The supplicant code does not try to control the actual channel of the
radio at any point. It simply passes the target peer and channel
parameters to the driver. It's the driver's responsibility to
periodically initiate TDLS channel-switch operations when TDLS
channel-switching is enabled.
Allow enable/disable operations to be invoked via the control interface.

The specification requires the tspecs to be kept upon reassociation to

If registering WMM-AC ADDTS response action frame or WMM-AC DELTS
action frame fails, the management frame handler is not being
registered. This results with a segmentation fault when trying to
unsubscribe the handler when the interface is removed.
Fix it by always registering the handler and just returning a negative
value to note that the action frame could not be registered.

The way autolink support is implementing in Doxygen is a bit
inconvenient with wpa_supplicant being recognized as something that
would always be linked to struct wpa_supplicant. In addition, number of
links were not really noticed automatically. To get this working more
robustly and without having to use the %wpa_supplicant workaround (which
had its own issues, e.g., with titles), disable autolinking and use
explicit \ref commands instead.
This is also updating some of the obsolete notes to point to correct
file names, etc. changes in the source code tree.

The previous version was enabling all three stations at the same time
and left dev[1] and dev[2] competing on getting connected with dev[0]
that allowed only one pairing. This was not exactly robust and the pass
criteria depended on an extra event from either dev[1] or dev[2]. Fix
that by first connecting dev[0] and dev[1] and only after that, start
dev[2]. This allows proper validation of both the peering limit on
dev[0] and no extra event on dev[2].

Previously, role="enrollee" was required to be used to allow the AP mode
WPS operation to be started. This is incorrect since the AP/GO will
operate in Registrar role. Fix this by ignoring the role parameter when
AP (including P2P GO) mode is enabled.
Signed-off-by: Jouni Malinen <j@w1.fi>
Start of station-mode WPS PBC/PIN/Registrar/NFC operation would result
in the AP mode getting disabled. This can be particularly confusing for
the P2P GO case where the group would need to be stopped cleanly. As
such, it is better to reject these invalid operations rather than trying
to handle all corner cases needed to allow this to work robustly.

There is no need to limit this property based on the role of the device
in the group, so return the passphrase if it is available. It will be
available in GO role and it may be available in P2P Client role based on
whether the peer GO provided it during the WPS provisioning step.

This was returning a byte array of the pointer to the PSK, not the
actual PSK, due to incorrect use of

None of the new D-Bus interface cases use the bssid_part in
decompose_object_path (while the old interface ones do). As such, this
is dead code and can be removed. In addition, the P2P addition here was
pretty ugly extension. Replace these with a cleaner way of passing the
separating string (e.g., "Networks") from the caller and returning the
requested item.
In addition, there is no need to allocate the returned item separately,
so use a single allocation and a pointer to that allocated memory. This
will make it easier for callers to have to free only a single
allocation. This is also fixing a memory leak in P2P invitation
persistent group case where the caller had missed the need to free the
returned values.
