93f8c8e025 wl12xx: set mac80211 flags for A-MPDU aggregation support
We set the mac80211 flag for A-MPDU support and also indicate that
Tx-agg session setup is performed in HW.

This patch depends on
"mac80211: add flag to indicate HW only Tx-agg setup support"

f1acea9a9d wl12xx: AP mode - clean BA and queue state in tx_reset
Reset the BA state of all connected stations and explicitly clear the

f4d3b6ab5e wl12xx: AP mode - enable the BA constraint event from the FW
Unblock the RX BA constraint event from firmware in AP mode as well.
This allows us to stop RX BA sessions when the FW requests it.

In addition refactor the handler for this event to make the flow
clearer.

da03209eac wl12xx: don't regulate links when a single STA is connected
When operating as AP track the number of connected stations. When a
single STA is connected don't regulate the PS status of the link.
Since this is the only STA connected, there's no point holding space in
FW for other links. This will speed up communications with a single
connected STA in PSM.

f8e0af6b87 wl12xx: don't indicate up PS-filtered dummy packets
Dummy packets are currently only sent on the system_hlid link. The
system_hlid link should never be filtered for PS (as it is not
a STA link). Even so, for correctness, don't indicate dummy packets up.
The skb does not belong to mac80211 and as such does not contain a
correct skb->cb.

20a33e52ed wl12xx: ignore sched scan match sets without SSID
For now, cfg80211 only support match sets with SSIDs, but in the
future more parameters will be added.  This patch ignores eventual
matches that do not contain SSIDs in preparation for the future.  This
change also affects the case where broadcast SSIDs are used.  Matching
a broadcast SSID will match everything, so they can be ignored.

fb55377b2a wl12xx: add support for sched_scan filters
Implement support for filtering in scheduled scans.

With this commit we now use the match sets passed by cfg80211 to
filter on SSIDs.  Due to the nature of the wl12xx firmware API, we
don't allow SSIDs to be sent in the probe requests if they are not
going to match any of the filters.

14623787ab wl12xx: don't queue a new dummy packet if one is already pending
The firmware only asks for one dummy packet at a time, but sometimes we
are unable to provide it before a FW timer expires. When this happens,
the FW will re-request the dummy packet. If a packet is still queued in
the driver queues, do nothing in this case.

This prevents spurious dummy packets from clogging up the VO AC.
