Support for the LP-PHY.
The LP-PHY is a low-power PHY built into some notebooks
and embedded devices. It supports 802.11a/g
(802.11a support is optional, and currently disabled).
This is heavily experimental, and probably will not work for you.
Say N unless you want to help debug the driver.

This option enables some additional warnings that help
cfg80211 developers and driver developers, but that can
trigger due to races with userspace.
For example, when a driver reports that it was disconnected
from the AP, but the user disconnects manually at the same
time, the warning might trigger spuriously due to races.
