Maciej Sosnowski 5de22343b2 I/OAT: set tcp_dma_copybreak to 256k for I/OAT ver.3 ...

Upcoming server platforms from Intel based on the Nehalem performance
have significantly improved CPU based copy performance.
However, the DMA engine can still be effective at higher I/O sizes
for TCP traffic and at this time copybreak
should be set to 256k for TCP traffic only.
