  Log:
  SVN rev 192281 on 2009-05-18 01:51:52Z by delphij
  
  DMA synchronization fixes:
  
   - In bce_rx_intr(), use BUS_DMASYNC_POSTREAD instead of
     BUS_DMASYNC_POSTWRITE, as we want to "read" from the
     rx page chain pages.
   - Document why we need to do PREWRITE after we have updated
     the rx page chain pages.
   - In bce_intr(), use BUS_DMASYNC_POSTREAD and
     BUS_DMASYNC_PREREAD when before and after CPU "reading"
     the status block.
   - Adjust some nearby style mismatches/etc.
