cfg80211: Allow TDLS peer AID to be configured for VHT

Setup and then update information on this STA entry based on what was
received from the peer during the setup exchange.

In theory, this could use NL80211_ATTR_STA_AID to set the peer AID just
like this is used in AP mode to set the AID of an association station.
However, existing cfg80211 validation rules prevent this attribute from
being used with set_station operation. To avoid interoperability issues
between different kernel and user space version combinations, introduce
a new nl80211 attribute for the purpose of setting TDLS peer AID. This
attribute can be used in both the new_station and set_station
operations. It is not supposed to be allowed to change the AID value
during the lifetime of the STA entry, but that validation is left for

mac80211: close AP_VLAN interfaces before unregistering all

Since Eric's commit efe117ab8 ("Speedup ieee80211_remove_interfaces")
there's a bug in mac80211 when it unregisters with AP_VLAN interfaces
up. If the AP_VLAN interface was registered after the AP it belongs
to (which is the typical case) and then we get into this code path,
unregister_netdevice_many() will crash because it isn't prepared to
deal with interfaces being closed in the middle of it. Exactly this
happens though, because we iterate the list, find the AP master this
AP_VLAN belongs to and dev_close() the dependent VLANs. After this,
unregister_netdevice_many() won't pick up the fact that the AP_VLAN
is already down and will do it again, causing a crash.

mac80211: assign AP_VLAN hw queues correctly

A lot of code in mac80211 assumes that the hw queues are
set up correctly for all interfaces (except for monitor)
but this isn't true for AP_VLAN interfaces. Fix this by
copying the AP master configuration when an AP VLAN is
brought up, after this the AP interface can't change its
configuration any more and needs to be brought down to
change it, which also forces AP_VLAN interfaces down, so
just copying in open() is sufficient.
