Currently, RDS calls ib_dma_alloc_coherent() to allocate a large piece
of contiguous DMA coherent memory to store struct rds_header for
sending/receiving packets. The memory allocated is then partitioned
into struct rds_header. This is not necessary and can be costly at
times when memory is fragmented. Instead, RDS should use the DMA
memory pool interface to handle this.
