hostapd_handle_dfs_offload() is the DFS handler for the offloaded case,
in which ieee80211_is_dfs() is used to check if the configured frequency
requires DFS or not.
When the configured channel width is not 20 (e.g., 160),
ieee80211_is_dfs() will not checked adjacent freqs, so it possibly makes
wrong conclusion for whether DFS is required.
hostapd_is_dfs_required() does similar thing with ieee80211_is_dfs()
except it supports checking whether the configured frequency and its
adjacent frequencies require DFS. So hostapd_is_dfs_required() is a more
robust and better option than ieee80211_is_dfs() to check DFS.
The issue is hostapd_is_dfs_required() is for non-offload case due to
the check of the configuration parameter ieee80211h. Add a check for
WPA_DRIVER_FLAGS_DFS_OFFLOAD to make it support the DFS offload case
(i.e., ieee80211h=0) as well.
For example, configuring the AP to start at freq=5240 with channel width
160:
- Existing hostapd checks freq=5240 is non-DFS, hence skip DFS CAC and
transition to AP-Enabled which volatiles DFS-RADAR detection.
LOG: "hostapd : hostapd_handle_dfs_offload: freq 5240 MHz does not
require DFS. Continue channel/AP setup"
- This commit checks freq=5240 and its adjacent freqs are DFS required,
hence remains in DFS state until DFS CAC completed.
LOG: "hostapd : hostapd_handle_dfs_offload: freq 5240 MHz requires
DFS for 4 chans"

When a STA makes an association request that is rejected by an OCE AP
due to the RSSI being insufficient, the AP is added to the driver
disallow list by wpa_set_driver_tmp_disallow_list().
Once the AP increases TX power which makes the AP RSSI higher than
Association Rejection RSSI threshold, the AP is supposed to be removed
from the driver disallow list but that was not the case.
wpa_is_bss_tmp_disallowed() is called in the scan result handler, so it
is the best place to put the logic of removing the AP from the driver
disallow list with sufficient AP RSSI.
This is needed with drivers that use the temporarily disallowed BSS list
(which is currently supported only with a QCA vendor command). The
wpa_supplicant internal functionality was already taking care of this
with the wpa_is_bss_tmp_disallowed() return value even for cases where
the entry remaining in the list.

When regulatory rules are configured not to support 40 MHz channels on
the 2.4 GHz band, hostapd_is_usable_chans() still allowed 40 MHz
channels (i.e., 1-9) to be used with ht_capab=[HT40+][HT40-].
Looking into hostapd_is_usable_chans():
1) Validate primary channel using hostapd_is_usable_chan()
2) Try to pick a default secondary channel if hostapd_is_usable_chan()
3) Try to pick a valid secondary channel if both HT40+/HT40- set, and
further validate primary channel's allowed bandwidth mask.
4) Return channel not usable.
For example, for the 2.4 GHz channel 9 in Japan, its default secondary
channel is 13, which is valid per hostapd_is_usable_chan(), so step (2)
returns channel usable.
Add a more strict check to step (2) to clearly reject 40 MHz channel
configuration if regulatory rules do not allow the 40 MHz bandwidth,
which is similarly done in commit ce6d9ce15b ("hostapd: Add supported
channel bandwidth checking infrastructure").

APs in 6 GHz operating with LPI/VLP rules will have significantly lower
SNR values compared to 2.4/5 GHz band APs. Earlier, the estimated
throughputs were used for comparison only when the delta of SNRs between
both the APs was not greater than 7 and as a result for comparing 6 GHz
APs with 2.4/5 GHz APs, estimated throughputs were not getting used.
The estimated throughput calculations takes SNR value also into
consideration, hence remove RSSI delta check if any of the APs are from
the 6 GHz band. This change is limited to the 6 GHz band only in order
to avoid possible regressions with 2.4/5 GHz APs.
