There are bandwidth 320 MHz-1 and 320 MHz-2 channelization in EHT mode.
When using ACS, user might prefer one of the channelization or both, but
original ACS was unable to take such preference.
Another problem is that the original ACS returns only the ideal channel
but no 320 MHz channelization. The function acs_get_bw_center_chan()
also could not correctly return the center frequency of bandwidth 320
MHz that is decided by ACS.
For example, if ACS decide the ideal channel is channel 37 with
channelization 320 MHz-2 (center frequency 6265 MHz),
acs_get_bw_center_chan() returns 6105 MHz, which is 320 MHz-1.
Extend the support for 320 MHz so that ACS can choose the best channel
according to the user's preference. Also, after calling
acs_find_ideal_chan_mode(), the best channel and bandwidth can be
derived.
The changes are:
- bw_type ACS_BW320 is divided into ACS_BW320_1 and ACS_BW320_2
- in bandwidth 320 MHz, find the best channel and bandwidth according to
user's perference (320 MHz-1, 320 Mhz-2 or both are OK)
- before acs_find_ideal_chan_mode() returns, update bw320_offset in
iface->conf so that the best channel's channelization is recorded.
- get the best center frequency from bw320_offset

Introduce a new configuration option, "eht_bw320_offset", which enables
devices to specify a preferred channelization for 320 MHz BSSs when
using automatic channel selection (ACS). This option is applicable only
when the channel is not already decided and the bandwidth is set to 320
MHz.
The value and meaning of the option:
0: auto-detected by ACS
1: 320 MHz-1
2: 320 MHz-2

Fix the following bugs about selecting the best channels in the segment:
1. If the 'update_best' once became false, it never becomes true again.
In other word, if one of the channels in the segment is not usable,
the remaining channels in the segment were never able to be the best
channel.
2. The primary channel in the segment might not be usable due to the
insufficient survey data. Therefore, it cannot be the best channel and
we cannot take its factor/weight into account.

Currently while deciding to create a new Multiple BSSID element based on
the condition when the length reaches 255, the length value being used
is the total element length (including the length of the Element ID and
Length fields as well). However, the value in the length field denotes
the number of octets following it and excluding itself. Hence including
the total length is wrong. This leads to incorrect count of Multiple
BSSID elements.
And while filling the data, the length is considered porperly as it
should be hence we are filling more data in a single go and all data is
filled in MBSSID count which is less than originally calculated. This
ultimately leads to incorrect length calculation during nla_put() and
setting the beacon to the driver fails while putting the Multiple BSSID
element data into the netlink socket buffer.
Fix this issue by considering the length excluding the Element ID and
Length field sizes.

This function is both updating the hostapd-internal sta->flags value and
sending out the AP-STA-CONNECTED control interface message. When
authorizing a STA, the call to this function is followed by a driver
command to update the flags of the STA entry in the driver. That has a
race condition at least for UML time-travel since the AP-STA-CONNECTED
event is used as a message to wait for before running a connectivity
test or some other operation that depends on the data connection being
in working condition.
Split the function into two steps so that the driver STA entry update
can be done between those two steps for the cases where it matters for
the race condition. In other words, send the AP-STA-CONNECTED message
only after having authorized the STA in the driver.
