+Subject: [PATCH 18/18] Support OOT and In-tree drivers switch
+
+In order to select between the in-tree and OOT drivers, a cmdline
+parameter multi-drivers-switch need be used. If cmdline parameter
+multi-drivers-switch is set to cvl-4.0.1, the OOT drivers will be
+loaded by "insmod" command before udevd is started, and that ensures
+that the OOT drivers will be loaded rather than the in-tree drivers.
+
+The default drivers will be the in-tree drivers if there is not
+multi-drivers-switch in the cmdline parameters or it is not set
+correct, because the out-of-tree drivers have been moved to the
+"weak-updates" subdirectory, we would like them to have a lower
+precedence/lower priority than the in-tree versions.
+
+Note: The in-tree drivers will use the OOT drivers' ice.pkg file,
+The version is 1.3.30.0. We will wait Intel's test result and give
+feedback which DDP package should be used for the in-tree drivers,
+and do the related update.
