- 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.
