for any device.
We have to support it for the purposes of compatibility but we only need to
support it in device_add so restrict it to that piece of code.
