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.
