+#  It might provide TCPv4 Protocol or TCPv6 Protocol or both of them that depends on which network\r

 #\r
+#  Notes:\r
+#  1) This driver can't co-work with the Tcp4Dxe driver in MdeModulePkg.\r
+#  2) This driver includes more bug fixes and supports more features (e.g. IPv6, TCP Cancel\r
+#     function) than the Tcp4Dxe driver in MdeModulePkg. So, we recommend using this driver\r
+#     even though both of them can be used.\r
