NFC: implicitly deactivate in nci_start_poll

When start_poll is called, and a target was implicitly activated,
we need to implicitly deactivate it.
On the other hand, when the target was activated by the user,
we should not deactivate it.

mwifiex: update bss band information

In recent commit "mwifiex: use cfg80211 dynamic scan..."
(7c6fa2a843..) 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.

Sometimes association in 5GHz doesn't work. Dmesg log shows

while preparing scan channel list for firmware Null entries

this list ignores channels after Null entry. Hence sometimes

libertas: scan behaviour consistency improvements

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.

cfg80211: Remove strict validation of AKM suites

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

iwlagn: do not use interruptible waits

Since the dawn of its time, iwlwifi has used
interruptible waits to wait for synchronous
commands and firmware loading.

This leads to "interesting" bugs, because it
can't actually handle the interruptions; for
example when a command sending is interrupted
it will assume the command completed fully,
and then leave it pending, which leads to all
kinds of trouble when the command finishes
later.

Since there's no easy way to gracefully deal
with interruptions, fix the driver to not use
interruptible waits.

This at least fixes the error
iwlagn 0000:02:00.0: Error: Response NULL in  'REPLY_SCAN_ABORT_CMD'
