TDLS VHT support requires some more information elements during setup.
While these are not there, mask out the peer's VHT capabilities so that
VHT rates are not mistakenly used.

When TDLS QoS is supported by the the peer and the local card, add
the WMM parameter IE to the setup-confirm frame. Take the QoS settings
from the current AP, or if unsupported, use the default values from
the specification. This behavior is mandated by IEEE802.11-2012 section
10.22.4.

The patch "8f02e6b mac80211: make sure TDLS peer STA exists during

the error.
Fix it by only testing for STA existence during a non-error flow.

Infer the TDLS initiator and track it in mac80211 via a STA flag. This
avoids breaking old userspace that doesn't pass it via nl80211 APIs.
The only case where userspace will need to pass the initiator is when the
STA is removed due to unreachability before a teardown packet is sent.
Support for unreachability was only recently added to wpa_supplicant, so
it won't be a problem in practice.

When a VLAN interface (on top of batX) is removed and
re-added within a short timeframe TT does not have enough
time to properly cleanup. This creates an internal TT state
mismatch as the newly created softif_vlan will be
initialized from scratch with a TT client count of zero
(even if TT entries for this VLAN still exist). The
resulting TT messages are bogus due to the counter / tt
client listing mismatch, thus creating inconsistencies on
every node in the network
To fix this issue destroy_vlan() has to not free the VLAN
object immediately but it has to be kept alive until all the
TT entries for this VLAN have been removed. destroy_vlan()
still removes the sysfs folder so that the user has the
feeling that everything went fine.
If the same VLAN is re-added before the old object is free'd,
then the latter is resurrected and re-used.
Implement such behaviour by increasing the reference counter
of a softif_vlan object every time a new local TT entry for
such VLAN is created and remove the object from the list
only when all the TT entries have been destroyed.

Add new AUX ROC command that is intended for HS2.0 purposes.
It is used to send ANQP requests on a specific channel.
This command requests the firmware to trigger a time event
and remain on a certain channel for a given duration.
Triggering the time event is done by using the Aux
Framework in the firmware, and makes use of the Aux station
(similarly to scan).

Add iwl_mvm_ref_sync() calls (with new ref types) to

These calls make sure the device is out of d0i3,
and the bus is available for direct access.
Since some of these functions are reentrant, convert
the refs_bitmap to a ref counter, so multiple refs
of the same type could be taken concurrently.
