I'm trying to write a driver for a card which doesnt support scatter gather
(i.e. dma requires one "contiguous" segment).
I was wondering if there's anyway to use mbuf data memory for dma.
(considering that mbuf memory could be distributed in multiple physical
segments). _bus_dma_load_mbuf() probably woudnt work because it returns you
an array of segments..?
