 48                  An array of physical data lane indexes. Position determines how
 49                  lanes are connected to the redriver, It is assumed the same order
 50                  is kept on the other side of the redriver.
 51                  Lane number represents the following
 52                  - 0 is RX2 lane
 53                  - 1 is TX2 lane
 54                  - 2 is TX1 lane
 55                  - 3 is RX1 lane
 56                  The position determines the physical port of the redriver, in the
 57                  order A, B, C & D.
