54                  An array of physical data lane indexes. Position determines how
55                  lanes are connected to the redriver, It is assumed the same order
56                  is kept on the other side of the redriver.
57                  Lane number represents the following
58                  - 0 is RX2 lane
59                  - 1 is TX2 lane
60                  - 2 is TX1 lane
61                  - 3 is RX1 lane
62                  The position determines the physical port of the redriver, in the
63                  order A, B, C & D.
