Currently we allocate 3 sets of DMA memories from separate pools for each slot. This is inefficient in terms of memory usage (buffers are less than 1 page in size, so we lose due to alignment), and also time spent in doing 3 allocations + de-allocations per slot, instead of 1. To optimise, combine the 3 DMA buffers into a single buffer from a single pool.
