When a mesh point reconnects by starting from Authentication frame
sequence, the plink count was not decremented from its last connection.
This resulted in leaking peer link count and causing wpa_supplicant to
reject the connection after max_peer_links (default: 99) reconnects.
This was reproduced by pre-configuring 2 mesh points with mesh
credentials. Boot both mesh points and make sure they connect to each
other. Then in a loop reboot one of the mesh points after it
successfully connects while leaving the other mesh point up and running.
After 99 iterations the supplicant on mesh point that is not rebooting
will reject the connection request from the other mesh point.
Fix this by decrementing num_plinks when freeing a STA entry that is
still in PLINK_ESTAB state.

If the local driver indicated a peer candidate event when the peer had
already initiated peering exchange in open mesh case, we used to force a
new exchange to be started instead of allowing the previously started
exchange to complete. This is not desirable, so make this initiation of
the new exchange conditional on there not being an already started (or
successfully completed) exchange.

If the local driver event for a new peer candidate arrived only after
the peer had already initiated the peering exchange, we used to clear
the link state. This resulted in the already completed (or in progress)
exchange getting abandoned and a new exchange initiated. This is not
desirable since the already started (or even completed) exchange can be
used. Clear the link state only when adding the new STA entry for the
first time, i.e., use the same !sta->my_lid condition in handling the
driver event similarly to how the peer initiated cases were already
handled.

From IEEE Std 802.11-2012 13.3.5:
If the incoming Mesh Peering Management frame is for AMPE and the
Chosen PMK from the received frame contains a PMKID that does not
identify a valid mesh PMKSA, the frame shall be silently discarded.
We were not checking the PMKID previously, and we also weren't parsing
it correctly, so fix both.

Mesh Points themselves have capability to support VHT as long as
hardware supports it. However, supporting VHT in mesh mode was disabled
because no one had clearly tested and confirmed its functionality. Since
VHT80 has now been verified to work with ath10k QCA988X driver and
mac80211_hwsim, enable VHT support in mesh mode.

IEEE Std 802.11-2012 13.3.1 states that the AID should be generated on
the local node for each peer. Previously, we were using the peer link ID
(generated by the peer) which may not be unique among all peers. Correct
this by reusing the AP AID generation code.

Currently, there is a race in open mesh networks where mesh STA A
receives a beacon from B and sends a peering open frame to initiate
peering. STA B, having not yet received a beacon from A and thus
created the corresponding station entry, will ignore all such open
frames. If the beacon interval is sufficiently long then peering
will not succeed as a result.
In fact B can simply create the station entry when the popen is
received, as is done in Linux's in-kernel MPM, avoiding the issue.
Signed-off-by: Bob Copeland <me@bobcopeland.com>
Previously, we would only free the station entry if a peering close
frame was received (freeing the station entry causes the kernel to
start sending peer candidate events again when suitable beacons are
received, triggering peering or authentication to restart).
The end result is the same in any case regardless of close reason:
if we leave holding state then peering has started again, so go
ahead and remove the station in all cases.

There is a possible race condition between receiving the
NEW_PEER_CANDIDATE event and the Authentication frame from the peer.
Previously, if the Authentication frame RX event was indicated first,
that frame got dropped silently. Now, this frame is still dropped, but a
copy of it is stored and the frame gets processed on the following
NEW_PEER_CANDIDATE event if that is received for the same peer within
two seconds.
