  SVN rev 213596 on 2010-10-08 18:51:28Z by yongari
  
  MFC r212069,212071:
  r212069:
    bge_txeof() already checks whether it has to free transmitted mbufs
    or not by comparing reported TX consumer index with saved index. So
    remove unnecessary check done after freeing transmitted mbufs.
    While I'm here nuke unnecessary variable initializations.
  
  r212071:
    Remove unnecessary atomic operation in bge_poll. bge(4) always
    holds a driver lock in the function entry and
    memory synchronization is handled by bus_dmamap_sync(9).
