  SVN rev 197465 on 2009-09-24 17:53:00Z by yongari
  
  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.
