Kelvin. Remove support for this.

If iwl_scan_initiate() fails for any reason,
priv->scan_request and priv->scan_vif are left
dangling. This can lead to a crash later when
iwl_bg_scan_completed() tries to run a pending
scan request.

In practice, this seems to be very rare due to
the STATUS_SCANNING check earlier. That check,
however, is wrong -- it should allow a scan to
be queued when a reset/roc scan is going on.
When a normal scan is already going on, a new
one can't be issued by mac80211, so that code
can be removed completely. I introduced this
bug when adding off-channel support in commit
266af4c7.

Since all the queue logic has been moved to the transport layer,
the sequence number is set in the transport layer.
While doing that I forgot that the mac header is copied to the
TB of the TX cmd in the upper layer before the call to the transport
layer. So basically we used the sequence number from mac80211...
This was fine for the first assocation but after the second, mac80211
resets its counters while we don't hence a shift that led to terrible
impact on performance.

In recent commit "mwifiex: use cfg80211 dynamic scan..."
(7c6fa2a8..) scan table handling in driver is removed to
make use of cfg80211 dynamic scan table. Now driver sends
beacon buffers found in scanning directly to stack and parse
the buffer for requested BSS only during association.

Beacon buffer doesn't contain bss band information. Driver
gets it from firmware in separate tlv (chan_band_tlv).
Currently since we don't inform stack about bss bandinfo,
there is an issue with 5GHz association.

Use "priv" field of struct cfg80211_bss to store bandinfo.
This fixes 5GHz association issue.

Sometimes association in 5GHz doesn't work. Dmesg log shows
"Can not find requested SSID xyz" error message. Currently
while preparing scan channel list for firmware Null entries
are created for disabled channels. The routine which retrieves
this list ignores channels after Null entry. Hence sometimes
driver doesn't scan the channel of requested AP and association
fails. The issue is fixed by avoiding those NULL entries.

When scanning for the broadcast SSID, there is no need to add the
SSID TLV (restoring the behaviour of the driver behaviour in the wext
days, confirmed in Marvell specifications).

If bssid is unspecified, the current scan code will usually fire off an
active scan probing for the specific requested SSID. However, if a scan
is ongoing (or has just finished), those scan results will be used
instead (even if that scan is totally different, e.g. a passive scan on
channel 4 for a different SSID). Fix this inconsistency by always
firing off a scan when associating without a bssid.

Instead of using a hardcoded list of cipher suites in nl80211.c, use a

NL80211_ATTR_AKM_SUITES can be used to configure new AKMs, like FT or
the SHA-256 -based AKMs or FT from 802.11r/802.11w. In addition, vendor
specific AKMs could be used. The current validation code for the connect
command prevents cfg80211-based drivers from using these mechanisms even
if the driver would not actually use this AKM value (i.e., it uses
WPA/RSN IE from user space). mac80211-based drivers allow any AKM to be
used since this value is not used there.

Remove the unnecessary validation step in cfg80211 to allow drivers to
decide what AKMs are supported. In theory, we could handle this by
advertising supported AKMs, but that would not be very effective unless
we enforce all drivers (including mac80211) to advertise the set of
supported AKMs. This would require additional changes in many places
whenever a new AKM is introduced even though no actually functionality
changes may be required in most drivers.
