Now that we can use driver_nl80211.c with non-mac80211 drivers that
implement SME/MLME internally, we may not get inactivity time from the
driver. If that is the case, we need to skip disconnection based on
maximum inactivity timeout. This fixes some unexpected disconnection
cases with ath6kl in AP mode.

hostapd uses the poll method to check if the station is alive
after the station has been inactive for ap_max_inactivity seconds.
Make the poll mechanism configurable so that user can choose to
disconnect idle clients.
This can be especially useful when some devices/firmwares have
restrictions on the number of clients that can connect to the AP
and that limit is smaller than the total number of stations trying
to use the AP.

Add a new persistent group network block field, p2p_client_list, to
maintain a list of P2P Clients that have connected to a persistent
group. This allows GO of a persistent group to figure out more easily
whether re-invocation of a persistent group can be used with a specific
peer device.

This allows per-device PSK to be configured for WPA-Personal using a
RADIUS authentication server. This uses RADIUS-based MAC address ACL
(macaddr_acl=2), i.e., Access-Request uses the MAC address of the
station as the User-Name and User-Password. The WPA passphrase is
returned in Tunnel-Password attribute in Access-Accept. This
functionality can be enabled with the new hostapd.conf parameter,
wpa_psk_radius.

Append "p2p_dev_addr" parameter to AP-STA-DISCONNECTED event for P2P
connections. In addition, for AP-STA-CONNECTED event during P2P
connection, the "dev_addr=" print is replaced with "p2p_dev_addr=" to
be more consistent with other events.

Instead of trying to remember to add wpa_msg() calls for every possible
path where a STA becomes authorized or unauthorized, use
ap_sta_set_authorized() to send these events more consistently.

Currently, there is no events over the control interface
when a AP disconnects a station due to inactivity. With
this patch, an "AP-STA-DISCONNECTED" event will be sent.

This offloads the station polling to driver wrappers, which may offload
it again to the driver. The hostap driver wrapper uses "real" data
frames while nl80211 uses null data frames.
Also add a specific event to indicate that a poll was successful for
future use with the nl80211 driver.
When polling a station that has been inactive for a while, hostapd currently
always uses a null data frame. This is a bit strange with uAPSD clients
(though it seems to mostly work) since the EOSP bit can never be set in a
non-QoS frame. Make hostapd use QoS null data frames for probing when the
station is a QoS STA.

The Deauth/Disassoc TX status callbacks were ending up kicking the
station entry from kernel driver when test functionality was used to
inject Deauth/Disassoc frames from the AP with the purpose of leaving
the local association in place. Fix this by using STA flags to figure
out whether there was a pending callback for the frame that we need
to act on.
In addition, add forgotten functionality for the Disassoc TX status
callback to match the behavior with Deauth.
This allows the driver to use PS buffering of Deauthentication and
Disassociation frames when the STA is in power save sleep. The STA
entry (and PTK) will be removed from the kernel only after the
Deauth/Disassoc has been transmitted (e.g., when the STA wakes up).
A hardcoded two second timeout is used to limit the length of this
window should the driver fail to deliver the frame (e.g., the STA
is out of range and does not wake up). The kernel STA entry is
marked unauthorized during the wait to avoid accepting Data
frames from the STA that we have decided to disconnect.
This behavior is available only with drivers that provide TX status
events for Deauth/Disassoc frames (nl80211 at this point). Other
drivers continue to use the previous behavior where the STA entry
is removed immediately.
Add MAC addresses for stations and use wpa_msg instead of printf
methods to make it easier to grep logs and find messages for the
station in question.

This is not needed anymore and just makes things more difficult
to understand, so move the remaining function pointers to direct
function calls and get rid of the struct hostapd_driver_ops.
Commit bf65bc638f started the path to
add this new abstraction for driver operations in AP mode to allow
wpa_supplicant to control AP mode operations. At that point, the
extra abstraction was needed, but it is not needed anymore since
hostapd and wpa_supplicant share the same struct wpa_driver_ops.
Start removing the unneeded abstraction by converting
send_mgmt_frame() to an inline function, hostapd_drv_send_mlme().
This is similar to the design that is used in wpa_supplicant and
that was used in hostapd in the past (hostapd_send_mgmt_frame()
inline function).
For now, this applies to the test command that can be used to set
periodic NoA (p2p_set noa). The value are stored and periodic NoA
is enabled whenever there are no non-P2P STAs connected to the GO.
With this patch, a client gets kicked out of the last BSS it was
attached to, when it is associating to a different one.
While mac80211 does allow a station to be present on multiple bss
interfaces, this does seem to cause problems both for the stack
and for hostapd.
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.
