  SVN rev 204155 on 2010-02-21 00:00:55Z by yongari
  
  Increase PCIe maximuim read request size to 2048. Because re(4) uses
  Tx DMA burst size 2048, I beleive PCIe maximum read request size
  also should match to the value of Tx DMA burst size. With this
  change I can get more than 800Mbps for TCP bulk transfers.
  Previously I was not able to get more than 700Mbps. If I enable TSO
  it now shows 927Mbps.
