  SVN rev 198922 on 2009-11-04 19:01:35Z by yongari
  
  MFC r197461:
    Use __NO_STRICT_ALIGNMENT to determine whether de(4) have to apply
    alignment fixup code for received frames on strict alignment
    architectures.
  
  MFC r197463:
   Consistently use bus_addr_t.
  
  MFC r197464:
    Destroy dmamap in dma cleanup.
  
  MFC r197465:
    Align Tx/Rx descriptors on 32 bytes boundary instead of PAGE_SIZE.
    Also align setup descriptor on 32 bytes boundary. Tx buffer have no
    alignment limitation so create dmamap without alignment
    restriction[1]. Rx buffer still seems to require 4 bytes alignment
    limitation but we can simply use MCLBYTES for size to map the
    buffer instead of TULIP_DATA_PER_DESC as the buffer is allocated
    with m_getcl(9).
    de(4) supports up to TULIP_MAX_TXSEG segments for Tx buffers,
    increase maximum dma segment size to TULIP_MAX_TXSEG * MCLBYTES.
    While I'm here remove TULIP_DATA_PER_DESC as it is not used anymore.
  
    This should fix de(4) breakage introduced after r176206.
