With firmwares which do not support rsn capability override

To fix this, do not advertise HT cap with cfg80211 for

This patch enables all multicast packets in non suspend mode
and enable multicast filtering in wow suspend mode. This also
fixes a bug in multicast where the driver assumed disable
multicast-all command disabled/filtered all multicast
packets, which was wrong assumption, because firmware will
apply the programmed filter.

Multicast requirements
 - Enable forward all multicast packets(no filtering) in
      non suspend mode.
 - Enable multicast filtering in wow suspend mode for both
      AP and CLIENT.

Set max_scan_ssids and max_sched_scan_ssids to same value. These use the
same probed SSID list, so there is no point in using different maximum
number of SSIDs.

Clear probed SSID entries that are not used. This was already done for
sched_scan, but not for scan. Be consistent and clear the table for both
cases to avoid leaving bogus entries.

In addition, share the same function for setting the probed SSIDs for
scan and sched_scan paths. This fixes setting of wildcard SSID flag
(ANY_SSID_FLAG) and changes the scan path to use probed SSID index
consistently (i.e., start with 0 similarly to sched_scan; firmware
will handle the needed internal mapping).

This adds a DFS pattern detector to ath9k. It is fed with pulse events
by the radar pulse detector and reports in place whether a pattern
was detected. On detection, the result is reported as radar event to
the DFS management component in the upper layer.

Currently the ETSI DFS domain is supported with detector lines for
the patterns defined by EN-301-893 v1.5.1. Support for FCC and JP
will be added gradually.

To include the pattern detector, ath9k must be built with support
for DFS certified config flag set (CONFIG_ATH9K_DFS_CERTIFIED).

The queue mapping redesign that I'm planning to do
will break pure injection unless we handle monitor
interfaces explicitly. One possible option would
be to have the driver tell mac80211 about monitor
mode queues etc., but that would duplicate the API
since we already need to have queue assignments
handled per virtual interface.

So in order to solve this, have a virtual monitor
interface that is added whenever all active vifs
are monitors. We could also use the state of one
of the monitor interfaces, but managing that would
be complicated, so allocate separate state.

This field is never set to anything non-zero in
mac80211, so we should be able to remove it.
Unfortunately though, the iwlwifi and iwlegacy
drivers use it for their internal TX status
processing (which shouldn't be using the rate
control API to start with), so add a new field
"status.antenna" for them, at least for now.

In the future, I plan to use the new field to
hold the hardware queue, while the SKB's queue
mapping holds the AC.
