+Intel VMXNET3 driver
+===================
+
+This directory contains source code of FreeBSD VMXNET3 driver released by VMware.
+In which, upt1_defs.h and vmxnet3_defs.h is introduced without any change.
+The other 4 files: includeCheck.h, vmware_pack_begin.h, vmware_pack_end.h and vmxnet3_osdep.h
+are crated to adapt to the needs from above 2 files.
+
+Updating the driver
+===================
+
+NOTE: The source code in this directory should not be modified apart from
+the following file(s):
+
