Support change to ADD_STA API to support station types.
Each station is assigned its type.
This simplifies FW handling of the broadcast and multicast
stations:
* broadcast station is identified by its type and not the mac
address.
* multicast queue is no longer treated differently. The opening
and closing of it is done by referring to its station.
There is no need to specify it in the MAC command.
* When disabling TX to all station driver can disable the traffic
on multicast station, so FW doesn't have to do it.
Change is backward compatible.
Change the order of adding and removing the stations according to
FW requirements.

cab_queue can now get bigger than u8, since in TVQM we will support
512 queues..
Support it by maintaining internal mapping between the actual number
and mac80211 queue (IWL_MVM_DQA_GCAST_QUEUE).
For pre-a000 the internal queue will be the same as the mac80211
queue.

In a000 devices we will support up to 32 stations.
The max station define is used also for invalid station marking
which makes finding usages of actual maximum station pretty hard
to sort through - change it to be a different define in order
to make future changes easier.
Use also ARRAY_SIZE intead of define when possible.
Do not move yet to 32 stations until firmware do it though.

Currently multicast queue is associated with the broadcast
station.
This raises quite a few issues:
The multicast queue has a special treatment:
- It is sent in the MAC context command
- It is excluded from tfd_queue_mask
In DQA mode we end up enabling two queues - the probe response
queue and the multicast queue - with the same station (broadcast)
and TID while in DQA mode it should be unique RA-TID.
Firmware will enforce it for a000 devices, so this allocation
will fail.
In addition, in a000 devices the FW will set the FIFO and not
the driver. So there is a need for FW to know when we enable
the queue that it is multicast queue so it will be bound to
the multicast FIFO. There is no such way in current design.
In order to simplify driver and firmware handling of this queue
create a multicast station.
This solves the unique RA-TID issue in the short term and serves
as preparation for the long term.
In the long term we will also add a flag marking this station for
the FW as the multicast station.
Once we will do that the FW will know this is the multicast queue
immediately when it is added and bind it to the correct FIFO.
It will also enable removing the special treatment of the
queue in the MAC context command.

A few of the static queues are enabled along with the bcast
STA. Make sure they are removed along with it, rather than
waiting for the mac ctxt release.
This is needed because we sometimes have a STA being removed
and then added again (either with the same sta_id or a
different one). If we wait for the mac ctxt release we will
try to allocate the queues again (as this is currently done
in the STA allocation and not in the MAC init) although
they weren't freed, and even if the sta_id of the STA has
changed.

Currently when configuring the cab queue the scheduler is configured
without station id - which results in station id 0.
In DQA mode this causes firmware to assert later on when the actual
station 0 is added with an empty tfd_queue_mask.
Fix that by configuring the queue to the broadcast station.
This is a bit trickier since the queue should not be included in the
tfd_queue_mask of the ADD_STA since it is a multicast queue, and the
tfd_queue_mask is only unicast queue. As a result the queue should be
enabled only after the broadcast station is added.

There's no need for the common MAC context function to have an

Add support CSA countdown offloading. When CSA starts, the driver
specifies the offsets to the eCSA and CSA IEs in the beacon template
command and the fw performs the countdown.
The fw notifies the driver when the channel switch flow
should be performed.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

"DQA" is shorthand for "dynamic queue allocation". This
enables on-demand allocation of queues per RA/TID rather than
statically allocating per vif, thus allowing a potential
benefit of various factors.
Please refer to the DOC section this patch adds to sta.h to
see a more in-depth explanation of this feature.
There are many things to take into consideration when working
in DQA mode, and this patch is only one in a series. Note that
default operation mode is non-DQA mode, unless the FW
indicates that it supports DQA mode.
This patch enables support of DQA for a station connected to
an AP, and works in a non-aggregated mode.
When a frame for an unused RA/TID arrives at the driver, it
isn't TXed immediately, but deferred first until a suitable
queue is first allocated for it, and then TXed by a worker
that both allocates the queues and TXes deferred traffic.
When a STA is removed, its queues goes back into the queue
pools for reuse as needed.

When forming IBSS, mac80211 scans in order to find an already
existing cell to join.
In case the scan does not find any existing cell a new IBSS
cell is formed.
When receiving the beacons of another IBSS cell we should
merge if the other IBSS cell's TSF is higher than ours.
However, currently iwlmvm does not set any timestamp flag in
rx_status so there is no valid rx timestamp to compare the
beacon's TSF to.
The reason for that is that TSF as indicated by the firmware
is at INA time, but up till now mac80211 expected the TSF at
the beginning or end of the MPDU.
Set the flag to the newly added RX_FLAG_MACTIME_PLCP_START flag.

When in AP mode we need to filter in beacons from other APs to update HT
operation mode. As a power optimization the beacons are filtered out when
there are no associated stations. As a result, when there are no
associated stations, we will not update the HT operation mode until a
station connects.
Add a debugfs parameter that allows to disable this optimization.

Currently firmware is configured to filter out beacons. In case
a beacon was changed - it is waking the host.
However, some vendors change their IEs frequently without any
significant change, and redundant wakeups are triggered as a
result.
As a solution disable beacon filtering when entering d0i3.
Instead, firmware will store the latest beacon and upon exiting
d0i3 it will send it up to the host, so the host can act upon
changes (if there were any).
This beacon will arrive as a dedicated notification - support it
as well.

The commit below called iwl_mvm_mac_ctxt_changed() to handle
a case that the vif is a P2P GO.
However iwl_mvm_mac_ctxt_cmd_go() ignores the number of
associated stations and asks the FW to pass beacons anyways.
Fix this by checking ap_assoc_sta_count parameter, in iwl_mvm_mac_ctxt_cmd_go()
as well, and ask the FW to pass beacons only when there's
at least one associated station.

Currently when creating a new vif in monitor mode the driver doesn't
allocate a specific station. This causes that in the situation that
tx traffic is injected, the tx queues are not scheduled,
with the result of a TFD queue hang.
Fix that by allocating a station and ensuring its tx queues
are scheduled.
