NL80211_TESTMODE. svtool is a software validation tool that runs in
the user space and interacts with the device in the kernel space
through the generic netlink message via NL80211_TESTMODE channel.

-config IWL_P2P
- bool "iwlwifi experimental P2P support"
- depends on IWLAGN
- 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.
