ad08e1413b hostapd: Move ctrl_iface initialization to happen earlier
Channel determination may take considerable time when ACS or DFS is
used, so it is useful to be able to observe this process through the
control interface. Move the initialization of the control interfaces to
happen before channel determination so that this can be achieved.

4a5deb9b9d hostapd: Simplify interface initialization
Use hostapd_interface_init2() for all interfaces instead of the
previously used different paths for per-interface-config and
per-BSS-config cases. This moves the calls to hostapd_driver_init() and
hostapd_setup_interface() to happen after all configuration files have
been read.

71cdf6b624 hostapd: Fix ENABLE failure to not remove interface
Previously, ENABLE command ended up freeing the hostapd_iface context on
initialization failures, but did not even remove the interface from the
list of available interfaces. This resulted in use of freed memory with
any following operation on the same interface. In addition, removing the
interface on initialization failure does not seem like the best
approach. Fix both of these issues by leaving the interface instance in
memory, but in disabled state so that the configuration can be fixed and
ENABLE used again to enable the interface or REMOVE used to remove the
interface.

When removing and re-adding the first wlan# netdev to hostapd
dynamically, the netdev is already present and should not be removed and
re-added to maintain its state as not-added-by-hostapd so that it does

813d4bac5a DFS: Add support for multi-BSS
If radar was detected single BSS is notified about it. This caused only
that single BSS to be stopped and restarted. However, due to nl80211
interface combinations the BSS was not started on a new channel and
other BSSes remained operating on the old channel.

The downside is that hostapd_disable_iface() causes deauth frames to be
sent. This is undesired but on the other hand it doesn't make sense to
create workarounds that imitate CSA's 'block tx'. For proper Tx
quiescing CSA should be properly implemented.

ed1bf011da Allow hostapd config file for dynamically added interface
This extends hostapd global control interface command "ADD" to use a
configuration file instead of requiring configuration to be built using
SET command.

The command format is now following:
ADD <ifname> <control path|config=<path to config>>

For example:

ADD wlan0 /var/run/hostapd
ADD wlan0 config=/tmp/hostapd.conf

When using the configuration file option, ctrl_interface parameter in
the file needs to be set to allow ENABLE command to be issued on the new
interface.

3f9a8137f5 hostapd: Add a config option to control beaconing
In a AP/STA concurrent setup, if the STA interface is continually
scanning, trying to connect to a network, the AP interface
is basically broken since beaconing would be erratic.

This option can be used in a WDS setup where one AP acts as a
Client/AP-Repeater. The Repeater AP interface has to start beaconing
only after the Client interface has established a WDS link with the
"Root AP".
