When trying to TX through a monitor interface, the
conditions in iwl_mvm_tx_skb_non_sta() don't match
and the frame tries to go out from an usued TXQ.
Add a check for monitor iface, and use the AUX queue
in such a case.
In non-DQA mode the frame is sent through the
static-allocated queues anyway, so the problem is

In case we need to move the scheduler write pointer by
steps of 0x40, 0x80 or 0xc0, the scheduler gets stuck.
This leads to hardware error interrupts with status:
0x5A5A5A5A or alike.
In order to work around this, detect in the transport
layer that we are going to hit this case and tell iwlmvm
to increment the sequence number of the packets. This
allows to keep the requirement that the WiFi sequence
number is in sync with the index in the scheduler Tx queue
and it also allows to avoid the problematic sequence.
This means that from time to time, we will start a queue
from ssn + 1, but that shouldn't be a problem since we
don't switch to new queues for AMPDU now that we have
DQA which allows to keep the same queue while toggling
the AMPDU state.

In BSS mode in the disconnection flow, mac80211 removes
the AP station before the vif is set to unassociated.
Our firmware wants it the other way around: first set
the vif as unassociated, and then remove the AP station.
In order to bridge between those two different behaviors,
iwlmvm doesn't remove the station from the firmware when
mac80211 removes it, but only after the vif is set to
unassociated. The implementation is in
iwl_mvm_bss_info_changed_station:
if (assoc state was modified && mvmvif->ap_sta_id is VALID
&& assoc state is now UNASSC)
remove_the_station_from_the_firmware()
During the recovery flow, mac80211 re-adds the AP station
and then reconfigures the vif. Since the vif is not
associated, and then, we enter the if above (which was
intended to be taken in the disconnection flow only) and
remove the station we just added. This defeats the
recovery flow.
Fix this by not removing the AP station in this flow if
we are in recovery flow.

When sending a Tx Command with a Tx packet, we allocate the
Tx command separately from the payload of the packet.
The WiFi MAC header is then copied into the buffer that was
allocated for the Tx Command. This means that this buffer
needs to be big enough to contain both. This is why it is
allocated with iwl_trans_alloc_tx_cmd which returns a
pointer to a newly allocated not zeroed struct
iwl_device_cmd.
The Tx command has a few bit fields and hence it needs to
be zeroed, but all the rest of the buffer doesn't need to
be zeroed since it will either be memcopy'ed with the MAC
header, or not even sent to the device.
This means that we don't need to zero all the
iwl_device_cmd structure, but rather only the size of
the iwl_tx_cmd structure.
Since sizeof(iwl_tx_cmd) - sizeof(iwl_tx_cmd) is about
260 bytes, this can avoid touching 4 cache lines for each
packet.

In case an assert happens on init flow, the current
driver powers down the NIC, except if iwlmvm modparam
init_dbg=1, and only on very specific flows.
Extend this capability to cover most failure cases
by keeping track of what init configurations have been
completed. This way, we can allow NOT powering down
the NIC, while making sure that when the driver is
removed we don't try to free resources that haven't
been allocated. (This can result in a kernel panic.)

When we want to stop the recording of the firmware debug
and restart it later without reloading the firmware we
don't need to resend the configuration that comes with
host commands.
Sending those commands confused the hardware and led to
an NMI 0x66.
Change the flow as following:
* read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL)
* clear those registers
* wait for the hardware to complete its write to the buffer
* get the data
* restore the value of those registers (to restart the
recording)
For early start (where the configuration is already
compiled in the firmware), we don't need to set those
registers after the firmware has been loaded, but only
when we want to restart the recording without having
restarted the firmware.

Up until now, the driver was comparing the rate reported by the FW and
the rate of the latest LQ command to avoid processing data belonging
to the old LQ command. Recently, FW changed the meaning of the initial
rate field in tx response and it holds the actual rate (which is not
necessarily the initial rate of LQ's rate table). Use instead LQ cmd
color to be able to filter out tx responses/BA notifications which
where sent during earlier LQ commands' time frame.
This fixes some throughput degradation in noisy environments.

This patch implements the idea to have multiple scheduled scan requests
running concurrently. It mainly illustrates how to deal with the incoming
request from user-space in terms of backward compatibility. In order to
use multiple scheduled scans user-space needs to provide a flag attribute
NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is
treated as a legacy scan.
Drivers currently supporting scheduled scan are now indicating they support
a single scheduled scan request. This obsoletes WIPHY_FLAG_SUPPORTS_SCHED_SCAN.

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.
