+ * This setup is using SCH-24801 cards with VSC8234 quad SGMII PHY.
+ * LS1028A QDS boards with lane B rework require two cards for the 4 switch
+ * ports, QDS boards without the lane B rework only require one card.
+ *
+ * Switch ports are routed as follows:
+ * Port 0 goes to 1st port of VSC8234 quad card in slot 1,
+ * Port 1:
+ *   - if the QDS has had lane B rework, it is 1st port in slot 2,
+ *   - otherwise it is 2nd port in slot 1.
+ * Port 2:
+ *   - if DIP SW5[1] = 0 it is 3rd port in slot 1,
+ *   - otherwise it is 1st port in slot 3.
+ * Port 3:
+ *   - if DIP SW5[2-3] = 00b it is 4th port in slot 1,
+ *   - if DIP SW5[2-3] = 01b it is 2nd port in slot 3,
+ *   - if DIP SW5[2-3] = 11b it is 1st port in slot 4.
+ *
+ * The following DTS assumes QDS lane B rework and DIP SW5[1-3] = 000b.  Two
+ * SCH-24801 cards are required in slots 1 and 2.
