AFAIK the DMA engine

Kernel version is 2.6.30 and I have enabled fsl DMA engine during
configuring kernel. After system booted, I have seen only 38 DMA
interrupts, and no increase later when I am doing data transfer
through network.
So I wonder if mpc8548 had made use of DMA engine when doing memcpy,
or maybe if
