The new control interface command RADIO_WORK can be used by external
programs to request radio allocation slots from wpa_supplicant if
exclusive radio control is needed, e.g., for offchannel operations. If
such operations are done directly to the driver, wpa_supplicant may not
have enough information to avoid conflicting operations. This new
command can be used to provide enough information and radio scheduling
to avoid issues with such cases.

Linux capabilities cap_net_admin and cap_net_raw can be used to replace
need for running wpa_supplicant as a root process.

The optional -G<group> command line argument can be used to specify the
group that can access the global control interface.

nl80211 has obsoleted WEXT as the preferred kernel interface for
controlling wireless drivers. Update wpa_supplicant driver interface
list order so that nl80211 gets used first if both nl80211 and wext
interfaces are included in the build. In addition, update README to
reflect the fact that WEXT is obsolete.

Simplify licensing terms for hostap.git by selecting the BSD license
alternative for any future distribution. This drops the GPL v2
alternative from distribution terms and from contribution requirements.
The BSD license alternative that has been used in hostap.git (the one
with advertisement clause removed) is compatible with GPL and as such
the software in hostap.git can still be used with GPL projects. In
addition, any new contribution to hostap.git is expected to be licensed
under the BSD terms that allow the changes to be merged into older
hostap repositories that still include the GPL v2 alternative.

This has been obsoleted by the more generic Linux WEXT (driver_wext.c)
support. The hostap and madwifi driver wrappers can now be used only
with hostapd. The old station interface remains available in releases up
to 1.x.

The driver wrappers broadcom, iphone, osx, and ralink have not been
maintained for a while and it does not look like they will be in the
future either. As such, remove them from the development branch. The
previous versions will be included in older releases up to 1.x.

There is no real reason to maintain these in the current development
branch anymore. If someone really needs support for the obsolete
driver interfaces, these can be found in older wpa_supplicant
branches.
driver_atmel.c
- vendor-specific interface for ATMEL AT76C5XXx cards
- for some old out-of-tree driver; not for the upstream atmel*
drivers
driver_ndiswrapper.c
- vendor-specific interface for an out-of-tree driver
- ndiswrapper should work with driver_wext.c, too
driver_ipw.c
- vendor-specific interface for old ipw2100/2200 driver
- the upstream driver works with driver_wext.c (and does not work
with the old interface)
driver_hermes.c
- vendor driver that was not even included in the main wpa_supplicant
releases
These driver wrappers should not be used anymore; WEXT should be used
instead. However, there may still be users stuck on older kernel versions
that may require driver specific wrappers, so the source code still
remains in the repository.
For example, -Dnl80211,wext could be used to automatically select
between nl80211 and wext. The first driver wrapper that is able to
initialize the interface will be used.
Find attached the patch that creates a new driver: roboswitch. This
driver adds support for wired authentication with a Broadcom
RoboSwitch chipset. For example it is now possible to do wired
authentication with a Linksys WRT54G router running OpenWRT.
LIMITATIONS
- At the moment the driver does not support the BCM5365 series (though
adding it requires just some register tweaks).
- The driver is also limited to Linux (this is a far more technical
restriction).
- In order to compile against a 2.4 series you need to edit
include/linux/mii.h and change all references to "u16" in "__u16". I
have submitted a patch upstream that will fix this in a future version
of the 2.4 kernel. [These modifications (and more) are now included in
the kernel source and can be found in versions 2.4.37-rc2 and up.]
USAGE
- Usage is similar to the wired driver. Choose the interfacename of
the vlan that contains your desired authentication port on the router.
This name must be formatted as <interface>.<vlan>, which is the
default on all systems I know.
