  Log:
  - Convert hme(4) to use TX side bus_dmamap_load_mbuf_sg(9).
  - Move hardware counter reading/zeroing to hme_tick(). This saves
     8 register access per interrupt. [1]
  - Use imax macro for getting max. argument between two integers.
  - Invoke bus_dmamap_sync(9) first before freeing mbuf.
  - Check driver queue first to reduce locking operation in hme_start_locked()
    and interrupt handler.
  - Simplyfy watchdog timer setup in interrupt handler.
  - Don't log normal errors such as RX overrun. If we have DMA stuck
    condition, reinitialize the driver and log it.
