- MFC r198318:
  - On entrance to the rx_eof sync RX rings maps with POSTWRITE flag
    instead of POSTREAD: the hardware do not touch this memory (CPU
    updates it).  It is already synchronized as PREWRITE after the
    processing is done.

  - Synchronize RX return ring memory in rx_eof.  This is needed
    as the deviced updates this memory when receives packets.

  - Decouple the synchronization of BGE status block in the interrupt
    service routine: perfrom PREREAD synchronization only all accesses
    to this block are finished.  This seems to be more natural.
