  - Use our own callout instead of if_slowtimo() for driving lance_watchdog()
    in order to avoid races accessing if_timer.
  - Use bus_get_dma_tag() to obtain the parent DMA tag so le(4) works on
    platforms requiring this.
  - Remove BUS_DMA_WAITOK from bus_dma_tag_create() invocations as it's
    no valid flag there.
  - For setting the port PCnet chips must be powered down or stopped and
    unlike documented may not take effect without an initialization. So
    don't invoke (*sc_mediachange) directly in lance_mediachange() but
    go through lance_init_locked(). It's suboptimal to impose this for
    all chips but given that besides the affected PCI bus front-end the
    only other front-end which supports media selection is and likely
    ever will be the 'ledma' front-end I see not enough reason to break
    the in-driver API for this (though one could argue both ways here).
