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.
