 #  TCPv4 I/O and TCPv6 I/O services.

 #  This module provides EFI TCPv4 Protocol and EFI TCPv6 Protocol to send and receive data stream.
-#  It might provide TCPv4 Protocol or TCPv6 Protocol or both of them that depends on

+#  It might provide TCPv4 Protocol or TCPv6 Protocol or both of them that depends on which network
+#  stack has been loaded in system. This driver supports both IPv4 and IPv6 network stack.
 #
+#  Notes:
+#  1) This driver can't co-work with the Tcp4Dxe driver in MdeModulePkg.
+#  2) This driver includes more bug fixes and supports more features (e.g. IPv6, TCP Cancel
+#     function) than the Tcp4Dxe driver in MdeModulePkg. So, we recommend using this driver
+#     even though both of them can be used.
