Crashing on recovery is useful for debugging, as a JTAG

(otherwise, a reconfiguration will occur)

When setting the WL1271_SCAN_OPT_PRIORITY_HIGH flag, the
driver requests a scan *now*, and the fw doesn't enter psm
before scanning, which in turn might cause packets loss.

Subject: 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.

Subject: wl12xx: remove deprecated CONFIG_WL12XX_HT flag

The driver now support HT properly, so we can always have HT enabled.

Remove the WL12XX_HT configuration.

Subject: 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.

Subject: wl12xx: increase number of allowed SSIDs in sched_scan

The latest firmware supports up to 16 SSIDs in the scheduled scan
lists.  Increase the number we report to cfg80211 and increase the
min/max dwell time to 30 and 60 TUs respectively, because otherwise we
don't have the time to send the probes for all SSIDs.

Subject: 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.

Subject: 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.

Subject: 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.

Subject: 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.

Subject: 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"
