    sys/dev/netif/bge    if_bge.c 
  Log:
  For bge_rxeof(), return immediately if no RX descs need to be processed, this
  optimization avoids two unnecessary register accessing and increase performance
  a lot.  Same optimization is applied to bge_txeof(), but it will not have
  real effect until bge(4) uses busdma(4) (i.e. will avoid extra sync)
