In P2P device mode, the device needs to have valid
QoS parameters. We currently have those because we
program parameters from any virtual interface into
all contexts, but not only do we want to get rid of
this -- it is also unpredictable since on the BSS
context we might have any parameters, and there it
might even be programmed for HT.
Explicitly program default QoS parameters into the
PAN context for P2P (the defaults are 11g but with
QoS disabled) to make device behaviour predictable.
This also helps when in a follow-up patch we will
use TX QoS parameters from mac80211 only for the
context they were meant for -- without this first
that would completely break P2P device discovery.

Reinette reports a crash in iwl_reprogram_ap_sta(). The
debugging shows:
b1 16 mov $0x16,%cl
*f3 a5 rep movsl %ds <-- trapping instruction:(%rsi),%es:(%rdi)
which is a memcpy of 22 (0x16) words (movsl). this points
to "priv->stations[sta_id].lq" being NULL since that is
the memcpy() of that size here.
The only way I see for this to happen is if we try to
do some RXON reprogramming while connecting to an AP,
after tx_sync() but before full setup, but that seems
like something that might very well happen.
Fix this by checking if the LQ is present and only then
reprogramming it.

When a station is associated with an AP and the RF_KILL switch is engaged,
numerous error messages were sent to the system log. The error messages
were the result of the failure(s) of the various submodules to perform
their tasks after the radios were disabled.
To resolve this situation, the messages were modified to use a new macro,
IWL_DEBUG_QUIET_RFKILL. This macro allows for the RF_KILL error messages
to be sent to the log provided that IWL_DEBUG is true and IWL_DL_RADIO
is '1'. For all other cases, the error messages resulting from an RFKILL
event will not be sent to the system log. Messages logged because of an
RFKILL will be tagged with the prefix '(RFKILL)' to clarify the cause of
the error.

Whether to use NoA or not is entire controlled
by the uCode right now, and it also adds the
attribute to beacons. We do need to add it to
probe responses in the driver though.
Keep track of the NoA notification from the
uCode and add the data to probe responses when
such are transmitted. Use RCU to manage the
lifetime.

John reported the following warning:
net/wireless/nl80211.c: In function ‘nl80211_tx_mgmt’:
net/wireless/nl80211.c:5286:8: warning: ‘hdr’ may be used uninitialized in this function
Evidently, his version of gcc isn't able to see that
when "msg" is initialized, "hdr" must also be. My
gcc, 4.6.1, can actually see that and doesn't warn.
Simply initialize the variable to NULL. That means
if the compiler was ever right we'll crash though so
isn't really optimal since it may hide warnings from
the compiler when somebody modifies this code in the
future.

Cfg80211 stack allocates private area for driver use in
struct cfg80211_bss. It will be freed by stack in bss_release().
Driver don't need to worry about it.
In mwifiex driver, we use the private area just to store band
information(u8). We don't allocate memory explicitly and store
it's pointer in bss->priv. Hence we don't have any cleanup work
to do in free_priv handler. Currently we try to free the allocated
private area in free_priv handler which is not correct.
This patch removes unnecessary free_priv handler.

The problem with PSM when a hidden SSID was used was originally
reported by Juuso Oikarinen.
- When generally scanning, the AP is getting a bss entry with
a zero SSID.
- When associating, a probe-req is sent to the AP with the SSID,
and as a result a probe-response is received with the hidden
SSID in place. As a consequence, a second bss entry is created
for the AP, now with the real SSID.
- After association, mac80211 executes ieee80211_recalc_ps(),
but does not switch to powersave because the beacon-ies are missing.
As result, the STA does not ever enter PSM.
The patch merges in beacon ies of hidden bss from beacon to the probe
response, creating a consistent set of ies in place.
Patch is depended on "cfg80211: fix cmp_ies" made by Johannes.
