5ef8e39fa7 nl80211: Fix interface-in-different-bridge case
The local ifindex list needs to be updated only if the current bridge
interface is the correct one. If hostapd is going to move the interface
to another bridge, the old bridge ifindex must not be added. In
addition, when removing the bridge interface on deinit, it may need to
be set down to allow bridge removal.

533fe09b78 nl80211: Fix no-encrypt for IEEE 802.1X WEP EAPOL
Commit 9f12614b8c ('nl80211: Do not
encrypt IEEE 802.1X WEP EAPOL') tried to use
NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT to disable encryption of EAPOL
frames for WEP IEEE 802.1X. However, it used incorrect key management
suite (IEEE 802.1X with WPA/WPA2 while the non-WPA version is needed
here). Consequently, the no-encrypt flag was never set to the driver
(WPA/WPA2 cases do not meet the WEP as pairwise criteria).

5b78493f3b mesh: Add mesh interface creation command for mesh gate
The mesh gate is used to bridge (or route) between mesh network and
another network. For example, mesh gate acts as router between mesh
network and IEEE 802.11 BSS network.

This command makes a virtual mesh interface to be used for mesh gate.

This command expects to be used like this.

wpa_cli -i wlan0 MESH_INTERFACE_ADD ifname=mesh0
wpa_cli -i mesh0 add_network
wpa_cli -i mesh0 set_network 0 ssid '"commell_2X_mmm"'

4bd7195466 nl80211: Try to unmask 11b rates again on next connection request
It is possible for unmasking of 11b rates to fail if a P2P group is
terminated while the netdev is down (e.g., due to rfkill block). This
could result in the 11b TX rates being left masked for non-P2P
operations. This would be particularly unfortunate for channel 14 use
since OFDM rates are not allowed on channel 14 and only OFDM rates were
configured P2P. This issue showed up, e.g., when running hwsim test case
rfkill_autogo followed by ap_wps_conf_chan14.

It may be possible to allow the failed operation in cfg80211/mac80211,
but it looks better to work around this on wpa_supplicant side as well.
Try to unmask the 11b rates again on the next connection request if the
rate unmasking operation had failed.

0d4e3d1d13 nl80211: Ignore Connect failure for the previous association
Suppose there are two APs (AP1 & AP2) and user attempted to connect to
AP2 before the previous connection with AP1 could succeed. Now, if the
connection event comes for the older AP with failed status, we should
just ignore it as the wpa_supplicant state has moved to "ASSOCIATING"
with the new AP (AP2).

This is a similar to the case where a disconnection event is ignored for
a case where local disconnect request can cause the extra event to show
up during the next association process following that command.

It was possible for the ignore_if_down_event flag to remain set in some

temporarily. If that happened, the following rfkill interface down could

this up by clearing the ignore_if_down_event flag on the interface down
event regardless of whether the interface is up at the time this event
