iwlwifi: mvm: Refactor and fix max probe len computation
Move iwl_mvm_max_scan_ie_len function to scan.c and fix the
implementation to conform with the LMAC scan API.
Since the correct implementation would leave us with unacceptably
tiny probes, add a workaround which returns a larger value.
In current implementation it's possible that unified_scan_lmac and
unified_sched_scan_lmac would return -ENOBUFS.

iwlwifi: mvm: rs: fix logic in case of multiple TIDs
In case of traffic on multiple TIDs where one is aggregated
and the other is not RS would toggle between considering
traffic vs. the station as aggregated and not aggregated.
Instead consider the sta state as aggregated as long as
there's at least one TID aggregated.
This limitation is because the rates table is kept per

iwlwifi: mvm: report all BA notifs to RS
Currently BA notifications which don't reclaim any frames
would not cause the RS to be called as no skbs are passed
to mac80211. This is not optimal as RS can benefit from the
statistics of sent vs. acked of such a BA. This can improve the
reaction time of the RS algorithm. Also, an upcoming change in
the firmware would cause BA timeout to be reported as a BA notif
with 0 acked so this change is required for that as well.

The scheduler is a HW sub-block that directs the work of the Flow
Handler by issuing requests for frame transfers, specifying source

TX FIFOs based upon a pre-determined mapping.
The driver has some responsibilities to the scheduler, namely
initialising and maintaining the hardware registers. This is
currently done by directly accessing them, which can cause races
with the firmware also accessing the registers.
To address this problem, change the driver to no longer directly
access the registers but go through the firmware for this if the

However, for some chips which dont support 11AC mode current config_bands

iwlwifi: mvm: rs: don't zero tx stats after idle
Move the tx stats to the persistent area of lq_sta to
avoid them being zeroed out every time rs reinitializes
which happens after tx idle for 5 secs for example.
The automatic zeroing out made them difficult to use.

We rely on the value of the mvm->ucode_loaded flag to decide whether

entries), so we need to reset it when the mac80211 stop operation is
called and the hardware is shutdown.

iwlwifi: mvm: rs: remove max_rate_idx
max_rate_idx constraint is deprecated and it's handling is
faulty as well as it is relevant only for legacy rates but
was considered in HT/VHT. In most cases there was no side effect
as max_rate_idx was set to -1 but in certain cases like P2P
it got set to an actual rate idx which would limit the maximum
rate in HT/VHT by mistake.
max_rate_idx should be replaced by the masks fields but for
now remove it.

Bluetooth: Fix re-setting RPA as expired when deferring update
The hci_update_random_address will clear the RPA_EXPIRED flag and
proceed with setting a new one if the flag was set. However, the
set_random_addr() function that is called may choose to defer the update
to a later moment. In such a case the flag would incorrectly remain
unset unless set_random_addr() re-sets it. This patch fixes the issue.
