 #  Access PXE-compatible devices for network access and network booting.

 #  This driver provides PXE Base Code Protocol which is used to accessing

+#  PXE-compatible device for network access or booting. This driver supports 
+#  both IPv4 and IPv6 network stack.
 #
+#  Notes: 
+#  1) This driver can't co-work with the UefiPxeBcDxe driver in MdeModulePkg. 
+#  2) This driver includes more bugs fix and supports more features (e.g. IPv6, 
+#     MTFTP windowsize) than the UefiPxeBcDxe driver in MdeModulePkg. So, we 
+#     recommand to use this driver even both of them can be used.
