Why is fwserial bigger?
1) Exclude the dma_fifo* files in the comparison, because block & net
devices get dma-able memory management from their subsystems.
2) Certain tty concepts don't map well to an automated bus, so these are
simulated (eg, break handling)
3) fwserial has to implement a protocol to virtually cable peers
4) sbp_target only supports 1 target.
