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.
