be0d54ae39 staging: usbip: userspace: move common cflags to configure.ac
There are a standard set of cflags that are used in each makefile so
let's set those in EXTRA_CFLAGS and enforce them for the entire project.

af8bab0639 staging: usbip: userspace: configure.ac: major overhaul
All parameters have been quoted; and autoscan was rerun so new
headers, types, and functions were added. The deprecated macros
AM_CONFIG_HEADER and AM_PROG_LIBTOOL were changed to
AC_CONFIG_HEADERS and LT_INIT, respectively. The AS_HELP_STRING
macro is used to avoid arbitrary spacing for proper help menu
alignment, and AS_CASE to avoid quoting issues. And finally, the
macros were realigned to allow mere mortals the ability to read them.

28276a28d8 staging: usbip: bugfix for isochronous packets and optimization
For isochronous packets the actual_length is the sum of the actual
length of each of the packets, however between the packets might be
padding, so it is not sufficient to just send the first actual_length
bytes of the buffer. To fix this and simultanesouly optimize the
bandwidth the content of the isochronous packets are send without the
padding, the padding is restored on the receiving end.

dbe79bbe9d USB 3.0 Hub Changes
Update the USB core to deal with USB 3.0 hubs.  These hubs have a slightly
different hub descriptor than USB 2.0 hubs, with a fixed (rather than
variable length) size.  Change the USB core's hub descriptor to have a
union for the last fields that differ.  Change the host controller drivers
that access those last fields (DeviceRemovable and PortPowerCtrlMask) to
use the union.

Translate the new version of the hub port status field into the old
version that khubd understands.  (Note: we need to fix it to translate the
roothub's port status once we stop converting it to USB 2.0 hub status
internally.)

Add new code to handle link state change status.  Send out new control
messages that are needed for USB 3.0 hubs, like Set Hub Depth.

This patch is a modified version of the original patch submitted by John
Youn.  It's updated to reflect the removal of the "bitmap" #define, and
change the hub descriptor accesses of a couple new host controller
drivers.

da13051cc7 USB: Remove bitmap #define from hcd.h
Using a #define to redefine a common variable name is a bad thing,
especially when the #define is in a header.  include/linux/usb/hcd.h
redefined bitmap to DeviceRemovable to avoid typing a long field in the
hub descriptor.  This has unintended side effects for files like
drivers/usb/core/devio.c that include that file, since another header
included after hcd.h has different variables named bitmap.

Remove the bitmap #define and replace instances of it in the host
controller code.  Cleanup the spaces around function calls and square
brackets while we're at it.

01446ef5af staging: usbip: vhci: use urb->dev->portnum to find port
The access to pending_port was racy when two devices
were being attached at the same time.

bd65f6233f staging: usbip: vhci: handle EAGAIN from SO_RCVTIMEO
If there is a receive timeout without any active
requests, we can tell the connection was idle and
ignore the timeout.

If there are active requests for which we expect
to receive a reply we close the connection.

This makes it possible to set an upper bound on
the time a usbip device may be unresponsive.

This is a workaround for the lack of heart-beat
messages in the USBIP protocol.

Extending the protocol would break compatibility
with all previous stub versions, so this seems like
the lesser evil.
