In the MLD case, the information from the transition management request
is relevant during the association process in order to filter out links
that were disallowed by the BTM request. Also, the information remains
useful should a connection attempt fail.
To enable these scenarios, keep the information around until the
connection has completed. As this might make it impossible to establish
a connection, also clear this information at the same time that a normal
BSS ignore is cleared to avoid getting stuck in case the transition
fails unexpectedly.

When accepting a BSS transition request there is a race between
sending the response and roaming to the target AP. As a result,
the response may not be sent because the station deauthenticated
from the AP before the response was actually sent.
To make sure the BSS transition response is sent, start roaming only
after the TX status is received for the BSS transition response.

When channel 140 is configured in mesh, interface fails to come up due
to channel bond (136,140). Since Channel 136 is not HT40+ capable,
validation for HT channel bonding fails when it checks whether first
channel in the bond (channel 136) is HT40+ capable.
In mesh, during channel setup, secondary channel offset for the
configured channel will be selected as +1 if primary channel is capable
of HT40+. In current code, channel 140 is not allowed as HT40+ and hence
secondary channel offset is selected as -1, which makes 136 as secondary
channel. But channel 136 is not HT40+ supported and fails in channel
bonding validation.
Add 140 to HT40+ allowed list as HT40+ is supported for the channel.

Since wpa_supplicant version 2.10 the extended capabilities MSCS and SCS
are advertised in the (Re)Association Request frames.
This causes the association request to be rejected by several access
points. Issue was observed with:
- D-Link DIR600
- TP-Link AC1900
- Synology MR2200ac
To avoid this issue the extended capabilities MSCS and SCS shall only be
added if the bss also supports them. While this may not follow the exact
behavior described in IEEE 802.11, this is a reasonable compromise to
avoid interoperability issues since these capabilities cannot be used
with an AP that does not support them anyway.
Note: The Extended Capabilities element is only included in the
Association Request frames if the AP also sent its extended capabilities
(see wpas_populate_assoc_ies()) as a workaround for misbehaving APs.
This workaround exists since version 2.1.

In theory, each device that supports WMM (or the IEEE 802.11 QoS for
that matter) is expected to advertise how many replay counters it
supports and the peer device is supposed to use that information to
restrict the total number of different MSDU priorities (AC/UP) that
might be used. In practice, this is not really done in deployed devices
and instead, it is just assumed that everyone supports the eight
different replay counters so that there is no need to restrict which
MSDU priorities can be used.
hostapd implementation of WMM has advertised support for 16 PTKSA replay
counters from the beginning while wpa_supplicant has not had any code
for setting the supported replay counter fields in RSNE, i.e., has left
the value to 0 which implies that only a single replay counter is
supported. While this does not really result in any real issues with
deployed devices, this is not really correct behavior based on the
current IEEE 802.11 standard and the WMM specification.
Update wpa_supplicant to use similar design to the hostapd RSNE
generation by setting the number of supported PTKSA replay counters to
16 whenever WMM is enabled. For now, this is done based on the
association being for HT/VHT/HE/EHT and also based on the AP supporting
WMM since it is much more likely for the local device to support WMM and
eight replay counters (which can be indicated only with the value that
implies support for 16 counters since there is no separate value for 8).
