  SVN rev 199668 on 2009-11-22 20:31:40Z by yongari
  
  For MSI case, interrupt is not shared and we don't need to force
  PCI flush to get correct status block update. Add an optimized
  interrupt handler that is activated for MSI case. Actual interrupt
  handling is done by taskqueue such that the handler does not
  require driver lock for Rx path. The MSI capable bge(4) controllers
  automatically disables further interrupt once it enters interrupt
  state so we don't need PIO access to disable interrupt in interrupt
  handler.
