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.
