Add initial_freq_list to wpa_supplicant configuration. This option
allows wpa_supplicant to scan a smaller list of frequencies when it
starts. This in turn allows for a faster connection to an already known
network. This limit applies only for the initial scan operation and does
not restrict other channels from being used in consecutive scans.
Tests have shown this to reduce the amount of time for connecting to a
network from roughly 3 seconds to roughly 0.1 second.

The hostapd DFS code deinitializes and initializes the AP interface, if
a clean channel switch is not possible. In this case the AP code paths
would deinit the driver, for example nl80211, without wpa_supplicant
code paths getting notice of this.
Therefore add callbacks for wpa_supplicant mesh methods, which are
called on init/deinit of the AP BSS. These callbacks are then used to
handle the reset in the mesh code.

Mesh interface would have used its channel parameters that were

ssid->frequency is one of the variables used to get the channel number
from a given frequency. Leaving it as unchanged when pri/sec channel
switch will cause picking up a wrong channel number after applying the

Mesh join function is the last function to be called during mesh join
process, but it's been called a bit earlier than it's supposed to be, so
that some mesh parameter values such as VHT capabilities were not
applied correct when mesh join is in process. Moreover, the current
design of mesh join that is called directly after mesh initialization
isn't suitable for DFS channels to use, since mesh join process should
be paused until DFS CAC is done and resumed after it's done.
The callback will be called by hostapd_setup_interface_complete_sync().
There is a possibility that completing mesh init fails, so add error
handling codes for that.

If the maximum operating channel width for AP/P2P GO is not specified,
it is auto-selected during configuration. While selecting the channel
width, if VHT is supported and 160 MHz channels are available, 160 MHz
channel width is preferred to 80 MHz.
During the selection of the channel width, the corresponding driver
capabilities were not checked. As a result, the AP/P2P GO configuration
was set to use the available 160 MHz channels even if the driver did not
have capability to support the 160 MHz channel width causing failure to
start the AP/P2P GO.
Fix this by checking the driver support for the 160 MHz channel width
while selecting the channel width for AP/P2P GO.

The newer kernel versions enforce strict netlink attribute policy
validation and will cause cfg80211 to reject vendor commands with
NL80211_ATTR_VENDOR_DATA if NLA_F_NESTED attribute is not set but
if the vendor command is expecting nested data within
NL80211_ATTR_VENDOR_DATA attribute.
Most of the earlier instances were addressed by adding NLA_F_NESTED
flag in nla_nest_start(). This commit addresses the remaining
instance in which NL80211_ATTR_VENDOR_DATA is populated using data
set by user through the control interface.
Enhance the control interface VENDOR command to indicate whether the
vendor subcommand uses nested attributes within NL80211_ATTR_VENDOR_DATA
attribute or not.
Set NLA_F_NESTED flag for existing QCA vendor commands which use nested
attributes within the NL80211_ATTR_VENDOR_DATA attributes so that the
old frameworks implementations for already existing commands work
without any issues.

Some places in the code base were not using the wrappers like
hostapd_set_oper_centr_freq_seg0_idx and friends. This could lead to
errors, for example when joining 80 MHz mesh networks. Fix this, by
enforcing usage of these wrappers.
wpa_supplicant_conf_ap_ht() now checks for HE capability before dealing
with VHT in order for these wrappers to work, as they first check HE
support in the config.
While doing these changes, I've noticed that the extra channel setup
code for mesh networks in wpa_supplicant/mesh.c should not be necessary
anymore and dropped it. wpa_supplicant_conf_ap_ht() should handle this
setup already.
