If CONFIG_DRIVER_WEXT=y is not used in .config, but driver_wext.c
gets pull in to help another driver wrapper, rfkill code needs to
included to fix the build.
Add a new wpa_supplicant state: interface disabled. This can be used
to allow wpa_supplicant to be running with the network interface even
when the driver does not actually allow any radio operations (e.g.,
due to rfkill).
Allow driver_nl80211.c and driver_wext.c to start while rfkill is in
blocked state (i.e., when ifconfig up fails) and process rfkill
events to block/unblock WLAN.
The ps3 wireless kernel driver has wireless extension support.
There is a legacy wpa_supplicant driver, and support for this
has been removed from the kernel driver, as no distributions
are using it.
Number of Linux driver wrappers included this more or less identical
function, so lets add a new helper file to be able to share some more
code between the driver wrappers.
As an initial step in sharing netlink helper functions among driver
wrappers, create a new file for netlink code and move operstate send
function there.
The Prism54.org project seems have been dead for a while and it does not
look like this driver would ever be maintained again. Furthermore, it is
difficult to find a version that would work with the driver_prism54.c
wrapper and there is another driver for these card in the Linux kernel
tree.
The hostapd integration in driver_prism54.c is quite different from the
other driver wrappers and would require major effort to get it cleaned
up. Since there does not seem to be any real users for the cleaned up
version, there does not seem to be justification to spend this effort on
the wrapper. This old code is making it much more difficult to clean up
the driver interface and at this point, the best option seems to be to
remove the driver wrappers. Should someone really still need this, the
old code will continue to be available in hostapd 0.6.x.
Instead of having all driver stuff collected across wpa_supplicant
and hostapd, create a common snippet that they both include and
that handles the build configuration.
