mwifiex: Track BA sequence number reset
Some stations reset the sequence number for traffic-ids (TIDs)

after the ADDBA falls outside the receive window for this TID but

this AP has reset its sequence number during the ADDBA. In this

cfg80211: remove radar requirements check from cfg80211_can_use_iftype_chan()
We don't have to double check whether the parameters passed to
cfg80211_can_use_iftype_chan() are correct. We should just make sure
they *are* when we call this function.
Remove the radar_detect argument check in
cfg80211_can_use_iftype_chan() to simplify the code.

mac80211: allow drivers to request SMPS off

cfg80211: docbook: fix small formatting error
docbook (or one of its friends) gets confused with semi-colons in the
argument descriptions, causing it to think that the semi-colon is
marking a new section in the description of addr_mask in wiphy struct.
Prevent this by using hyphens instead of semi-colons in the mask
example.

cfg80211: regulatory: introduce NL80211_RRF_AUTO_BW rule flag
Introduce NL80211_RRF_AUTO_BW rule flag. If this flag set
maximum available bandwidth should be calculated base on
contiguous rules and wider channels will be allowed to cross
multiple contiguous/overlapping frequency ranges.
In case of old kernels maximum bandwidth from regulatory
rule will be used, while there is no NL80211_RRF_AUTO_BW flag.
This fixes the previous commit 9752482083066af7ac18a5ca376f
("cfg80211: regulatory introduce maximum bandwidth calculation")
which was found to be a problem for userspace API compatibility.

Bluetooth: Increase minor version of core module
With the addition of Resolvable Private Address (RPA) resolution
support for Bluetooth Low Energy connections, it makes sense to
increase the minor version of the Bluetooth core module.
The module version is not used anywhere, but it gives a nice extra
hint for debugging purposes.

Bluetooth: Fix channel check when binding RFCOMM sock
When binding RFCOMM socket with non-zero channel we're checking if
there is already any other socket which has the same channel number
assigned and then fail. This check does not consider situation where
we have another socket connected to remote device on given channel
number in which case we still should be able to bind local socket.
This patch changes __rfcomm_get_sock_by_addr() to return only sockets
in either BT_BOUND or BT_LISTEN states, also name is updated to better
describe what this function does now.

iwlwifi: pcie: stop the firmware when we restart it
In case the firmware didn't assert but we want to restart
it, e.g. we didn't get the reply for a host command, or the
Tx queues are stuck, we should stop the firmware by
provoking an interrupt. This allows to better debug the
firmware in these bad scenarios.

mac80211: allow driver to return error from sched_scan_stop
In order to solve races with sched_scan_stop, it is necessary
for the driver to be able to return an error to propagate that

Due to userspace assumptions, the sched_scan_stop operation must
be synchronous, i.e. once it returns a new scheduled scan must be
able to start immediately. Document this in the API.

cfg80211: Pass TDLS peer capability information in tdls_mgmt
While framing the TDLS Setup Confirmation frame, the driver needs to
know if the TDLS peer is VHT/HT/WMM capable and thus shall construct
the VHT/HT operation / WMM parameter elements accordingly. Supplicant
determines if the TDLS peer is VHT/HT/WMM capable based on the
presence of the respective IEs in the received TDLS Setup Response frame.
The host driver should not need to parse the received TDLS Response
frame and thus, should be able to rely on the supplicant to indicate
the capability of the peer through additional flags while transmitting
the TDLS Setup Confirmation frame through tdls_mgmt operations.

What really is needed is an option to force using the static address

the controller does actually have a public address. For single mode
LE only controllers this option will not be available.
