+       help
+         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.
