  SVN rev 196370 on 2009-08-18 21:07:39Z by stas
  
  - Do not try to reevaluate current RX production index on each
    loop iteration as it can be updated by the card while we
    process the RX ring forcing us to process RX descriptors
    for which DMA synchronisation operation has not been
    performed.  This fixes the bug when bge(4) drops packets
    under high load.
