/**
\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.
