Allow switching back to legacy Tx columns so we'll stop doing HT/VHT in case we're far from the AP. Stop active aggregation when making a deciding to stay in a legacy column. Despite having low legacy rates in the LQ table lower entries it doesn't help much in case we're doing aggregations as the aggregation was being transmitted in the initial rate of the table. This should help traffic stalls when far from the AP.

After being idle for a long time (>5sec) the rs statistics will be stale so we prefer to reset rs and start from legacy rates again. This gives better results when the attenuation increased signficantly (e.g. we got further from the AP) and after a while we start Tx Note that the first Tx after the idle period will still go out in the old modulation and rate but this seemed a simpler approach compared to adding a timer or modifying mac80211 for this. The negative impact is negligble as we'll recover quickly.

Change the down/upscale decision logic a bit to be based on different success ratio thresholds. This fixes the implementation compared to the rate scale algorithm which was planned to yield optimal results. Also fix a case where a lower rate wasn't explored despite being a potential for better throughput. While at it rewrite rs_get_rate_action to be more clear and clean.

If we have no beacon data before association, delay smart FIFO enablement until after we have this data. Not doing so can cause association failures in extremely silent environments (usually only a shielded box/room) as beacon RX is not sent to the host immediately, and then the association time event ends without the host receiving any beacon even though it was on the air - it's just stuck on the FIFO.

The watchdog thread waits on completion that is set from a timer. As the completion is count based this could mean that on a busy system the watchdog is handled multiple times with a very short interval. This is not the intended behaviour. After handling the watchdog it should wait for the next timer expiry. This is accomplished by reinitializing the completion.

It is possible that pairing fails after we've already received remote identity information. One example of such a situation is when re-encryption using the LTK fails. In this case the hci_conn object has already been updated with the identity address but user space does not yet know about it (since we didn't notify it of the new IRK yet). To ensure user space doesn't get a Pair Device command response with an unknown address always use the same address in the response as was used for the original command.

When performing SMP pairing with MITM protection one side needs to enter the passkey while the other side displays to the user what needs to be entered. Nowhere in the SMP specification does it say that the displaying side needs to any kind of confirmation of the passkey, even though a code comment in smp.c implies this. This patch removes the misleading comment and converts the code to use the passkey notification mgmt event instead of the passkey confirmation mgmt event.

On 2.4Ghz band, the channels overlap since the delta between different channels is 5Mhz while the width of the receiver is 20Mhz (at least). This means that we can hear beacons or probe responses from adjacent channels. These frames will have a significant lower RSSI which will feed all kinds of logic with inaccurate data. An obvious example is the roaming algorithm that will think our AP is getting weak and will try to move to another AP. In order to avoid this, update the signal only if the frame has been heard on the same channel as the one advertised by the AP in its DS / HT IEs. We refrain from updating the values only if the AP is already in the BSS list so that we will still have a valid (but inaccurate) value if the AP was heard on an adjacent channel only. To achieve this, stop taking the channel from DS / HT IEs in mac80211. The DS / HT IEs is taken into account to discard the frame if it was received on a disabled channel. This can happen due to the same phenomenon: the frame is sent on channel 12, but heard on channel 11 while channel 12 can be disabled on certain devices. Since this check is done in cfg80211, stop even checking this in mac80211.

Since Stanislaw's patch removing the quiescing code, mac80211 had a race regarding suspend vs. authentication: as cfg80211 doesn't track authentication attempts, it can't abort them. Therefore the attempts may be kept running while suspending, which can lead to all kinds of issues, in at least some cases causing an error in iwlmvm firmware. Fix this by aborting the authentication attempt when suspending.
