+/**
+\page driver_wrapper Driver wrapper implementation (driver.h, drivers.c)
+
+All hardware and driver dependent functionality is in separate C files
+that implement defined wrapper functions. Other parts
+of the hostapd are designed to be hardware, driver, and operating
+system independent.
+
+Driver wrappers need to implement whatever calls are used in the
+target operating system/driver for controlling wireless LAN
+devices. As an example, in case of Linux, these are mostly some glue
+code and ioctl() calls and netlink message parsing for Linux Wireless
+Extensions (WE). Since features required for WPA were added only recently to
+Linux Wireless Extensions (in version 18), some driver specific code is used
+in number of driver interface implementations. These driver dependent parts
+can be replaced with generic code in driver_wext.c once the target driver
+includes full support for WE-18. After that, all Linux drivers, at
+least in theory, could use the same driver wrapper code.
