In some cases, like in the rsi driver hardware scan offload, there
may be scenarios in which hardware scan might not be available or
desirable.

Allow drivers to cope with this by letting them fall back to software
scan by returning the special value 1 from the hardware scan method.

Small merge conflict in net/mac80211/scan.c, I preserved
the kcalloc() conversion. -DaveM

Johannes Berg says:

====================
This round's updates:
 * finally some of the promised HE code, but it turns
   out to be small - but everything kept changing, so
   one part I did in the driver was &gt;30 patches for
   what was ultimately &lt;200 lines of code ... similar
   here for this code.
 * improved scan privacy support - can now specify scan
   flags for randomizing the sequence number as well as
   reducing the probe request element content
 * rfkill cleanups
 * a timekeeping cleanup from Arnd
 * various other cleanups
====================

Support the new random SN and minimal probe request contents
scan flags for the case of software scan - for hardware scan
the drivers need to opt in, but may need to do only that,
depending on their implementation.

This function is passed many more parameters in the scan case
than in the MLME case, and differentiates the two cases inside.
Split it up and make both versions static to simplify things.

The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:

        kzalloc(a * b, gfp)

with:
        kcalloc(a * b, gfp)

as well as handling cases of:

        kzalloc(a * b * c, gfp)

with:

        kzalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kzalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kzalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

When the low-level driver returns an invalid RSSI indication,
set the signal value to 0 as an indication to the upper layer.

Also, skip average level computation if signal is invalid.

One of OCE's optimizations is acception of broadcast probe responses.
Accept broadcast probe responses but don't set
NL80211_EXT_FEATURE_ACCEPT_BCAST_PROBE_RESP. Because a device's firmware
may filter out the broadcast probe resp - drivers should set this flag.

<content type='text'>
We currently use a lot of flags that are mutually incompatible,
separate this out into actual encoding and bandwidth enum values.

Much of this again done with spatch, with manual post-editing,
mostly to add the switch statements and get rid of the conversions.
