Group station statistics by where they're (mostly) updated
(TX, RX and TX-status) and group them into sub-structs of
the struct sta_info.
Also rename the variables since the grouping now makes it
obvious where they belong.
This makes it easier to identify where the statistics are
updated in the code, and thus easier to think about them.

There's little point in keeping (and even sending to userspace)
the beacon_loss_count value per station, since it can only apply
to the AP on a managed-mode connection. Move the value to ifmgd,
advertise it only in managed mode, and remove it from ethtool as
it's available through better interfaces.

This file only feeds a debugfs file that isn't very useful, so remove
it. If necessary, we can add other ways to get this information, for
example in the NL80211_CMD_PROBE_CLIENT response.

The function is void and static, so just ifdef its contents
instead of duplicating the declaration.

Printing "N/A mBi" is strange - print just "N/A" instead.
Also add a missing opening parenthesis.

Instead of having a lot of places that free ignored requests
and then return REG_REQ_OK, make reg_process_hint() process
REG_REQ_IGNORE by freeing the request, and let functions it
calls return that instead of freeing.
This also fixes a leak when a second (different) country IE
hint was ignored.

This function can only deal with treatment values OK and ALREADY_SET
so make the callees not return anything else and warn if they do.

If there's a built-in regulatory database, there may be little point
in also calling out to CRDA and failing if the system is configured
that way. Allow removing CRDA support to save ~1K kernel size.

When the functions reg_set_rd_driver() and reg_set_rd_country_ie()
return with an error, the calling function already restores data
by calling restore_regulatory_settings(), so there's no need to
also schedule a timeout (which would lead to other side effects
such as indicating CRDA failed, which clearly isn't true.) Remove
the scheduling.

Instead of searching the built-in database only in the worker,
search it directly and return an error if the entry cannot be
found (or memory cannot be allocated.) This means that builtin
database queries no longer rely on the timeout.

The new name is more appropriate since in the case of a built-in
database it may not really rely on CRDA.

The function reg_call_crda() can't actually validly return
REG_REQ_IGNORE as it does now when calling CRDA fails since
that return value isn't handled properly. Fix that.

That file contains just a single function, which itself is just a
single statement to call a different function. Remove it.

There's only a single caller of this function, so it can
be moved to the same file and made static.

As this API has never really seen any use and most drivers don't
ever use the value derived from it, remove it.
Change the only driver using it (rt2x00) to simply use the DTIM
period instead of the "max sleep" time.

If multiple scan plans were set for scheduled scan, do not restart
scheduled scan on reconfig because it is possible that some scan
plans were already completed and there is no need to run them all
over again. Instead, notify userspace that scheduled scan stopped
so it can configure new scan plans for scheduled scan.

Add the option to configure multiple 'scan plans' for scheduled scan.
Each 'scan plan' defines the number of scan cycles and the interval
between scans. The scan plans are executed in the order they were
configured. The last scan plan will always run infinitely and thus
defines only the interval between scans.
The maximum number of scan plans supported by the device and the
maximum number of iterations in a single scan plan are advertised
to userspace so it can configure the scan plans appropriately.
When scheduled scan results are received there is no way to know which
scan plan is being currently executed, so there is no way to know when
the next scan iteration will start. This is not a problem, however.
The scan start timestamp is only used for flushing old scan results,
and there is no difference between flushing all results received until
the end of the previous iteration or the start of the current one,
since no results will be received in between.
