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