13daed58c7 Include driver.h in hostapd.h
This allows use of structs (and not only pointers) defined in drivers.h.
Remove also some not needed forward declarations and redundant includes.

afadaff976 Optimize 40 MHz HT co-ex scan on AP
Only scan the affected channels instead of all enabled channels when
determining whether the primary and secondary channel for HT40 needs to
be swapped. This speed up HT40 setup considerably on 5 GHz band.

If ACS fails we still need to call hostapd_setup_interface_complete.
Otherwise hostapd will just hang doing nothing anymore. However, pass
an error to hostapd_setup_interface_complete to allow a graceful fail.

e76da50529 hostapd: Add AP DFS support
Add DFS structures/events handlers, CAC handling, and radar detection.
By default, after radar is detected or the channel became unavailable, a
random channel will be chosen.

This patches are based on the original work by Boris Presman and
Victor Goldenshtein. Most of the DFS code is moved to a new dfs.c/dfs.h
files.

50f4f2a066 hostapd: Add Automatic Channel Selection (ACS) support
This adds ACS support to hostapd. Currently only survey-based
algorithm is available.

To use ACS you need to enable CONFIG_ACS=y in .config and use
channel=0 (or channel=acs_survey) in hostapd.conf.

For more details see wiki page [1] or comments in src/ap/acs.c.

3aea5fbe3b hostapd: Do not change HT40 capability due to OBSS scan
The capability itself isn't really affected by an OBSS
scan, only the HT operation must then be restricted to
20 MHz. Change this, and therefore use the secondary
channel configuration to determine the setting of the
OP_MODE_20MHZ_HT_STA_ASSOCED flag.

This shouldn't really change anything functionally,
it just makes the code a little less confusing and
is also needed to implement more dynamic bandwidth
changes if ever desired.

f0898e9519 Make copies basic_rates list more useful
Commit e5693c4775 added a copy of the
determined basic rate set into struct hostapd_iface, but did not
actually copy the terminating -1 value. This could be problematic if
something were to actually try to use this list since would be no way to
know what is the last entry in the list. Fix this by copying the
terminating value.

1b4d379366 AP: Ensure ieee80211n_supported_ht_capab() gets called to check ht caps
ieee80211n_supported_ht_capab is called after ieee80211n_check_40mhz in
function hostapd_check_ht_capab. ieee80211n_check_40mhz can return 1 in
a valid scenario where the initialization is completed in a callback. In
this case ieee80211n_supported_ht_capab is skipped and hostapd does not
check the ht capabilities reported by the driver. Fix this issue making
sure ieee80211n_supported_ht_capab gets called.
