50ea05efaf mac80211: pass block ack session timeout to to driver
Currently mac80211 does not inform the driver of the session
block ack timeout when starting a rx aggregation session.
Drivers that manage the reorder buffer need to know this
parameter.
Seeing that there are now too many arguments for the
drv_ampdu_action() function, wrap them inside a structure.

0ead2510f8 mac80211: allow the driver to send EOSP when needed
This can happen when the driver needs to send less frames
than expected and then needs to close the SP.
Mac80211 still needs to set the more_data properly based
on its buffer state (ps_tx_buffer and buffered frames on
other TIDs).
To that end, refactor the code that delivers frames upon
uAPSD trigger frames to be able to get only the more_data
bit without actually delivering those frames in case the
driver is just asking to set a NDP with EOSP and MORE_DATA
bit properly set.

1b09b5568e mac80211: introduce per vif frame registration API
Currently the cfg80211's frame registration api receives wdev, however
mac80211 assumes per device filter configuration and ignores wdev.
Per device filtering is too wasteful, especially for multi-channel
devices.
Introduce new per vif frame registration API and use it for probe
request registrations in ieee80211_mgmt_frame_register()
Also call directly to ieee80211_configure_filter instead of using a work
since it is now allowed to sleep in ieee80211_mgmt_frame_register.

1bc1e4d048 mac80211: Move message tracepoints to their own header
Every tracing file must have its own TRACE_SYSTEM defined.
The mac80211 tracepoint header broke this and add in the middle
of the file had:

 #undef TRACE_SYSTEM
 #define TRACE_SYSTEM mac80211_msg

Unfortunately, this broke new code in the ftrace infrastructure.
Moving the mac80211_msg into its own trace file with its own
TRACE_SYSTEM defined fixes the issue.

ba8c3d6f16 mac80211: add an intermediate software queue implementation
This allows drivers to request per-vif and per-sta-tid queues from which
they can pull frames. This makes it easier to keep the hardware queues
short, and to improve fairness between clients and vifs.

The task of scheduling packet transmission is left up to the driver -
queueing is controlled by mac80211. Drivers can only dequeue packets by
calling ieee80211_tx_dequeue. This makes it possible to add active queue
management later without changing drivers using this code.

This can also be used as a starting point to implement A-MSDU
aggregation in a way that does not add artificially induced latency.

2b9a7e1bac mac80211: allow drivers to provide most station statistics
In many cases, drivers can filter things like beacons that will
skew statistics reported by mac80211. To get correct statistics
in these cases, call drivers to obtain statistics and let them
override all values, filling values from mac80211 if the driver
didn't provide them. Not all of them make sense for the driver
to fill, so some are still always done by mac80211.

Note that this doesn't currently allow a driver to say "I know
this value is wrong, don't report it at all", or to sum it up
with a mac80211 value (as could be useful for "dropped misc"),
that can be added if it turns out to be needed.

This also gets rid of the get_rssi() method as is can now be
implemented using sta_statistics().

1a5f0c13d1 mac80211: add a single-transaction driver op to switch contexts
In some cases, when the driver is already using all the channel
contexts it can handle at once, we have to do an in-place switch
(ie. we cannot afford using an extra context temporarily for the
transaction).  But some drivers may not support switching the channel
context assigned to a vif on the fly (ie. without unassigning and
assigning it) while others may only work if the context is changed on
the fly, without unassigning it first.

To allow these different scenarios, add a new driver operation that
let's the driver decide how to handle an in-place switch.

6a9d1b91f3 mac80211: add pre-RCU-sync sta removal driver operation
Currently, mac80211 allows drivers to keep RCU-protected station
references that are cleared when the station is removed from the
driver and consequently needs to synchronize twice, once before
removing the station from the driver (so it can guarantee that
the station is no longer used in TX towards the driver) and once
after the station is removed from the driver.

Add a new pre-RCU-synchronisation station removal operation to
the API to allow drivers to clear/invalidate their RCU-protected
station pointers before the RCU synchronisation.

This will allow removing the second synchronisation by changing
the driver API so that the driver may no longer assume a valid
RCU-protected pointer after sta_remove/sta_state returns.

The alternative to this would be to synchronize_rcu() in all the
drivers that currently rely on this behaviour (only iwlmvm) but
that would defeat the purpose.

Add a new field to ieee80211_chanctx_conf to indicate
the min required channel configuration.

Tuning to a narrower channel might help reducing
the noise level and saving some power.

The min required channel definition is the max of
all min required channel definitions of the interfaces
bound to this channel context.

In AP mode, use 20MHz when there are no connected station.
When a new station is added/removed, calculate the new max
bandwidth supported by any of the stations (e.g. 80MHz when
80MHz and 40MHz stations are connected).

In other cases, simply use bss_conf.chandef as the
min required chandef.

Notify drivers about changes to this field by calling
drv_change_chanctx with a new CHANGE_MIN_WIDTH notification.

85220d71bf mac80211: support secondary channel offset in CSA
Add support for the secondary channel offset IE in channel
switch announcements. This is necessary for proper handling
of CSA on HT access points.

For this to work it is also necessary to convert everything
here to use chandef structs instead of just channels. The
driver updates aren't really correct though. In particular,
the TI wl18xx driver update can't possibly be right since
it just ignores the new channel width for lack of firmware
API.

675a0b049a mac80211: Use a cfg80211_chan_def in ieee80211_hw_conf_chan
Drivers that don't use chanctxes cannot perform VHT association because
they still use a "backward compatibility" pair of {ieee80211_channel,
nl80211_channel_type} in ieee80211_conf and ieee80211_local.

39ecc01d1b mac80211: pass queue bitmap to flush operation
There are a number of situations in which mac80211 only
really needs to flush queues for one virtual interface,
and in fact during this frames might be transmitted on
other virtual interfaces. Calculate and pass a queue
bitmap to the driver so it knows which queues to flush.

488b366a45 mac80211: add driver callback for per-interface multicast filter
Some devices have multicast filter capability for each individual
virtual interface rather than just a global one. Add an interface
specific driver callback allowing such drivers to configure this.

d339d5ca8e mac80211: Allow drivers to differentiate between ROC types
Some devices can handle remain on channel requests differently
based on the request type/priority. Add support to
differentiate between different ROC types, i.e., indicate that
the ROC is required for sending managment frames.

15ac7c478f mac80211: Fix incorrect use of STA_PR_FMT in trace points
Several tracepoints are using STA_PR_FMT where STA_PR_ARG should be
used, resulting in messages like "phy0 sta:ARG TYPE NOT FIELD BUT 1".
Change these to STA_PR_ARG.

164eb02d07 mac80211: add radar detection command/event
Add command to trigger radar detection in the driver/FW.
Once radar detection is started it should continuously
monitor for radars as long as the channel active.
If radar is detected usermode notified with 'radar
detected' event.

Scanning and remain on channel functionality must be disabled
while doing radar detection/scanning, and vice versa.
