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.

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.

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.

With sequence number and buffer allocation deferred to when they're needed
for the first time, it becomes much easier to start dropping packets from

introduced a check to ensure that packets with non-MCS rates set in
the rate series will not be aggregated. However, it failed to check
if the rate series is valid before testing the flags, thus breaking
aggregation for normal MCS-only packets if the last series is unset.
