This makes the bridge parameter unnecessary for cases where the interface
is already in a bridge and sysfs is mounted to /sys so that the detection
code works.
For nl80211, the bridge parameter can be used to request the AP
interface to be added to the bridge automatically (brctl may refuse to
do this before hostapd has been started to change the interface mode).
If needed, the bridge interface is also created.
Most of this file was already moved into wpa_supplicant/scan.c and
we can remove the file completely by having couple of small helper
functions copied to the remaining users outside core wpa_supplicant
code.
This allows the driver interface to be deinitialized before
struct hostapd_data instance gets freed. This needs to be done so
that the driver wrapper does not maintain a context pointer to
freed memory.
Doxygen and some build tools may get a bit confused about same file
name being used in different directories. Clean this up a bit by
renaming some of the duplicated file names in src/ap.
This code can be shared by both hostapd and wpa_supplicant and this
is an initial step in getting the generic code moved to be under the
src directories. Couple of generic files still remain under the
hostapd directory due to direct dependencies to files there. Once the
dependencies have been removed, they will also be moved to the src/ap
directory to allow wpa_supplicant to be built without requiring anything
from the hostapd directory.
config.c includes now only the generic helper functions that are needed
both for hostapd and the AP mode operations in wpa_supplicant.
hostapd/config_file.c is only needed for hostapd.
set_ap_wps_ie() is not used to set WPS IE for both Beacon and Probe
Response frames with a single call. In addition, struct wpabuf is used
instead of separate u8* and length fields. This avoids duplicated
allocation of the IEs and simplifies code in general.
It would be bettet to avoid including driver_i.h, i.e., direct driver
operation calls from hostapd components. This is an initial step in
that direction for WPS IE updates.
This mode allows associated stations to use 4-address frames to allow
layer 2 bridging to be used. At least for the time being, this is only
supported with driver=nl80211.
