db63757dbc hostapd: Supply default parameters for OBSS scan
For some client OBSS implementations that are performed in
firmware, all OBSS parameters need to be set to valid values.
Do this, as well as supplying the "20/40 Coex Mgmt Support"
flag in the extended capabilities IE.

67e1a402df hostapd: For VHT 20/40, allow center segment 0 to be zero
The 802.11ac amendment specifies that that the center segment 0 field
is reserved, so it should be zero. Hostapd previously required it to
be set, which is likely a good idea for interoperability, but allow it
to be unset. However, don't allow it to be set to a random value, only
allow zero and the correct channel.

0f23a5e7d6 Mark AP disabled if initialization steps fail
Previously, some of the last initialization steps could fail without
clearly marking the interface disabled. For example, configuring the
channel to the driver could fail, but hostapd would not clearly identify
as the interface not being in functional state apart from not moving it
to the ENABLED state. Send an AP-DISABLED event and mark interface state
DISABLED if such a setup operation fails.

1d91f504e4 hostapd: Process management frames only once per BSS
At least in nl80211, broadcast management frames like Probe Request
frames, may be processed multiple times per BSS if multi-BSS is active
and NL80211_CMD_FRAME event is used to deliver them. In the case of
Probe Request frames, hostapd will create multiple redundant Probe
Response frames which are problematic when many BSS are on one channel.

This problem is caused by driver_nl80211 generating an event for
wpa_supplicant_event() for each BSS, and hostapd_mgmt_rx() calls
ieee802_11_mgmt() for each BSS, too.

Fix this by processing broadcast events only for the BSS the driver
intended to. The behavior is not changed for drivers not setting a BSS.

89de64c5c0 ACS: Fix VHT80 segment picking
For example, the previous implementation considered [44, 48, 52, 56] to
be a valid VHT80 channel -- which it is not. This resulted in, e.g.,
failure to start CAC when channels on overlapped segments included DFS
channels.

Add a check similar to the HT40 one to prevent that. The check is

to be the first channel in a given segment.

354c903f8e AP/GO interface teardown optimization
This commit adds an option to optimize AP teardown by leaving the
deletion of keys (including group keys) and stations to the driver.

This optimization option should be used if the driver supports stations
and keys removal when stopping an AP.

For example, the optimization option will always be used for cfg80211
drivers since cfg80211 shall always remove stations and keys when
stopping an AP (in order to support cases where the AP is disabled
without the knowledge of wpa_supplicant/hostapd).
