+X-QSGMII-16PORT riser card
+----------------------------
+The X-QSGMII-16PORT is a 4xQSGMII/8xSGMII riser card with eighth SerDes
+interfaces implemented in PCIe form factor board.
+It supports followings
+ - Card can operate with up to 4 QSGMII lane simultaneously
+ - Card can operate with up to 8 SGMII lane simultaneously
+
+Supported card configuration
+	- CSEL  : ON ON ON ON
+	- MSEL1 : ON ON ON ON OFF OFF OFF OFF
+	- MSEL2 : OFF OFF OFF OFF ON ON ON ON
+
+To enable this card: modify hwconfig to add "xqsgmii" variable.
+
+Supported PHY addresses during SGMII:
+#define XQSGMII_CARD_PHY1_PORT0_ADDR 0x0
+#define XQSGMII_CARD_PHY1_PORT2_ADDR 0x2
