[Qemu-devel] [PATCH 00/18] ehci updates

[Gerd Hoffmann]

  Hi,

Here comes a patch series with a bunch of updates for the ehci host
controller.  Two important changes:  First ehci supports queuing now,
i.e. more than a single packet per endpoint can be in flight at the same
time, which improves usb-host performance.  Second the wakeup rate is
adaptive now, so ehci will have alot less wakeups when the usb bus is
idle.  Also a bunch of minor fixes and cleanups.

Post-freeze material.

please review,
  Gerd
