Decoding an sbus number on UE10000

example: /sbus@41,0/qec@1,20000/qe@3,0


/sbus@41  => system board 0, sysio 1



			4		1
                  ------------      ----------
                  0 1       00      00      01
                    -       ----------       -
                    A           B            C



A => 1 = IO or 0 = PROC

B => system board number 0-F

C => sysio number 0-1


/qec@1 = sbus slot 1

sbus slot number 0-1



system board		sysio0			sysio1
