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.
