It is possible that there are different BSS structs with
the same BSSID, but we cannot authenticate with multiple
of them them because we need the BSSID to be unique for
deauthenticating/disassociating.

In order to avoid problems with BSS structs going away
while they're in use, I've long wanted to make cfg80211
keep track of them. Without the SME, that wasn't doable
but now that we have the SME we can do this too. It can
keep track of up to four separate authentications and
one association, regardless of whether it's controlled
by the cfg80211 SME or the userspace SME.

When the interface is brought down, we need to
reset the auth algorithm because wpa_supplicant
doesn't reset it, and then we fail to use shared
key auth when required later.

When the userspace SME is in control, we are currently not sending
events, but this means that any userspace applications using wext
or nl80211 to receive events will not know what's going on unless
they can also interpret the nl80211 assoc event. Since we have all
the required code, let the SME follow events from the userspace
SME, this even means that you will be refused to connect() while
the userspace SME is in control and connected.

With mac80211 now always controlled by an external SME,
a lot of code is dead -- SSID, BSSID, channel selection
is always done externally, etc. Additionally, rename
IEEE80211_STA_TKIP_WEP_USED to IEEE80211_STA_DISABLE_11N
and clean up the code a bit.

The IEEE80211_STA_TKIP_WEP_USED flag is used internally to
disable HT when WEP or TKIP are used. Now that cfg80211 is
giving us the required information, we can set the flag

By dropping the noise reporting, we can implement

For now, let's implement that using a very hackish way:

This adds code to make it possible to use the cfg80211
connect() API with wireless extensions, and because the
previous patch added emulation of that API with auth()
and assoc(), by extension also supports wext on that.
At the same time, removes code from mac80211 for wext,
but doesn't yet clean up mac80211's mlme code more.

This adds code to cfg80211 so that drivers (mac80211 right

This patch introduces the cfg80211 connect/disconnect API.
The goal here is to run the AUTH and ASSOC steps in one call.
This is needed for some fullmac cards that run both steps
directly from the target, after the host driver sends a
connect command.
Additionally, all the new crypto parameters for connect()
are now also valid for associate() -- although associate
requires the IEs to be used, the information can be useful
for drivers and should be given.

This introduces a new NL80211_CMD_TESTMODE for testing
and calibration use with nl80211. There's no multiplexing
like like iwpriv had, and the command is not available by
default, it needs to be explicitly enabled in Kconfig and
shouldn't be enabled in most kernels.
The command requires a wiphy index or interface index to
identify the device to operate on, and the new TESTDATA
attribute. There also is API for sending replies to the
command, and testmode multicast messages (on a testmode
multicast group).
I've also updated mac80211 to be able to pass through the
command to the driver, since it itself doesn't implement
the testmode command.
Additionally, to give people an idea of how to use the
command, I've added a little code to hwsim that makes use
of the new command to set the powersave mode, this is
currently done via debugfs and should remain there, and
the testmode command only serves as an example of how to
use this best -- with nested netlink attributes in the
TESTDATA attribute. A hwsim testmode tool can be found at
http://git.sipsolutions.net/hwsim.git/. This tool is BSD
licensed so people can easily use it as a basis for their
own internal fabrication and validation tools.

When the auth algorithm is rejected, but we don't have
another one to try, we will eventually retry but that
isn't useful -- we'll then do it again and again until
we eventually give up. Instead, we should let the SME
know and go into disabled state. The same applies for
situations where the AP rejects with any other status
code.
Additionally, when trying the next auth algorithm, we
should reset the auth_tries so that just a single lost
frame doesn't lead to us giving up on the third auth
algorithm.

Instead of hardcoding GFP_ATOMIC everywhere, add a

The way I initially thought we could do wireless extensions
is by making all the compat code in cfg80211 be independent
of CONFIG_WIRELESS_EXT, but this is turning out to not be
feasible. Therefore, fix the Kconfig help text and make the
option default to yes, so people won't get a nasty surprise
when mac80211 will get rid of its 'select WIRELESS_EXT' any
time now.

Currently, wext drivers cannot return NULL for stats even though
that would make the ioctl return -EOPNOTSUPP because that would
mean they are no longer listed in /proc/net/wireless. This patch
changes the wext core's behaviour to list them if they have any
wireless_handlers, but only show their stats when available, so
that drivers can start returning NULL if stats are currently not
available, reducing confusion for e.g. IBSS.

This removes the custom scan cache used by orinoco.
We also have to avoid calling cfg80211_scan_done from the hard
interrupt, so we offload the entirety of scan processing to a workqueue.
This may behave strangely if you start scanning just prior to
suspending...

Initialise and register a wiphy.
Store the orinoco_private structure in the new wiphy, and use the
net_device private area to store the wireless_dev. This results in a
change to the way we navigate from a net_device to the driver private
orinoco_private, which we encapsulate in the inline function ndev_priv.
Most of the remaining calls to netdev_priv are thus replaced by
ndev_priv.
We can immediately rely on cfg80211 to handle SIOCGIWNAME, so
orinoco_ioctl_getname is removed.
