859cbc396f nl80211: Remove links when stopping AP MLD in hostapd
There is an issue when starting a non-MLD AP on the same interface that
previous operated as an AP MLD. When the previous AP MLD got stopped,
links were not removed when using hostapd. Next non-MLD AP will fail to
start because some nl80211 operations still require link id (e.g., set
freq).

Remove links when AP MLD is stop to avoid such issue. This was already
done in the deinit_ap() handler when using wpa_supplicant, but hostapd
needs to do same.

b3aafd5a87 common: Simplify and avoid confusing defragmentation API
Three functions were provided for defragmentation. First
ieee802_11_defrag(), ieee802_11_defrag_mle() and then
ieee802_11_defrag_data() which would do the actual job. With
ieee802_11_defrag() picking the member in the elements struct for an
EID. The problem with this is, that for the Multi-Link element, there
are multiple entries in the elems struct depending on its type. As such,
remove the intermediate function and simply pass the correct members
directly.

645ec9b58a nl80211: Do a roundtrip to reset event supressions
With nl80211 we need to supress the kernel generated event for any
disconnect and deauthenticate. This code is a bit fragile, as it
assumes that an event will happen. Commit b898b65582 ("nl80211: Do
not ignore disconnect event in case of !drv->associated") changed this
to only disconnect when the driver knows it is associated (apparently
required for P2P), however, deauthentication may also occur without
being associated yet.

Looking at the issue, what we are really interested in is whether the
event belongs to a disconnect/deauth command that we have send
ourselves. Any event happening after the disconnect/deauth completes
should not be suppressed (or after the next connect/auth as that would
be sufficient). We therefore need to know from the event stream
whether events were generated before or after disconnect/deauth
command completion.

To do so, send a simple command on the nl_event socket. As this will
be returned back to us in the correct order with regard to the events.
We can therefore use it to safely reset our internal
ignore_next_local_{deauth,disconnect} variables.

Fix references to the appropriate driver capability drv_flags2. The

790beb84ac Adjust the SNR when comparing BSSes based on Tx power config
The max transmit power of Standard Power (SP) Access Points (AP) on
6 GHz band and APs on 2.4 GHz and 5 GHz bands is limited by effective
isotropic radiated power (EIRP), while the max transmit power of Low
Power Indoor (LPI) APs on 6 GHz Band is limited by power spectral
density (PSD). Therefore the max transmit power of LPI APs grows as the
channel width increases, similar to the noise power which has constant
PSD.

Adjust the SNR of BSSes based on the transmit power config and max
channel width. EIRP limited APs usually have constant max transmit power
on different channel widths, their SNR decreases on larger channel width
because the noise power is higher, while PSD limited APs have constant
SNR over all channel widths.
