Once the FW supports autonomous decision between STBC/BFER/SISO
we no longer set the STBC bit and ANT_AB in the rate table.
However the FW rate in the tx response will have the STBC
or BFER bit set and the antennas set to ANT_AB in case these
were chosen by it. This will cause us to discard any such
response as unmatching the current LQ table and thus break
the rs search cycle completely.
Fix this by relaxing the rate matching in case we're working
with the new API and STBC/BFER are used.

During out-of-channel activities (e.g. scan) TDLS ch-switch responses from

activity is complete, which can be in the order of several seconds.
Since TDLS ch-sw has no dialog-token-like mechanism for distinguishing
sessions, use the GP2 time of the incoming ch-switch response to discern
validity. For this purpose record the GP2 time of an outgoing TDLS ch-sw
request and compare to the Rx time of the ch-sw response.

When we resume from WoWLAN, the firmware may have crashed

meaningless value. When we come to compare
trans_pcie->scd_base_addr (which really holds the value we

Note that when the WoWLAN has crashed, we will see that
in iwl_trans_pcie_d3_resume which will let the op_mode

it asked to stop the scheduled scan and didn't notify the
end of the scheduled scan. Besides a fat warning, this led
to a situation in which cfg80211 would refuse any new scan
request.
To disentangle this, fake that the scheduled scan has been
stopped without sending the command to the firwmare, return
0 after having properly let cfg80211 know that the scan
has been cancelled.
This is basically the same as:

BAR tx cmd tid was set to non qos (8). This is wrong as BAR
should be sent with the tid of the BA session.
This led to a corruption in the firmware. The visible
effect of this from the driver side is the BA notification

In 8000 B-step the FW file has changed, but by the time we
know the HW step, the FW file is already requested.
This patch defaults 8000 family to B-step if no HW step is
detected in time. When it can it checks what HW step it
really is (in 8000 family) and if it isn't B-step, the FW
file is released and the A-step file is requested.

When another vif is also running during a channel switch, we need to
use a session protection when we move to the new channel, so that we
don't miss the beacons. Without this, sometimes the other vif
repeatedly gets time exactly when we should be hearing the beacons,
preventing channel switch from completing. Adding a session
protection that lasts from the moment the channel changes until 2
TBTTs later, ensures that we will hear the beacons on the destination
channel.

After a channel switch, transmission on the new channel is only

We need to call ieee80211_chswitch_done() ourselves just when the
absence TE started, so we perform the actual context switch early

ieee80211_chswitch_done() to complete the operation.

Now that mac80211 waits for the first beacon on the new channel before

Instead of using a hardcoded number of TUs before beacon 0 as the time
to start the absence and actual channel switch, calculate it in
relation to the beacon interval. We use 10 TUs + beacon interval
before beacon 0 to target a bit before beacon 1. This gives us enough
time to switch to the new channel before the AP/GO switches.

Add an absent time event when pre_channel_switch is called and use the

packets while the AP/GO is performing its actual switch.

Now that all CSA flows are using the switch_vif_chanctx op, we can

functions to decide whether the context switch flows need to be
executed. In this way we make the chanctx switch flow more generic,

The spec requires to decrement the CSA counters based on TBTT,
regardless if the beacon was actually transmitted. Previously, the fw
would send beacon notifications only for successfully transmitted
beacons. This behavior resulted in inaccurate CSA countdown. In order
to address this issue, the fw was changed to send beacon
notifications also for not transmitted beacons. Such notifications
have TX_STATUS_INTERNAL_ABORT (0x92).
Don't start the CSA countdown before first successfully transmitted
beacon, in order to guarantee that the CSA is announced for a
required period.

In the original driver, we decided to not implement WEP RX hardware
offload because of a quirk with the firmware API - it allows setting
global WEP keys that then get used for all virtual interfaces, which
is clearly wrong if more than one exists, and it allows setting per-
station keys but then separates multicast and unicast keys.
In order to implement WEP RX hardware offload, work around these
limitations by uploading each WEP key twice, once as multicast and
once as unicast, but point them both to the same key slot (offset)
and use the same key material so the slot overwrite on the second
upload doesn't actually change anything. Upon removal, also remove
the key twice so the station no longer references it.
