The current API allows the driver to accelerate memset by using the DMA controller. However, it does so over a contiguous memory area, which might proves inefficient when you have to do it over a non-contiguous yet repititive pattern, since you have to create a number of descriptors and then submit each other. Add a memset operation going over a scatter list to handle such cases in a single call.
