Maciej Sosnowski 16a37acaaf I/OAT: tcp_dma_copybreak default value dependent on I/OAT version 
I/OAT DMA performance tuning showed different optimal values of
tcp_dma_copybreak for different I/OAT versions (4096 for 1.2 and 2048
for 2.0).  This patch lets ioatdma driver set tcp_dma_copybreak value
according to these results.
