  Log:
  MFC 1.42, 1.43: Let the EHCI hardware track the toggle state for
  bulk and interrupt transfers. This fixes some cases where the
  software toggle tracking was not doing the right thing. For example,
  a short transfer that transferred 0 bytes of the requested qTD
  transfer size does cause a toggle change, but the existing code was
  assuming it didn't.
