+	  This option enables experimental P2P support for some devices
+	  based on microcode support. Since P2P support is still under
+	  development, this option may even enable it for some devices
+	  now that turn out to not support it in the future due to
+	  microcode restrictions.
+
+	  To determine if your microcode supports the experimental P2P
+	  offered by this option, check if the driver advertises AP
+	  support when it is loaded.
+
+	  Say Y only if you want to experiment with P2P.
