Driver is using boolean variables to maintain vairous status
information of adapter. These status variables are accessed by
multiple threads and there is a possibility of a race. To avoid
this, convert these variables to a set of bitops flags, to be
operated atomically.
Below variables of mwifiex_adapter are converted to bitop flags:
surprise_removed
is_cmd_timedout
is_suspended
is_hs_configured

The BIT macro uses unsigned long which some architectures handle as 32 bit
and therefore might cause macro's shift to overflow when used on a value
equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards).
Since 'filled' member in station_info changed to u64, BIT_ULL macro
should be used with all NL80211_STA_INFO_* attribute types instead of BIT
to prevent future possible bugs when one will use BIT macro for higher
attributes by mistake.
This commit cleans up all usages of BIT macro with the above field
in wireless-drivers by changing it to BIT_ULL instead. In addition, there are
some places which don't use BIT nor BIT_ULL macros so align those as well.

When a user requests scan, driver sends multiple scan requests
to firmware, which might be active or passive. Firmware will
send channel statistics for each channel in the request. This will
be stored in chan_stats array.
Few channels might report hidden SSIDs in passive scan results.
So, once the original scan request is finished, driver issues an
active scan request for all channels which reported hidden SSIDs.
This will cause duplicates in the chan_stats array. At worst,
every channel will have a hidden SSID, in which case the driver
can issue active scan requests for each channel. So the complete
scan statistics size will be twice of existing limit.
At present maximum number of channels returned in scan statistics
is 31(BG) + 14(A) = 45. Clearly there will be an overflow of the
chan_stats array in the above mentioned scenario. To fix this
double the size of chan_stats array.

When we leave the delete interface function, there are still netdev
hooks that might try to process the device. We're short-circuiting some
of that by changing the interface type and clearing ieee80211_ptr. This
means we skip NETDEV_UNREGISTER_FINAL in cfg80211. Fortunately, that is
currently a no-op.
We don't need most of the cleanup here anyway:
* the connection state will get (un)set as part of the disconnect
process (which cfg80211 already initiates for us)
* the interface type doesn't actually need to be cleared at all (it'll
trigger a WARN_ON() in cfg80211 if we do)
* the iee80211_ptr isn't really "ours" to clear anyway

mwifiex records information about various channels as it receives scan
information. It does this by appending to a buffer that was sized
to the max number of supported channels on any band, but there are
numerous problems:
(a) scans can return info from more than one band (e.g., both 2.4 and 5
GHz), so the determined "max" is not large enough
(b) some firmware appears to return multiple results for a given
channel, so the max *really* isn't large enough
(c) there is no bounds checking when stashing these stats, so problems
(a) and (b) can easily lead to buffer overflows
Let's patch this by setting a slightly-more-correct max (that accounts
for a combination of both 2.4G and 5G bands) and adding a bounds check
when writing to our statistics buffer.
Due to problem (b), we still might not properly report all known survey
information (e.g., with "iw <dev> survey dump"), since duplicate results
(or otherwise "larger than expected" results) will cause some
truncation. But that's a problem for a future bugfix.
(And because of this known deficiency, only log the excess at the WARN
level, since that isn't visible by default in this driver and would
otherwise be a bit too noisy.)

If we fail to add an interface in mwifiex_add_virtual_intf(), we might
hit a BUG_ON() in the networking code, because we didn't tear things
down properly. Among the problems:
(a) when failing to allocate workqueues, we fail to unregister the
netdev before calling free_netdev()
(b) even if we do try to unregister the netdev, we're still holding the
rtnl lock, so the device never properly unregistered; we'll be at
state NETREG_UNREGISTERING, and then hit free_netdev()'s:
BUG_ON(dev->reg_state != NETREG_UNREGISTERED);
(c) we're allocating some dependent resources (e.g., DFS workqueues)
after we've registered the interface; this may or may not cause
problems, but it's good practice to allocate these before registering
(d) we're not even trying to unwind anything when mwifiex_send_cmd() or
mwifiex_sta_init_cmd() fail
To fix these issues, let's:
* add a stacked set of error handling labels, to keep error handling
consistent and properly ordered (resolving (a) and (d))
* move the workqueue allocations before the registration (to resolve
(c); also resolves (b) by avoiding error cases where we have to
unregister)
[Incidentally, it's pretty easy to interrupt the alloc_workqueue() in,
e.g., the following:
iw phy phy0 interface add mlan0 type station
by sending it SIGTERM.]
This bugfix covers commits like commit 7d652034d1 ("mwifiex: channel

back to the introduction of dynamic interface handling in commit
93a1df48d2 ("mwifiex: add cfg80211 handlers add/del_virtual_intf").

This patch implements the idea to have multiple scheduled scan requests
running concurrently. It mainly illustrates how to deal with the incoming
request from user-space in terms of backward compatibility. In order to
use multiple scheduled scans user-space needs to provide a flag attribute
NL80211_ATTR_SCHED_SCAN_MULTI to indicate support. If not the request is
treated as a legacy scan.
Drivers currently supporting scheduled scan are now indicating they support
a single scheduled scan request. This obsoletes WIPHY_FLAG_SUPPORTS_SCHED_SCAN.

nl80211 provides the NL80211_SCAN_FLAG_RANDOM_ADDR for every scan
request that should be randomized; the absence of such a flag means we
should not randomize. However, mwifiex was stashing the latest
randomization request and *always* using it for future scans, even those
that didn't set the flag.
Let's zero out the randomization info whenever we get a scan request

priv->random_mac entirely (and plumb the randomization MAC properly

3) In 'net' we had several probe error path bug fixes to the
stmmac driver, meanwhile a lot of this code was cleaned up
and reorganized in 'net-next'.
4) The cls_flower classifier obtained a helper function in
'net-next' called __fl_delete() and this overlapped with
Daniel Borkamann's bug fix to use RCU for object destruction
in 'net'. It also overlapped with Jiri's change to guard
the rhashtable_remove_fast() call with a check against
tc_skip_sw().
5) In mlx4, a revert bug fix in 'net' overlapped with some
unrelated changes in 'net-next'.
6) In geneve, a stale header pointer after pskb_expand_head()
bug fix in 'net' overlapped with a large reorganization of
the same code in 'net-next'. Since the 'net-next' code no
