This cleans up the driver wrapper interface by getting rid of sta_info.h
dependency in all drivers that use MLME implementation in hostapd
(driver_hostap.c and driver_nl80211.c).
driver.h contains the definitions needed in driver wrapper
implementations (driver_*.c) and driver_i.h contains the definitions
that are used in core hostapd code to interact with the driver wrappers.
This depends on a patch to Linux nl80211/mac80211 that has not yet been
merged into wireless-testing. If that change is not present, the old
mechanism (WEXT) will be used instead.
It is better to pass both HT Capabilities and HT Operation IEs in the
same function call since it may be easier for the driver wrappers to
handle the changes without having to wait for the other IE in the
wrapper code.
This adds WPS support for both hostapd and wpa_supplicant. Both programs
can be configured to act as WPS Enrollee and Registrar. Both PBC and PIN
methods are supported.
Currently, hostapd has more complete configuration option for WPS
parameters and wpa_supplicant configuration style will likely change in
the future. External Registrars are not yet supported in hostapd or
wpa_supplicant. While wpa_supplicant has initial support for acting as
an Registrar to configure an AP, this is still using number of hardcoded
parameters which will need to be made configurable for proper operation.
(e.g., via driver_nl80211 when using mac80211) instead of using hostapd as
the source of the regulatory information (i.e., information from CRDA is
now used with mac80211); this allows 5 GHz channels to be used with hostapd
(if allowed in the current regulatory domain).
The configuration data should only store the static configuration data and
not dynamic data. In addition, storing HT configuration and state in IEs is
not the easiest way of doing this, so use more convenient data types for
storing configuration and dynamic state. The HT IEs are then generated
based on the static configuration and dynamic state whenever needed.
This commit brings in cleaned up version of IEEE 802.11n implementation
from Intel (1). The Intel tarball includes number of other changes, too,
and only the changes specific to IEEE 802.11n are brought in here. In
addition, this does not include all the changes (e.g., some of the
configuration parameters are still missing and driver wrapper changes for
mac80211 were not included).

Sam Leffler <sam@errno.com>:
Attached are changes from Chris Zimmerman (cc'd) to allow drivers to handle
radius ACL's. The patch is against 0.5.10 but I suspect will also apply to
your latest code. These mods enable radius acl support in freebsd w/ my
vap code.
You may want to do the changes to ieee802_11_auth.c differently as they
currently require all participating drivers to work the same. You might be
able to check the return value from hostapd_set_radius_acl_auth and use
that to decide whether the alternate code should be run so you can have 1
driver using this stuff while the other does not.
(jm: Added without more dynamic check for now; in addition, none of the
current in-tree driver wrappers actually implement these handlers, so this
is in preparation for future changes)
