Based on IEEE P802.11be/D5.0, when a station is non-AP MLD with more
than one link the combination of the Link Removal Imminent field set to
1 and the BSS Termination Included field set to 1 means than only one of
the links is removed while the other links will remains associated.
Handle this case without starting a scan to find another BSS.

If ioctl() returns EBUSY on the command SIOCBRADDIF, the interface might
have already been added to the bridge by an external operation (e.g.,

Check whether the interface is correctly brigded when ioctl()
returns EBUSY and if so, report success.

There are different CHAN_SWITCH flows for DFS and non-DFS channels.
Non-DFS one saves previous BW value in iface->conf, but DFS flow
replaces it with a new user requested value. Setting a non-DFS channel
after a DFS one with BW = 160 would have resulted in a mismatch between
the saved BW and vht_capab (if VHT160 was not included by default). This
would have led to a check fail in the hostapd_set_freq_params()
function.

It is possible for the start_listen() callback to be called to request
the driver to start a driver operation and stop_listen() called
immediately after that (e.g., due to a request to transmit a P2P Public
Action frame) before the driver has had time to start ROC and send an
event to notify of that. Such a sequence could result in
p2p->pending_listen_freq being left to a nonzero value without getting a
call to p2p_listen_cb() to clear it. This would stop an ongoing P2P
listen operation since no following p2p_listen() call would start the
listen due to the pending command being assumed to be in effect.
Fix this by detecting this particular sequence and clearing
p2p->pending_listen_freq.
This was found with the p2p_listen_and_offchannel_tx test case with the
new kernel scheduled and UML time-travel.

With changes to optimize scan for specific BSSID, there arises a
scenario where in nl80211_trigger_scan() is called with a scan
randomization enabled. A combination of NL80211_ATTR_MAC for BSSID and
scan randomization, which uses NL80211_ATTR_MAC for a different purpose,
results in invalid error for the scan request. To fix the issue use
attribute NL80211_ATTR_BSSID instead of NL80211_ATTR_MAC.
NL80211_ATTR_BSSID was introduced in kernel commit 2fa436b3a2a7
("nl80211: Use different attrs for BSSID and random MAC addr in scan
req") in 2016. Prior to that, only NL80211_ATTR_MAC could be used for
specifying the target BSSID. For backwards compatibility, add the
NL80211_ATTR_MAC attribute as well when not using a random MAC address.

All the station flags other than WPA_STA_SHORT_PREAMBLE are relevant
only for the MLD station and not to the link stations (as these flags
are related to the MLD state and not the link state).
As for the WPA_STA_SHORT_PREAMBLE, since the station is an EHT
station, it must have short preamble.
Thus, do not propagate the flags change for link stations to the driver.

qca_wlan_vendor_attr_tpc definition to query transmit power information
on STA interface from the driver for a connected AP.
The information includes regulatory max transmit power limit, AP local

For PSD power mode, the information includes PSD power levels for each
subchannel of operating bandwidth. The information is driver calculated
power limits based on current regulatory domain, AP local power
constraint and other IEs. The information will be set to target. Target

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.

address from the Basic ML element, as it is possible that the station

a case the underlying driver would not perform address translations).
