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.
