Force to use 32-bit bus
Allocate 4k-aligned buffers
NIC address to DMA data from (def=00000000)
byte swap
Continousely dma data
delay poll dma done polling (def=00000000)
filename
Use high priority DMA Write
Length of DATA in bytes to DMA (def=00000100)
iteration
Buffer offset (def=00000000)
Pattern of Data. 0 - byte increment ; 1- byte decrement
2 - FF's ; 3 - 00's ; 4- AA 55 ... ; 5 - 55 AA ...
